Description of three new species of frog–biting midges (Diptera: Corethrellidae) from the Central Brazilian Amazon

Three species of Corethrella Coquillett, 1902 from the state of Amazonas, Brazil are described as new to science based on female adult specimens. Corethrella cabocla Feijó, Belchior, Marialva & Pessoa sp. nov. possesses four large setae on the frons between the ventromedial area of ommatidia, a wide clypeus with 1–4 setae, a wing with the apex of R2 basal to the apex of M2 and with a midlength band, and with the abdomen entirely dark brown. Corethrella ielemdei Feijó, Ramires, Lima & Pessoa sp. nov. possesses an elongated coronal suture, four large setae on the frons between the ventromedial area of ommatidia, a clypeus squarish with 42–43 setae, a wing with the apex of R2 basal to the apex of M1 and with a midlength band and dark scales on the basal and subbasal areas of the anterior margin, legs with dark scales, and with the abdomen entirely dark brown. Corethrella menini Feijó, Picelli, Ríos-Velásquez & Pessoa sp. nov. possesses wings with the apex of R2 basal to the apex of M2 and a midlength band, with darker basal scales along all veins, basal band dark scales on C, Sc, R, M, and Cu and the abdomen entirely dark brown. With the addition of the new species, the numbers of frog-biting midges described in the Amazon basin, Brazil and in Neotropical region are now 31, 49 and 80 species, respectively.

Reevaluation of species richness in Winnertzia (Diptera, Cecidomyiidae, Winnertziinae), with descriptions of 37 new species from Sweden, Peru and Australia

Tentative studies of Malaise trap samples from different geographic regions and habitats indicate unanimously that Winnertzia, a genus of mycophagous gall midges (Cecidomyiidae), is exceptionally speciose, but hard data in proof of that were previously unavailable. A taxonomic inventory of mycophagous cecidomyiids in Sweden has now revealed that, of 751 species found in total, 93 are Winnertzia. A preliminary census in 2013 had identified only 26 different Winnertzia in Sweden. Two factors are responsible for this increment: the inclusion of large amounts of fresh material to study and the application of a narrower species concept. The latter results from the reevaluation of male morphological characters in the light of COI sequence (DNA barcoding) data. With the inclusion of 37 new Winnertzia described here, the genus now contains 136 extant species. New Winnertzia discovered in Sweden are described here under the following names: W. acutistylus sp. nov., W. angustistylus sp. nov., W. arctostylus sp. nov., W. bicolor sp. nov., W. brachytarsus sp. nov., W. dentata sp. nov., W. egregia sp. nov., W. ekdalensis sp. nov., W. fraxinophila sp. nov., W. grytsjoenensis sp. nov., W. hamatula sp. nov., W. hemisphaerica sp. nov., W. imbecilla sp. nov., W. incisa sp. nov., W. inornata sp. nov., W. lapponica sp. nov., W. lobata sp. nov., W. longicoxa sp. nov., W. normalis sp. nov., W. oelandica sp. nov., W. ombergensis sp. nov., W. parvidens sp. nov., W. pilosistylus sp. nov., W. pratensis sp. nov., W. pustulatula sp. nov., W. quercinophila sp. nov., W. rickebasta sp. nov., W. ruliki sp. nov., W. serri sp. nov., W. setosa sp. nov., W. silvestris sp. nov., W. smalandensis sp. nov., W. sundini sp. nov., W. tumidoides sp. nov., and W. upplandensis sp. nov. Additionally, W. panguana sp. nov. is the first Winnertzia described from the Neotropical region (Peru), and W. warraensis sp. nov. is the first member of the genus described from the Australasian region (Tasmania). Parwinnertzia Felt, 1920 syn. nov. is revealed to be a junior synonym of Winnertzia Rondani, 1860, implying the recombinations of Winnertzia notmani (Felt) comb. nov. and Winnertzia italiana (Mamaev Zaitzev) comb. nov. The intrageneric classification of Winnertzia is reviewed and developed further, with the W. setosa group introduced for species whose gonostylar claw is conspicuously long and exposed, and whose gonocoxal emargination is bordered by dense, large setae. Winnertzia feralis Mamaev, revived here from synonymy with W. tridens Panelius, and W. fusca Kieffer are new faunistic records in Sweden. Swedish records published in the past of W. brachypalpa Mamaev and W. pravdini Mamaeva Mamaev rest on misidentifications, and both species are deleted from the Swedish checklist.

