Monobasic Genus Research Articles

Grass-thrips of the genus Oelschlaegera (Thysanoptera: Thripidae), with the first description of a male.

The Chirothrips-like species are grass-living members of the Thysanoptera family Thripidae. All of these species were assigned to the genus Chirothrips Haliday (1836) until Hood (1954) erected Agrostothrips for a single species from South Africa, and Knechtel (1960) described a new monotypic genus Ereikethrips from Romania. An extensive identification key to the 52 species of Chirothrips then known was published by zur Strassen (1960), and the generic classification remained stable for the next 30 years. However, Bhatti (1990) erected five new genera for several species of this genus (Afrothripella, Arorathrips, Konothrips, Longothrips and Oelschlaegera). Bhatti also included three further species in Agrostothrips, but Minaei & Mound (2010) regarded Agrostothrips as a synonym, and returned all four species to Chirothrips. In the most recent study of the group, Nakahara & Foottit (2012) added one monobasic genus, Unilobothrips, and provided an identification system to the 36 Chirothrips-group species known from the Americas. Thus, eight genera are currently included in this genus group (Table 1).

Taxonomic and nomenclatorial revision within the Neotropical genera of the subtribe Odontocheilina W. Horn in a new sense—15. The genus Opisthencentrus W. Horn (Coleoptera: Cicindelidae)

The Neotropical, monobasic tiger beetle genus Opisthencentrus W. Horn, 1893, based on Oxygonia dentipennis Germar, 1843, is presented along with a lectotype designation. Most of the diagnostic characters of Opisthencentrus dentipennis (Germar, 1843), including the aedeagus and structures of the internal sac, are illustrated for the first time. Redescription and illustrations in colour photographs of the habitus and diagnostic characters of the female lectotype (MFNB) and five other specimens of both sexes are provided. The validity of Opisthencentrus as a separate genus is confirmed and it is concluded that the genus is a natural member of the subtribe Odontocheilina W. Horn, 1899, markedly differing from the genus Oxygonia Mannerheim, 1837. The history of the taxonomy and relationship to other genera of the subtribe, as well as the biology and distribution of this very rare and hitherto little known tiger beetle in the Brazilian Atlantic rain-forest, are discussed.

Chromosome Numbers and Basic Chromosome Numbers in Monocotyledonous Genera of the Western Himalayas (India)

Abstract Worldwide chromosome number information has been compiled from the literature for monocotyledonous genera whose members have been cytologically studied in the last three years from Kangra District (Himachal Pradesh) and Kashmir (Jammu & Kashmir) in the Western Himalayas, comprising 143 species of 86 genera in 12 families, many in the family Poaceae. Chromosome number information from the literature is supplemented with new and varied reports for 54 species/56 taxa from the present study. Overall, the chromosome numbers range from 2n=10 to 2n=120. Some species in all genera show a large number of cytotypes, clearly highlighting the role of inter- and intraspecific genetic diversity as well as polyploidy and dysploidy. The basic chromosome numbers in all 86 genera are reconsidered. Monobasic genera are more common in Poaceae, and polyba-sic genera are more common in the other 11 families. Polyploidy in the different genera ranges from 3x to 40x, and is quite high in certain genera (18x in Avena, Bothriochloa, Isachne, Helictotrichon and Panicum; 19x in Saccharum; 24x in Tradescantia; 28x in Eleocharis; 32x in Cyperus; 36x in Andropogon; 38x in Poa; 40x in Dioscorea). An updated checklist of chromosome number variability in these genera is given for India and world-wide.

The old-world Zygonini tr. nov. (Hemiptera, Cercopoidea, Clastopteridae), with new taxa from the related Machaerotinae.

