Parasitoids of Chrysopidae Eggs in Sinaloa Mexico.

Simple SummaryFour species of wasps, Myartsevaia chrysopae, Telenomus lobatus, Telenomus tridentatus and Trichogramma atopovirilia, are recorded as parasitoids of chrysopid eggs in Mexico, for the first time. The field survey was conducted in sorghum and corn in different locations in Sinaloa, Mexico. The identification of the parasitoids was determined by morphology, and for both Telenomus species the barcode region of the cytochrome oxidase 1 gene (CO1) was amplified and sequenced.The eggs parasitoids Myartsevaia chrysopae (Crawford) (Hymenoptera: Encyrtidae), Telenomus lobatus Johnson, Telenomus tridentatus Johnson (Hymenoptera: Scelionidae) and Trichogramma atopovirilia Oatman and Platner (Hymenoptera: Trichogrammatidae) are reported for the first time or in new localities in Mexico. Their occurrence was first discovered in 2018 during a survey of parasitism on chrysopid eggs, conducted on Sorghum bicolor L. Moench (Poales: Poaceae) and Zea mays L. (Poales: Poaceae) in different locations in Sinaloa, Mexico. The identity of the parasitoids was determined by morphology and for both species of Telenomus the barcode region of the cytochrome oxidase 1 gene (CO1) was generated to facilitate molecular diagnosis of these species in future studies.

Two new species and new records in the alpheid shrimp genera Salmoneus Holthuis, 1955 and Deioneus Dworschak, Anker amp; Abed-Navandi, 2000 in the Atlantic Ocean (Malacostraca: Decapoda).

The present study deals with two species new to science, as well as several new records in the closely related alpheid shrimp genera Salmoneus Holthuis, 1955 and Deioneus Dworschak, Anker Abed-Navandi, 2000, based on material collected at various localities in the tropical western and eastern Atlantic Ocean. In the western Atlantic, Salmoneus inconspicuus sp. nov. is described based on material from the Caribbean coast of Panama, Cuba, French Antilles and (with some doubts) Bermuda. The new species has been previously reported from the eastern Caribbean Sea as S. teres Manning Chace, 1990, a closely related species so far known only from Ascension Island in the central Atlantic. Salmoneus camaroncito Anker, 2010 is reported from the Caribbean coast of Mexico, for the first time since its original description. Salmoneus carvachoi Anker, 2007 is reported from Colombia and southeastern USA, representing a new record of the species for each of these countries. Salmoneus depressus Anker, 2011 and Salmoneus setosus Manning Chace, 1990 are reported for the first time from Cuba and Panama, respectively. In addition, these two species, as well as Salmoneus wehrtmanni Anker, 2010, are reported from new localities in Mexico. In the eastern Atlantic, Salmoneus saotomensis sp. nov. is described based on a single specimen from São Tomé Island in the Gulf of Guinea. The new species is characterised by the somewhat enlarged minor cheliped and is compared to all other Atlantic species presenting this feature.Deioneus sandizelli Dworschak, Anker Abed-Navandi, 2000 is reported from São Tomé Island, for the first second time since its original description based on the Cape Verde type material. The characters separating Deioneus and Salmoneus are reassessed. The new evidence shows that these two genera are distinguished by only one morphological feature known to be variable in at least one non-related alpheid genus. However, in view of the increasing morphological heterogeneity in Salmoneus, it seems more appropriate to retain Deioneus as a valid genus for it may represent a distinct clade that also includes several other species currently placed in Salmoneus.

Wulfenite Localities in New Mexico: The Famous and the Forgotten

The famous and the forgotten—one wulfenite locality stands supreme in the annals of New Mexico collecting: the Stephenson-Bennett mine in Dona Ana County in the southern part of the state. Wulfenit...

Mecaster batnensis (Coquand, 1862), a late Cenomanian echinoid from New Mexico, with a compilation of Late Cretaceous echinoid records in the Western Interior of the United States and Canada

Abstract Echinoids are rare in the Upper Cretaceous of the Western Interior, where fewer than 60 unique occurrences are known to date, most of these represented by only a few tests or isolated spines. A notable exception is the Carthage coal field (Socorro County, New Mexico), where more than 200 specimens of Mecaster batnensis, previously referred to as Hemiaster jacksoni Maury, 1925, have been collected from the basal Bridge Creek Limestone Beds of the Tokay Tongue of the Mancos Shale. Prolific occurrences from the same beds are known from elsewhere in west-central and southwest New Mexico. Recorded originally from the Upper Cretaceous of Algeria, M. batnensis is a small- to medium-sized, irregular echinoid that is confined to the upper Cenomanian Euomphaloceras septemseriatum Zone in New Mexico. Measurements on 169 well-preserved specimens from two localities in New Mexico document a species that is, on average, 21.0 mm long, 19.8 mm wide, and 15.1 mm tall, yielding a width/length ratio of 0.94 and a height/length ratio of 0.72. Graphs plotting width against length and height against length are strongly linear. The Western Interior echinoid record spans the entire Late Cretaceous, although there are no records from rocks of Santonian age. Localities are spread from New Mexico on the south to Alberta on the north. Preservation ranges from coarse internal molds in high-energy sandstones to original tests in low-energy limestones.