Two new species of the genus Curranosia Paterson, 1957 (Diptera: Muscidae) from the Afrotropical Region

Curranosia vanemdeni spec. nov. is described from Kenya. The species is characterized by features such as protruding mouthparts, slender proboscis and an anterior seta on mid tibia, which were not previously known to occur in this genus. Curranosia wyatti spec. nov., collected in The Gambia differs from other Curranosia species by wing colour, absence of white dusted markings on the presutural mesonotum, and differences in the numbers of large setae of the body, characters that are more common for the differentiation of species of the genus.

Phylogeny of the genus Fuscoporia and taxonomic assessment of the F. contigua group

ABSTRACTThe genus Fuscoporia of the Hymenochaetaceae is characterized by resupinate to pileate basidiocarps, a dimitic hyphal system with fine crystal aggregates and encrusted generative hyphae in dissepiment edge and tube trama, the presence of hymenial setae, and hyaline, thin-walled, smooth basidiospores. Members of the F. contigua group are easy to distinguish from other species of Fuscoporia because of the moderately large pores, presence of mycelial setae, and large hymenial setae. Here, we explore phylogenetic relationships among 20 species of Fuscoporia based on examination of some 90 collections sampled worldwide. Seven new species are recognized in the F. contigua group—F. americana, F. centroamericana, F. costaricana, F. latispora, F. monticola, F. septiseta, and F. sinica—described from China, Costa Rica, Mexico, and the United States. Phylogenetic analyses inferred from DNA sequences of the nuc rDNA internal transcribed spacer (ITS1-5.8S-ITS2 = ITS), D1–D2 domains of nuc 28S rDNA (28S), and translation elongation factor EF-1 alpha (tef1) support the F. contigua group as one of two major clades within Fuscoporia comprising nine species worldwide.

Cirolana bambang, a distinctive new species of Cirolana Leach, 1818 (Crustacea: Isopoda: Cirolanidae) from Bitung, Indonesia

Cirolana bambang sp. nov. from Bitung, North Sulawesi, Indonesia is described. The species can be recognised by generally smooth body with small, acute, submedian nodules on pleonites 4-5 and the anterior dorsal surface of the pleotelson together with a flat, pentagonal frontal lamina, linguiform and sexually dimorphic pleotelson with the dorsal surface covered by short setae in males, deeply bifid uropod apices, and a conspicuously large robust seta on the superodistal angle of pereopod 1 ischium. Cirolana bambang sp. nov. appears to belong to a group of Indo-West Pacific Cirolana with prominent penial process, a large robust seta on the superodistal angle of pereopod 1 ischium and the presence of setae on dorsal surface of pleotelson and or uropod in males. The most similar species are Cirolana comata Keable, 2001; Cirolana dissimilis Keable, 2001; Cirolana aldabrensis Schotte Kensley, 2005; and Cirolana somalia Schotte Kensley, 2005. Cirolana kiliani Müller, 1993 and C. somalia are found not to belong to the Cirolana'parva-group'.

A new species of the genus Apseudomorpha Miller (Crustacea, Peracarida, Tanaidacea) from Korea

A new species of Tanaidacea is described from the eastern coast of Korea, under the name of Apseudomorpha magna in the family Metapseudidae. The new species can be distinguished from its congeners by the following combination of characters: pleonites 2 and 5 and pleotelson have a large lateral seta; pleopods are biramous, in five pairs, each bearing a two-segmented exopod and a single-segmented endopod; the maxillular palp is two-segmented, with five setae on its distal segment; the pleotelson has a large seta on each anterolateral process; and the mandibular palp has 2, 7, and 13 setae on the first to third segments, respectively.

First record of the endemic Neotropical genus Hyphydrophilus (Chilopoda: Geophilomorpha, Geophilidae) from Argentina, with description of H. minellii sp. nov., a new centipede with small tentorial process, inhabiting the Yungas

ABSTRACTA new miniature species of the endemic Neotropical genus Hyphydrophilus (Chilopoda: Geophilomorpha, Geophilidae) is described and illustrated, after the holotype female and paratype female, from the Yungas rainforest of Salta province, northwestern Argentina. H. minellii sp. nov. is compared in detail with the other two species currently assigned to the taxon, i.e. H. adisi Pereira, Minelli & Barbieri, 1994 and H. projectus Pereira, Foddai & Minelli, 2000, both from Brazil, from which it differs by the presence of a small slightly sclerotized and inwards directed process of internal limbs of tentorium. Other unique traits of the new taxon are the relatively high number of leg-bearing segments (59), antennal articles I–IV with numerous large setae on the latero-external side, apical medial edge of forcipular trochanteroprefemur with a well-developed slightly pigmented tooth, dorsal and ventral medial edges of the forcipular tarsungulum slightly serrate, sternal pore-fields present on anterior region of the trunk only. This is the first report of the genus Hyphydrophilus from Argentina and the Yungas forests; previously it was only known to occur in Central Brazilian Amazonia, thus the present record represents a remarkable extension of the known range of this taxon.