Three new species of old-world Clastopteridae belonging to Machaerotinae are described, two in new monobasic genera: Allox transfigurata (Hindolini) from Borneo and Irridiculum deformatum (Machaerotini) from Sulawesi. One new species Machaeropsis dramatica (Hindolini) is described from Borneo. It is the first male known from the genus and shows that Machaeropsis Melichar is not synonymous with Metaenderleinia Lallemand. Five other new species are described, belonging to a new, related tribe Zygonini. Two of these new species (Ambonga lanceolata and Pseudomachaerota cucullata) belong to formerly monobasic genera from Madagascar incorrectly assigned to Cercopidae and Aphrophoridae respectively. These are related to 3 new genera: (1) from Madagascar, Pseudoclastoptera with new species P. irrubesco and P. invidia; from sub-Saharan Africa, (2) Zygon with 1 new species Z. desegregatum, and (3) Hemizygon, the latter with 2 new combinations from Pseudomachaerota: H. grande (Maa) and H. saturnus (Linnavuori). Zygon is possibly the most basal genus in Clastopteridae, according to its remarkable antennal characters with 5 different types of sensilla that show how basiconic and coeloconic sensilla are homodynamous. Genera related to Zygon are widely divergent from other spittlebugs as measured by mDNA "barcode" data from the COI gene.

Redescription of aquatic grass inhabiting Frankliniella zizaniophila (Thripidae: Thripinae) with remarks on its systematic position within the genus Frankliniella (Thysanoptera).

The aquatic grass-inhabiting thrip, Frankliniella zizaniophila (Han & Zhang 1982) (Thripidae: Thripinae), is redescribed and illustrated, and the larvae and the yellow color type of this species are described for the first time. Judging from its unique morphological characters and host plant, the systematic position of this species in Frankliniella is questionable, but until the thrips fauna of Asia is better explored, it seems best to leave this species in Frankliniella , rather than to erect a new monobasic genus.

Description of a New Leafhopper Genus and Species of Megophthalminae (Hemiptera, Auchenorrhyncha, Cicadellidae) from Southern China

Abstract A new monobasic leafhopper genus and species of the tribe Agalliini (Hemiptera: Auchenorrhyncha, Cicadellidae: Megophthalminae), Multinervis guangxiensis Li and Li, new genus and new species, is described and illustrated from Guangxi in Southern China. Multinervis appears to be closely related to three Southeast Asian genera, Dryodurgades Zakhvatkin 1946, Paulagallia Viraktamath, 2011 in reticular venation on forewings and Sangeeta Viraktamath, 2011 in upper striations at face, but can be distinguished mainly by the unique characters of the male genitalia and the structure of external morphology.

Two new genera of mites of the family Hypoderatidae (Acari: Astigmata) from swifts and their nests (Apodiformes: Apodidae) from the Philippines

Two new monobasic genera of the family Hypoderatidae are described from the Glossy Swiftlet Collocalia esculenta (Linnaeus) and its nests: Apodidectes gen. nov. with the type species Apodidectes verrucosus sp. nov. and Collocalidectes gen. nov. with the type species Acarus collocaliae Bernstein, 1857. The description of Ap. verrucosus includes descriptions of all stages of the life cycle. For Collocalidectes collocaliae, previously known from only the heteromorph deutonymph (hypopus), adults and tritonymph are described for the first time. The two new genera constitute a peculiar group within Hypoderatidae by having a unique structure of proral setae in adults. In contrast to other hypoderatid genera having claw‐like proral setae, in Apodidectes and Collocalidectes, these setae are very thin, slightly flattened (i.e. similar in structure to unguinal setae of the same tarsi) and tightly pressed to the ventral surface of the ambulacral stalk. Morphological peculiarities of the genera Apodidectes and Collocalidectes and ontogenetic changes of idiosomal and leg chaetotaxy in Ap. verrucosus are discussed. The genus Colobathriglyphus Fain and Nadchatram, 1983 is formally transferred to the Hypoderatidae from the Acaridae, and the subfamily Colobathriglyphinae syn. nov. is placed in synonymy with Hypoderatinae. http://zoobank.org/urn:lsid:zoobank.org:pub:05795E84-D62A-40F5-AB8B-483CFB271F64

A new genus and species of Agalliini from China (Hemiptera, Cicadellidae, Megophthalminae)

A new monobasic genus and species of the tribe Agalliini (Hemiptera: Cicadellidae: Megophthalminae) from Guizhou province of China is described and illustrated. Spinoagallia gen. nov. accommodates S. freytagi sp. nov.. The new species can be distinguished mainly by the unique characters of the male genitalia, combining the macrosetae on the outward and spine-like process curved ventrally on the inward pygofer caudodorsal lobe. A key for identification to new genus based on modifying primal key by Viraktamath (2011) is given. A map showing the geographic distribution of the new species is also provided.