U-Pb geochronology of 1.1 Ga diabase in the southwestern United States: Testing models for the origin of a post-Grenville large igneous province

Late Mesoproterozoic mafic magmatism in the southwestern U.S. diabase province is expressed as diabase dikes, sills, sheets, and flows. Previous radiometric ages range from 1140 Ma to 1040 Ma. We used high-precision thermal ionization mass spectrometry to date baddeleyite in diabase from four localities in Arizona to obtain 206 Pb/ 238 U dates of 1080 ± 2 Ma, 1080 ± 3 Ma, 1088 ± 3 Ma, and 1094 ± 2 Ma. We also obtained single-crystal laser-ablation and ion microprobe ages on zircons from two localities in New Mexico that indicate a wider geographic extent of this diabase province. The samples have SiO 2 ranging from 46.6 to 50.1 wt%, Mg# from 67 to 83, and e Nd ranging from +4.7 to -1.4. A compilation of previously published ages of silicic rocks in the same age range suggests that mantle-derived magma induced crustal anatexis resulting in silicic magmatism, and this bimodal event forms a large igneous province that stretches 1500 km from east to west and 500–1000 km from north to south. Because some of the ca. 1.1 Ga plutonism extends outside the United States into northern Mexico, we suggest renaming this event as the Southwestern Laurentia large igneous province (SWLLIP). Magmatism in the province from 1094 to 1080 Ma occurred largely after the end of the Grenville orogeny. Two models that are not mutually exclusive are proposed: (1) lithospheric delamination following the Grenville collision; and (2) arrival of a mantle plume beneath south-central Laurentia, which spread beneath the lithosphere, with a northward-heading portion causing Keweenawan magmatism (at the boundary with the Superior craton), and a southward-heading portion creating the Southwestern Laurentia large igneous province. Other large igneous provinces have been previously correlated to these events, but the 1075 Ma Warakurna large igneous province in Australia is too young, and the 1110 Ma events in the Amazonian Congo and Kalahari cratons are too old.

Augerinoichnus Helicoidalis, a new helical trace fossil from the nonmarine Permian of New Mexico

New Mexico contains a significant record of trace fossil assemblages, in terms of both abundance and ichnodiversity, from Lower Permian nonmarine depositional settings. Most notable amongst these are the trace fossil assemblages in the Robledo Mountains Formation of the Robledo Mountains in Doña Ana County, southern New Mexico, as recognized by the recent proposal to designate this area as a national monument. These trace fossil assemblages formed on a tidal flat under largely non-marine conditions (Mack and James, 1986; Hunt et al., 1993; Lucas et al., 1995a, 1998) and are dominated by the trackways of tetrapods and arthropods, yielding important information on the paleoecology, diversity and behavior of late Paleozoic arthropods (Braddy and Briggs, 2002; Minter and Braddy, 2006a), as well as evidence of specialized foraging strategies (Minter et al., 2006). Additional Lower Permian trace fossil assemblages occur at a number of localities in New Mexico and represent a variety of nonmarine depositional settings.

MORPHOLOGICAL ANALYSIS OF PEROGNATHUS FLAVUS AND P. MERRIAMI (RODENTIA: HETEROMYIDAE)

Morphometric variables were analyzed for 119 specimens from 28 localities in New Mexico and Texas to determine whether they can be used to distinguish between individuals of known identity of Perognathus flavus and P. merriami. Multivariate analysis of variance suggested that morphological characters from individuals of these 2 species differed significantly. Discriminant functions analysis produced 5 cranial and 2 external characters (bullar length, mastoid breadth, interorbital breadth, interparietal breadth, interparietal length, tail length, and hind foot length) that differed significantly in these 2 species. A subsequent classification analysis of 55 specimens from 21 localities was performed to test the utility of these characters in identifying unknown individuals, and 87% of the individuals were identified correctly.