Interspecific variation in ovipositor morphology among Manaosbiid and Nomoclastid Harvestmen (Arachnida, Opiliones, Laniatores)

The external anatomy of the ovipositor has generally been overlooked as a source of informative characters in systematic studies of laniatorean harvestmen. In this study, we used scanning electron microscopy to examine the ovipositors of nine species representing the families Manaosbiidae (five species) and Nomoclastidae (four species). Similar to the ovipositor morphology of many gonyleptoidean families, the distal tips of the ovipositors of these harvestmen have four external lobes, with the margins most commonly adorned with 10 large peripheral setae. In manaosbiid and nomoclastid species, these peripheral setae have undivided bases, striated shafts and undivided distal tips. There are typically three setae on each anterior lobe and two setae on each posterior lobe. The medial setae on both anterior and posterior lobes insert into sockets that are slightly more dorsal. We observed small, surface denticles, usually associated with a pore, on the external surface of the lobes. There was interspecific and intraspecific variation in the number and shape of these surface denticles. The association of pores with denticles on the ovipositor appears to be a feature common to not only both families but is also a trait that has not been observed on ovipositors in other families of laniatorean harvestmen.

Nothoaspis reddelli Keirans & Clifford, 1975 (Acari, Ixodida, Argasidae): distribution extension

The first record of Nothoaspis reddelli (nymph) in Nicaragua is presented. The morphological characters used for the determination were dorsum with a false shield or nothoaspis, presence of an anteriorly projecting hood covering half of the capitulum, medial extension of palpal article I (flaps), presence of two large setae on internal margins of flaps, leg coxae with numerous long setae, and hypostome long and pointed with apical dentition 4/4. The 16S rDNA sequence of N. reddelli from Nicaragua was identical to the 16S sequence of N. reddelli from Mexico.

Haromyia, a new genus of long-legged flies from Dominica (Diptera: Dolichopodidae).

The new micro-dolichopodid genus Haromyia gen. nov. and the type species H. iviei sp. nov. are described from the island of Dominica in the Lesser Antilles. Males and females of Haromyia are distinguished by the large setae on a bulging clypeus, minute size, and wing veins that are nearly straight and evenly diverging from wing base. Haromyia does not fit readily into any contemporary dolichopodid subfamily, although it superficially resembles the Enliniinae and Achalcinae. Haromyia should be regarded as incertae sedis until the dolichopodid subfamilies can be refined, particularly to better incorporate the tropical diversity of this large family.

Epipharyngeal Morphology in Hyperini Larvae (Coleoptera, Curculionidae, Hyperinae)

Abstract Investigation of the main epipharyngeal structures in representatives of Hyperini weevils larvae has shown that in general case 6 als, 2 (4) ams, 4 mes and 2 snp present: Coniatus (Bagoides) splendidulus (Fabricius, 1781) - 6 als, 2 ams, ?1 mes, 2 x 3 snp, Donus bucovinensis (Penecke, 1928) - 6 als, 2 ams, 4 mes, 2 x 5 snp, D. geminus (Zaslavskij, 1967) - 6 als, 2 ams, 4 mes, 2 x 5 snp, Hypera (Eririnomorphus) rumicis (Linnaeus, 1758) - 6 als, ?4 ams, 4 mes, 2 x 2 snp, H. (Hypera) miles (Paykull, 1792) - 6 als, ?4 ams, 4 mes, 2 x (4-5) snp, H. (H.) transsylvanica (Petri, 1901) - 6 als, 2 ams, 4 mes, 2 x (3-5) snp, Limobius borealis (Paykull, 1792) - 6 als, 2 ams, 4 mes, 2 x 4 snp. By morphological peculiarities of epipharyngeal surface the studied larvae can be divided into next 4 groups: 1) epipharynx with wide flat areas, short setae and shallow emargination (C. splendidulus); 2) with wide flat areas, medium-sized setae, strait and sharp excision on anterior margin (D. bucovinensis, D. geminus); 3) with short flat areas, medium to long setae and wide apical emargination (H. miles, H. rumicis, H. transsylvanica); 4) with uneven surface, large long setae and short emargination (L. borealis). It is supposed that morphological peculiarities of ephiphaynx in Hyperini relate to type of feeding.