Two new species of the apterous Carventinae genus Comorocoris Heiss, 1985 from Madagascar (Hemiptera: Heteroptera: Aradidae)

The monobasic genus Comorocoris Heiss, 1985 was erected for the peculiar apterous species C. testudiformis fromMoheli Island [= Mwali] of the Comoro Archipelago. Recent forest litter sifting in Madagascar unexpectedly brought to light two new species belonging to this genus which are described and illustrated. A key to the three species is given.

Review of the millipede genus Hyleoglomeris Verhoeff, 1910 in China, with descriptions of new species (Diplopoda, Glomerida, Glomeridae)

China is shown to currently support 23 species of the large, basically warm temperate to tropical Asian genus Hyleoglomeris,all keyed and mapped, including 15 new ones: H. tiani sp. n., H. xia sp. n. and H. youhao sp. n. from Hunan Province, H. wusesp. n., H. nigu sp. n., H. gudu sp. n. and H. yinshi sp. n. from Guizhou Province, as well as H. qiyi sp. n., H. lii sp. n., H.heshang sp. n., H. xueju sp. n., H. mulunensis sp. n., H. mashanorum sp. n., H. curtisulcata sp. n. and H. kunnan sp. n. fromGuangxi Province. Hyleoglomeris eusulcata Golovatch, Geoffroy & Mauriès, 2006 has been recorded and redescribed from anew, near-topotype sample. Two new species groups are being proposed: the venustula- and the albicorporis-group. The statusof Nearctomeris Wesener, 2012, a monobasic genus from the eastern USA, is questioned viz-à-viz Hyleoglomeris, albeit no formal synonymy is being proposed.

Revision of the Australian bee genus Trichocolletes Cockerell (Hymenoptera: Colletidae: Paracolletini)

The monobasic genus Trichocolletes (Cockerell, 1912) was erected for the species Lamprocolletes venustus Smith by virtue of its conspicuously hairy eyes. Rayment (1929, 1931) added four additional species so that Cockerell’s 1934 survey of the family Colletidae in Australia, listed five names in the genus Trichocolletes. When Michener (1965) revised the genera of Australian bees, he recognized that species without hairy eyes, previously placed in Anthoglossa and Paracolletes, belonged in a more broadly defined genus. At the same time Michener created a separate subgenus for the species T. pulcherrimus Michener, a decision he recently suggested (Michener, 2007) might merit reexamination. Since 1965, two new species have been added (Houston, 1990), but there has been no revision of the genus. This is, therefore, the first species-level revision of the genus Trichocolletes. A recent molecular phylogeny of the family Colletidae (Almeida & Danforth, 2009) concluded that the Australian and South American genera traditionally included in the tribe Paracolletini (Michener, 2007), excluding Callomelitta and Paracolletes s. str., form a monophyletic group and it has been proposed (Almeida et al., 2012) that the name Neopasiphaeinae should be used for this group. The phylogenetic analysis suggested that the genus Anthoglossa is sister to all other Neopasiphaeinae and the genus Trichocolletes is, in turn, sister to all Neopasiphaeinae other than Anthoglossa. Until morphological clarification of the status of Paracolletes is available, we have opted to follow Michener’s (2007) family-level names. aBstract. The endemic Australian bee genus Trichocolletes is revised. Forty species are recognised, including twenty-three new species: Trichocolletes aeratus, T. albigenae, T. avialis, T. brachytomus, T. brunilabrum, T. capillosus, T. centralis, T. dundasensis, T. fuscus, T. gelasinus, T. grandis, T. lacaris, T. leucogenys, T. luteorufus, T. macrognathus, T. micans, T. nitens, T. orientalis, T. platyprosopis, T. serotinus, T. simus, T. soror and T. tuberatus. Four new synonymies are proposed: Paracolletes marginatus lucidus Cockerell, 1929 = T. chrysostomus (Cockerell, 1929); T. daviesiae Rayment, 1931 = T. venustus (Smith, 1862); T. marginatulus Michener, 1965 = T. sericeus (Smith, 1862); T. nigroclypeatus Rayment, 1929 = T. venustus (Smith, 1862). Trichocolletes rufus (Rayment, 1930) is moved to Leioproctus and T. rufopilosus (Rayment, 1935) to Anthoglossa. Descriptions are given for new species and redescriptions for species described before 1965, including first descriptions of males of T. aureotinctus (Cockerell), T. burnsi Michener, T. latifrons (Cockerell) and T. maximus (Cockerell) and the females of T. dowerinensis Rayment and T. rufibasis (Cockerell). Lectotypes are designated for Lamprocolletes venustus Smith and Anthoglossa plumata Smith. Keys to species are provided for both sexes, as are distribution maps and a summary of recorded floral visitation.