LATE PLEISTOCENE ROADRUNNER (GEOCOCCYX) FROM KARTCHNER CAVERNS STATE PARK, SOUTHEASTERN ARIZONA

Abstract A right femur (KCSP-128) from late Pleistocene deposits (ca. 36,210 yr B.P.; Rancholabrean) in Kartchner Caverns State Park, southeastern Arizona, is identified as the larger-than-modern roadrunner, Geococcyx californianus conklingi. This large form is best known from late Pleistocene localities in New Mexico and Nuevo Leon, as well as from assumed mixed late Pleistocene/Holocene deposits from New Mexico, Texas, and Chihuahua. It has never been reported from Arizona. Fossils of the modern-sized form, Geococcyx californianus californianus, have been reported from late Pleistocene localities in California and New Mexico, and from mixed late Pleistocene/Holocene deposits in Chihuahua. Comparisons of the Kartchner Caverns specimen to modern G. c. californianus specimens, and to published data of fossil G. c. californianus and G. c. conklingi, indicate KCSP-128 is relatively larger than the G. c. conklingi data and notably larger than G. c. californianus. KCSP-128 is added to the Rancholabrean record ...

Persistence of the Meadow Jumping Mouse, Zapus hudsonius luteus, in New Mexico

Zapus hudsonius luteus is a subspecies of the meadow jumping mouse (Hafner et al., 1981) that is restricted to New Mexico and Arizona, where it occupies mesic habitats in lowland valleys and along montane streams (Bailey, 1913; Findley et al., 1975; Hafner et al., 1981; Hoffmeister, 1986). The subspecies has been reported from 14 localities in New Mexico (Hafner et al., 1981; R. D. Ohmart and V. C. Hink, in litt.) and 11 localities in Arizona (Hafner et al., 1981; Hall, 1981; Hoffmeister, 1986). In New Mexico, these records are from the San Juan Mountains (El Rito area), Sangre de Cristo Mountains (North Williams Lake), Jemez Mountains (upper Guadalupe River drainage), Sacramento Mountains (Rio Penasco and Silver Springs Creek), and the Rio Grande Valley (Espanola to the Bosque del Apache National Wildlife Refuge; Fig. 1). Southwestern populations of the genus Zapus were initially described by Miller (1911) as a distinct species, Zapus luteus, then as a subspecies of the western jumping mouse, Zapus princeps (Z. p. luteus), by Krutszch (1954). Based on genetic relationships between southwestern Zapus and other representatives of the genus, Hafner et al. (1981) concluded that these peripheral isolates were instead conspecific with the meadow jumping mouse, Z. hudsonius, and, therefore, considered them to be Z. h. luteus.

Taxonomy and variability of threeTexigryphaea(Bivalvia) species from their Lower Cretaceous (Albian) type localities in New Mexico and Oklahoma

The benthic, free-living oysterTexigryphaeawas the dominant constituent of many late Albian marine communities in the Texas and southern Western Interior regions. Large topotypic assemblages of three common lower–middle Washita Group species (T. naviaandT. pitcheriin Oklahoma andT. tucumcariiin New Mexico) each display considerable morphological variation in valve shape and the proportions and expression of various features. Variation within an assemblage is partly due to ontogenetic changes but is mainly ecophenotypic, with local variation in nature of substrate, water turbulence, length of attachment time, and other factors influencing the final morphology of the mature shell. TheT. naviaassemblage is distinct in several important morphological characters from the other species, and the differences become more pronounced with growth.Texigryphaea naviaappears to have been adapted to relatively firm substrates in moderately agitated conditions, in contrast to the other species, which occupied softer substrates in quieter environments. The essentially contemporaneousT. pitcheriandT. tucumcariiassemblages display much overlap in all measured dimensions of the left valve and in the range of intergrading morphs that compose each assemblage. Accordingly,T. tucumcariiis considered a synonym ofT. pitcheri, representing populations of that species that lived in the West Texas-New Mexico area and developed only minor differences from the eastern populations. Within theT. naviatopotypic assemblage are specimens intermediate betweenT. naviaandT. pitcheri, and the eastern and westernT. pitcheriassemblages contain forms apparently transitional to two other species,T. washitaensisandT. belviderensis. Ecophenotypic variation in theT. pitcheriassemblages appears to be greater than that in European JurassicGryphaeaspecies and mirrors to some extent phyletic variation in European JurassicGryphaealineages.