Three new Peruvian species ofProtimesius(Opiliones: Laniatores: Stygnidae)

Three new species of the harvestmen genus Protimesius Roewer 1913 are described from the Amazonian region of Peru. Protimesius amigos n. sp. from Madre de Dios Department may be distinguished by the absence of an anterior prominence on the prosoma and the presence of five pairs of basal large setae on the penis. Protimesius machiguenga n. sp. and P. kakinte n. sp. are described from the Lower Urubamba region of Cusco Department; P. machiguenga n. sp. is similar to P. cirio Villarreal-Manzanilla & Pinto-da-Rocha 2006 and can be distinguished from it by the presence of a conspicuous dorsal prolateral row of tubercles on the male tibia IV; P. kakinte n. sp. is similar to P. amphichelis Roewer 1931 and P. boibumba Villarreal-Manzanilla & Pinto-da-Rocha 2006, but can be separated from these by the development of tubercles on the femur and tibia IV, and by the number of retrolateral tubercles on male femur IV. New records of P. albilineatus (Roewer 1957) from Loreto department in northern Peru are also reported.

Deux nouvelles espèces deDasypsyllus(Siphonaptera : Ceratophyllidae) au Chili

New taxa, known only by the male, are added to chilio-andean fauna. These fleas belong to sub-genus Neornipsyllus, parasites of Birds, essentially "Passeriforms". D. (N.) huinayensis sp. n. is, inter alia, characterized by the place of large setae on telomere; D. (N.) tapaculensis sp. n. show a tergit XI (or proctiger) unusual for the entire Order by the form and the chaetotaxy composed, essentially, of forked setae.

A new species of Aphis (Hemiptera: Aphididae) living on roots of Thymus mastichina (Lamiaceae) from Spain

Apterous females (fundatrices and fundatrigeniae), alatae females, oviparous females and males of Aphis mastichinae nov. sp. from Thymus mastichina (Lamiaceae) are described. It is the only known species of the genus Aphis which is radicicolous on Lamiaceae. It is mainly characterized by the short siphunculi, large and numerous abdominal marginal papillae and short setae. A key for the Aphis species living on Thymus species is given.

Separation of Leydigia louisi Jenkin, 1934 from L. leydigi (Schoedler, 1863) (Chydoridae, Anomopoda, Cladocera)

The aim of the present article was to contribute to the systematics of the leydigi-like species of Leydigia consisting of a few (probably 3) formal species with: (1) a large basal spine on the postabdominal claw (as long as claw thickness at the base); (2) a short setulation at anterior margin of labral keel; (3) no longitudinal striation on the female valves; (4) at least three lateral setae in each fascicle on the postabdomen; (5) three large lateral setae on exopodite III. The morphology of L. leydigi (Schoedler, 1863) and L. louisi Jenkin, 1934 are redescribed, and type material of L. macrodonta Sars, 1916 is studied. In contrast to previous suggestions (Jenkin, 1934; Smirnov, 1971), I found that: (1) L. louisi is a valid species, not a subspecies of L. macrodonta; (2) L. macrodonta is not a member of the L. leydigi-group. The third member of leydigi-group, Leydigia macrodonta longiseta Chen Shou-zhong, 1992, was described from China. It is not a subspecies of L. macrodonta, but a relative of L. leydigi; most probably, it is a valid species, but this opinion must to be confirmed by examination of original Asian material. In this article, the presence of L. leydigi in Palearctic only, and that of L. louisi in only Africa was confirmed. A new subspecies of L. louisi, found in Mexico, will be reported separately.

Copepoda associated with the thorny coralAntipathes(Antipatharia) in the Indo-Pacific