Indophyes yaromi, a new genus and species of Nanophyidae (Curculionoidea) from southern India

A new monobasic genus of Nanophyidae, Indophyes, and a new species, I. yaromi, are described from southern India (type locality: Karnataka, Bilukoppa, 800 m, 40 km W Mudigere). The new genus is characterized by 5-segmented antennal funicle, strong sexual dimorphism of the rostrum, dentate femora, male tibiae unarmed, abdominal suture IV distinct in both sexes, male pygidium not foveate and 8th elytral interstria not crenulate. The subulate form of rostrum—abruptly narrowed apically—is unusual among the Nanophyidae.

New Hystricognathous Rodents from the Early Oligocene of Central Libya (Zallah Oasis, Sahara Desert): Systematic, Phylogenetic, and Biochronologic Implications

ABSTRACT Four fossil rodent taxa are described from a new locality in the Oligocene Continental and Transitional Marine Deposits outcropping in the vicinity of Zallah, Sirt Basin, central Libya. These rodents belong to the infraorder Hystricognathi Tullberg, 1899, and are distributed amongst four genera (Metaphiomys Osborn, 1908; Phiocricetomys Wood, 1968; Talahphiomys Jaeger et al., 2010; and Neophiomys , new genus) that include one new species, Phiocricetomys atavus, and one new combination, Neophiomys paraphiomyoides (Wood, 1968), formerly Phiomys paraphiomyoides Wood, 1968. The specimens described here have profound implications for the phylogenetic and systematic status of early hystricognathous rodents and paleogeographical debates regarding their origin. Based on a cladistic analysis, Waslamys attiai Sallam et al, 2009, is transferred to the genus Protophiomys Jaeger et al., 1985, as Protophiomys attiai (Sallam et al, 2009), new combination. That species is the type species of the monobasic genus W...

Male terminalia and undescribed female of Ceratoplatus fullerae Schmitz (Diptera: Phoridae) from New Zealand

The male terminalia and previously undescribed female of Ceratoplatus fullerae Schmitz, known only from New Zealand, is described. The monobasic genus Ceratoplatus Schmitz is confirmed to belong in the Hypocerinae (sensu Brown 1992), and its identification is clarified within the latest key to world genera (Disney 1994).

Notes on quill mites (Acariformes, Syringophilidae) from aquatic birds in North America

AbstractA new monobasic genus of parasitic mites, Phalarophilus fulicarius gen. nov., sp. nov. (Acariformes, Syringophilidae) is described from feather quills of Phalaropus fulicarius (Linnaeus) (Charadriiformes, Scolopacidae) from USA. Females of the new genus differs from those of the genus Bochkovia Skoracki et OConnor, by having the rounded posteriorly stylophore, edentate movable cheliceral digits, propodonotal setae arranged 2-1-1-2, thin and smooth dorsal setae of the idiosoma, smooth dorsal setae of legs I and II, and by the presence of setae vsI; males are distinguished by the presence of the propodonotal setae arranged 2-1-1-1-1. Additionally, two new syringophilid species recorded from aquatic birds in North America and three new host associations of these mites are recovered.