Late Kinderhookian (Early Mississippian) Ammonoids of the Western United States

Ammonoid faunas of late Kinderhookian (Early Mississippian) age, virtually unknown previously in the American West, are described from several localities in New Mexico, Nevada, Utah, Idaho, and Montana. This study is based upon approximately 130 specimens from 33 collections. These specimens are variously assigned to at least 15 species in the following taxa: Protocanites, Imitoceras, Gattendorfia (Gattendorfia), Kazakhstania, Pericyclus (Goniocyclus), Rotopericyclus (Rotopericyclus), and R. (Hammatocyclus). The genus Muensteroceras, once widely regarded as appearing in the Kinderhookian, is unrepresented in these collections.The western faunas are characterized by the predominance of the pericyclids and relative scarcity of Imitoceras. Midcontinent faunas of the same age are characterized by the predominance of Imitoceras, scarcity of Pericyclus (Goniocyclus), and presence of Prodromites. Ammonoid faunas of early Osagean age differ in the presence of abundant Muensteroceras and rare Pericyclus (Pericyclus) and in the absence of Prodromites and Pericyclus (Goniocyclus).Most of the late Kinderhookian ammonoids, both in the West and in the Midcontinent, are assignable to the Siphonodella isosticha–Upper S. crenulata Conodont Zone of Sandberg et al. (1978). A few are referable to the Lower Siphonodella crenulata Zone of the same authors. No ammonoids have been described from equivalent beds in Europe which are included in the Siphonodella crenulata Zone of Voges (1960), despite the fact that Voges regarded this conodont zone as equivalent to the ammonoid Zone CuIIa of Schmidt (1925, p. 493). Based upon conodont correlations, the American Pericyclus (Goniocyclus) fauna is middle Tournaisian (Tn2b, c) in age and, with its Midcontinent equivalents, represents a part of the section between the Gattendorfia and the Pericyclus zones of Europe, from which ammonoids are as yet undescribed.One new subgenus is described in this paper: Pericyclus (Goniocyclus), its type species Goniatites blairi Miller and Gurley, 1896. New species described include Pericyclus (Goniocyclus) cooperi, P. (G.) costulatus, P. (G.) antelopensis, P. (G.) rockymontanus, P. (G.) filaris, P. (G.)? decipiens, Rotopericyclus (Rotopericyclus) pinyonensis, and R. (Hammatocyclus) brazerensis.

Distribution of Uranium in Middle Tertiary Volcanic Rocks, Mogollon-Datil Volcanic Field, New Mexico: ABSTRACT

The uranium abundances in middle Tertiary volcanic rocks of the Mogollon-Datil volcanic field, southwestern New Mexico, have been determined as part of a major petrogenetic study. Over 350 samples of middle Tertiary to Quaternary volcanic rocks have been analyzed for their uranium content by delayed neutron activation analysis. Of the volcanic associations previously proposed for southwestern New Mexico, calc-alkalic andesite, ±43 to ±35 m.y., has a mean of 2.3 ppm U (range 0.9 to 5.4 ppm); calc-alkalic quartz latite to rhyolite, ±35 to ±29 m.y., has a mean of 3.9 ppm U (range 1.7 to 6.2 ppm); basaltic andesite and associated rocks, ±32 to ±18 m.y., has a mean of 2.3 ppm U (range 0.8 to 6.9 ppm); and high-silica rhyolite, ±32 to ±18 m.y., has a mean of 5.2 ppm U (range 1.6 to 9.4 ppm). Anomalous values in the range of 14 to 35 ppm U were found for a riebeckite-bearing lava from the central San Mateo Mountains, a sample of intrusive andesite from the Alum Mountain area, and a lithophysal rhyolite lava and associated ash-flow tuff from the Sierra Cuchillo. Post-13-m.y. b omodal basalt-rhyolite is sparse within the Mogollon-Datil volcanic field. A few determinations from this study, and published and unpublished data for other localities in New Mexico, indicate U abundance from 0.3 to 1.5 ppm U in post-13-m.y. basalt and about 7 to 8 ppm U in rhyolite.

Coronadite; modes of occurrence and origin

The lead manganate, coronadite, was first recognized at the Coronado mine in the Morenci district, Arizona, by Lindgren in 1903. Several years later, the identity of the mineral was questioned and it was not until 1932 that Orcel recognized it in material from Morocco. Since 1955, the mineral has been recognized at numerous places; in the USSR, east of the Ural Mountains, in several districts in Morocco, England, Australia, and India. In recent years, coronadite had been identified at numerous localities in New Mexico, Arizona, Nevada, and California by the writer and others. At this time, it has been identified at 22 localities, and in the opinion of this writer, it will be found at many more places if it is sought for carefully.Author9s review of the known occurrences of coronadite and interpretation of the modes of geologic environment show that the mineral is found in veins and hot spring aprons, where it seems to have been deposited by hydrothermal waters from depth and that it is one of the manganese oxide minerals deposited as sediments. Probably it is more widely found in assemblages of minerals of supergene origin.