Six new copepods are associated with five species of the antipatharian coral Antipathes in the Indo-Pacific. Three asterocherid siphonostomatoids are described. Asteropontius latus sp. nov., from Antipathes sp. at Bohol Island, Philippines, has an unusually broad prosome. Asteropontius bandicola sp. nov., from Antipathes abies (L.) in the Moluccas and Antipathes cf. spinescens Gray in northwestern Madagascar, has rounded lateral margins on the female genital somite and the free segment of leg 5 is elongate with the ratio 2·69:1. Orecturus grandisetiger gen. nov., sp. nov., from Antipathes ericoides Pallas and Antipathes longibrachiata (van Pesch) in northwestern Madagascar, Antipathes reticulata Esper in the Moluccas, and Antipathes sp. at Bohol, Phillipines, has an unusually large seta on the third segment of the first antenna. Three lichomolgid poecilostomatoids are described from Antipathes sp. at Bohol in the Philippines. Visayasia lobura gen. nov., sp. nov., and Visayasia subterna gen. nov., sp. nov., are characterized by having the third segment of the endopod of leg 1 in both sexes armed with I, I, 4. Paramolgus delicatulus sp. nov., has a short caudal ramus and the female genital double somite is indented. The range of Paramolgus insectus (Humes, 1969) is extended from Madagascar and the Moluccas to the Philippines.

Relationship between mouthpart structures and in situ feeding habits of species of the family Pontellidae (Copepoda: Calanoida)

Pontellid copepods were collected from the surface waters of a tidal front region in the Bungo Channel (the Inland Sea of Japan) in June 1986 to examine the relationship between the morphology of cephalic appendages and gut contents. In particular, two dominant species,Labidocera japonica Mori andPontellopsis yamadae Mori, were compared in detail. Large setae on the second maxillae ofL. japonica possessed two rows of setules at right angles to each seta along its inner margin except a terminal part which was serrated, whereas the inner margin of those setae ofP. yamadae was entirely serrated. Judging from the structure of the mouthparts, especially the second maxillae, the former species seems to employ both suspension and raptorial feeding modes, in contrast to the latter, which may use only the raptorial mode of feeding. InP. yamadae, the first maxilla and the maxilliped are also modified for carnivory. Gut content analysis supported the morphological evidence for feeding differences, and revealed thatP. yamadae is a carnivore preying mainly on copepodids whileL. japonica feeds omnivorously on copepod nauplii and phytoplankton particles. Since the mouthpart structures of congeners are quite similar to each other, the feeding behavior and habits might also be similar. Within the family Pontellidae, the generaAnomalocera, Calanopia, Epilabidocera, andPontella have mouthpart structures similar to those ofLabidocera, whereas the genusPontellina resemblesPontellopsis. Morphological similarities would suggest that the first group of genera employs both suspension and raptorial feeding modes, and thatPontellina is a carnivore likePontellopsis.

Structure of the cuticle of the alpine weta, Hemideina maori (Saussure) (Orthoptera: Stenopelmatidae)

Sclerotized cuticle segments from the thorax, dorsal abdomen, and ventral abdomen of the alpine, weta Hemideina maori (Saussure) (Orthoptera: Stenopelmatidae) were examined by light microscopy and by scanning and transmission electron microscopy. An epicuticle, exocuticle (outer and inner), mesocuticle, endocuticle, and deposition layer are present in transverse sections. The epicuticle is further composed of a cuticulin layer and inner epicuticle, the latter being finely laminated and containing narrow wax canals that terminate below the cuticle surface. Openings to dermal gland ducts are visible on the surface as are large setae and smaller sensory pegs. Frozen fractured cuticle reveals the presence of horizontal ducts or channels that run laterally within the cuticle. The structure of weta cuticle is compared with that of the common house cricket and arthropods in general.

THE EGGS AND LARVAE OF CRYPTOCEPHALUS QUADRUPLEX NEWMAN AND C. VENUSTUS FABRICIUS, WITH A KEY TO THE KNOWN IMMATURE STAGES OF THE NEARCTIC GENERA OF CRYPTOCEPHALINE LEAF BEETLES (COLEOPTERA: CHRYSOMELIDAE)

AbstractThe eggs and larvae of Cryptocephalus quadruplex Newman and C. venustus Fabricius are described and illustrated. Both species very likely overwinter in the larval stage. The adults emerge from the last week of May to mid-June. Before mating they feed on plants for about a week. The oviposition period is quite extended and lasts from mid-June to the end of July. The eggs are laid singly in the leaf litter. The hatching period was 10–15 days in the laboratory. The larvae develop through 5 instars and feed exclusively on dead or decaying leaves of various plants. By the end of September most of them have grown to the 4th instar, some to the 5th. At this moment they stop feeding and move deeper in the leaf litter for overwintering. The 1st instar is easily recognized by the presence of the egg bursters on meso- and metathorax, the large flattened-papillate setae of the head capsule, and the presence of 2 pairs of spiniform setae on tibiae. In the following instars the size varies as well as the number of spiniform setae on the tibiae and the number of secondary clubbed setae on the pronotum.