New cricket taxa of the subfamilies Phaloriinae and Pteroplistinae (Orthoptera: Gryllidae) from South-East Asia

Four new species of Phaloriinae (Trellius barisan sp. nov, T. lampung sp. nov., T. curup sp. nov., and T. inquisitor sp. nov.) and a new monobasic genus of Pteroplistinae (Asymmetriola spinosa gen. et sp. nov.) are described. T. inquisitor is from Central Vietnam and the other crickets are from Southern Sumatra, Indonesia.

Calliscelio elegans (Perkins), a tramp species, and a review of the status of the genus Caenoteleia Kieffer (Hymenoptera: Platygastridae)

The monobasic genus Caenoteleia Kieffer (Hymenoptera: Platygastridae) is considered to be a junior synonym of the widespread and common genus Calliscelio Ashmead, new synonymy. Calliscelio elegans (Perkins) is redescribed, transferred to Calliscelio, new combination, and its geographic distribution documented. Originally described from Hawai‘i, this species is widespread through the tropics. The species likely is distributed by human commerce, possibly in association with cricket pests (Orthoptera: Gryllidae) of sugar cane.

Dioptine Moths of the Caribbean Region: Description of Two New Genera with Notes on Biology and Biogeography (Lepidoptera: Notodontidae: Dioptinae)

ABSTRACT Two new species of dioptine moths (Lepidoptera: Noctuoidea: Notodontidae: Dioptinae) are described from the Caribbean island of Hispaniola, and placed in two new monobasic genera. These are the first records of subfamily Dioptinae in the Caribbean Region. Eremonidia mirifica new genus, new species, is a plesiotypic member of the tribe Dioptini, and Caribojosia youngi new genus, new species, is placed in the tribe Josiini. Both species are described from cloud forest habitats in the Sierra de Neiba (Dominican Republic and adjacent Haiti); E. mirifica is also known from similar habitats in the Cordillera Central (Dominican Republic). The larvae of C. youngi are described feeding on mature leaves of Passiflora sexflora Jussieu (Violales: Passifloraceae). Habitats, relationships, ecological associations, behavior, and conservation issues for these species are discussed.

A new genus of Oedemopsini (Hymenoptera: Ichneumonidae: Tryphoninae) with a key to the genera of the tribe

AbstractScudderopsisgen. nov. is described from New Guinea (type species: Scudderopsis baiyerensissp. nov.). This monobasic genus is placed in the tribe Oedemopsini. A diagnosis and key are provided to distinguish Scudderopsis from the other 11 genera in the tribe.

Reevaluation of the Phylogeny of the Ephemeroptera Infraorder Pannota (Furcatergalia), with Adjustments to Higher Classification

Abstract Phylogeny of the cosmopolitan Ephemeroptera infraorder Pannota (Furcatergalia) is revised based on analysis of 46 characters from 34 Operational Taxonomic Units under the parsimony criterion of PAUP*, with Rhoenanthus Eaton (Scapphodonta: Potamanthidae) as an outgroup. Phylogenetic sequencing conventions were applied to the most parsimonious tree that was derived from this analysis. The resultant changes in classification include placing Philolimnias Hong, a monobasic genus from Eocene amber, into Philolimniidae, n. fam. Vietnamellidae is restricted to include only Vietnamella Tshernova, and Austremerella Riek is replaced in Austremerellidae, revalidation. Teloganella Ulmer is moved to Melanemerellidae (subfamily Teloganellinae, n. stat.). Coryphorus Peters is returned to Leptohyphidae (subfamily Coryphorinae, n. stat.).