TWO PARAPATRIC SPECIES OF POCKET GOPHERS.

Pocket gophers are the most fossorial rodents in North America, where they occur from central Alberta to Panama. In areas where the ranges of two species meet, the distributional patterns are frequently unknown, although mapy authors have reported sharp dividing lines between ranges. The present study attempts to find why the observed distributions developed and how they are maintained. The major objectives were: (1) to compare the habitat preferences, territoriality, and reproductive cycles of Thomomys bottae and T. talpoides in areas where their ranges meet; (2) to study interspecific competition between these animals; and (3) to describe in detail the distributions of the species under study in selected areas. Although pocket gophers occupy habitats ranging from boreal to tropical, their morphology and mode of life vary little, and species are almost entirely allopatric or parapatric in distribution. Repeated mention of these distributional patterns has been made in the literature. Bailey (1931) found in many localities in New Mexico a hiatus between the ranges of T. fossor (= T. talpoides) and T. fulvus (= T. bottae) which was not occupied by pocket gophers. Bailey commented (1926) on the meeting of the ranges of T. talpoides and Geomys bursarius in North' Dakota, and thought that the larger, more aggressive Geomys occupied the more friable soils leaving the less desirable upland sites to T. talpoides. In Idaho, Davis (1939) found populations of T. townsendii which were isolated from each other and were within the range of T. talpoides. In Nevada both of these species were taken in the same field (Hall, 1946), although no overlapping of ranges was recorded. In his detailed study of the distributions of G. bursarius and G. personatus in southern Texas, Kennerly (1959) observed no overlapping of the ranges of these species and found only one locality where their ranges even met.

Epizootiology of Trypanosoma Cruzi in Southwestern North America1

Triatoma are reported infected with Trypanosoma cruzi Chagas from 18 new localities in Mexico and the United States. The invertebrate hosts and their localities are listed. The cimicids Hesperocimex coloradensis and H. sonorensis were both experimentally infected with T. cruzi .

Population Changes of Carnivores in Some Coyote-Control Areas

In 1940 and 1941 records were maintained of animals trapped during predator-control operations in seven localities in New Mexico, Colorado and Wyoming. Traps were set for coyotes, Canis latrans , and bobcats, Lynx rufus , but such animals as badgers, Taxidea taxus , skunks, Mephitis mephitis , raccoons, Procyon lotor , and swift foxes, Vulpes velox , were unavoidably trapped. The studies were repeated in 1951 and again in 1960, and the catch-records are used to indicate the population levels of the commonly trapped carnivores at the three 9–11-year intervals. It is recognized that variations in numbers of these animals probably occurred annually and that the catch-records reported here serve only as rough indicators of population status or trends. In four areas in Colorado and New Mexico, coyote numbers declined from 1940–41 to 1951, then increased in 1960. The population trends of bobcats, skunks and raccoons were generally in the reverse direction, with the largest catches in 1951. Badgers and swift foxes continued to increase over the 20-year period. In the three Wyoming areas, the coyote population dropped in 1960 to 8 per cent of its 1940–41 level while numbers of the other carnivores increased sharply. More than 25 times as many bobcats, 3 times as many skunks, and 8 times as many badgers were caught in this state in 1960 as 20 years ago; 9 raccoons also were trapped in 1960 where none was taken in 1940–41. There were changes in the population levels of coyotes and of some or all of the other carnivores during each of the 10-year periods in each of the three states. The causes of the changes in the numbers of other carnivores are obscure, but it is evident in each case that the level of coyote control which was applied did not hold down the populations of these other animals.

Fossil Bison and Associated Artifacts from Milnesand, New Mexico

Several Early man hunting sites have been discovered and excavated by various institutions in and near the High Plains region of Texas and New Mexico, including the Folsom, San Jon, and Clovis, or Blackwater Draw, localities in New Mexico, and the Miami, Plainview, Lipscomb, and Lubbock localities in Texas. To the west and north are similar sites in Arizona, Colorado, Nebraska, Wyoming, Montana, and the Dakotas. This large region, including a part of the great interior plains, was indeed for early man a big game hunting area of the North American continent.A new hunting site in this region, located in the southern part of Roosevelt County near Milnesand, New Mexico, about 40 miles south of Portales, is here described. This locality, containing artifacts, a bison-bone bed and charred bison bones, is in a sand-dune region about 3 miles northeast of Milnesand post office. (The name Milnesand is derived from “mill in the sand,” a term formerly applied to a windmill and watering place located near the present town.) The first artifacts obtained from the locality were collected by Ted Williamson of Milnesand.
