Armatalona gen. n. – a new genus of subfamily Aloninae (Anomopoda, Chydoridae), separated from genus Alona Baird, 1840

The little-known cladoceran Alona macrocopa Sars, 1894 and four related species differ from the majority of the genus Alona by unusual morphology of antenna and postabdomen. Only two species of the five, A. macrocopa Sars, 1894 and A. imitatoria Smirnov, 1989, are found to be valid. The species A. abbreviata Sars, 1895, A. duodontha Henry, 1922 and A. guernei Smirnov, 2001 are proved to be the synonims of A. macrocopa. The detailed morphology of appendages of A. macrocopa and A. imitatoria is studied for the first time. Analysis of morphology of the macrocopa-group reveals numerous characters clearly separating it from other species of Alona despite the wide diversity of this genus. Unusual morphology of the antenna, and the female and male postabdomen does not allow placement of the macrocopa-group in any other genera of Aloninae. So the new genus Armatalona gen. n. is suggested. This new genus is the highly specialized marginal genus of Aloninae, closely related only to the Australian endemic genus Pseudomonospilus Smirnov, 2001. The morphology of Armatalona gen. n. and its place within Aloninae are discussed.     

A new genus and species of oribatid mites <Emphasis Type="Italic">Scarabacarus longisensillus</Emphasis> gen. et sp. n. (Acariformes,Liacaridae) from the Caucasus

A new genus and species, Scarabacarus longisensillus gen. et sp. n., of the family Liacaridae are described from the Caucasus (Azerbaijan and Abkhazia): The new genus Scarabacarus is characterized by the highly convex body, straight anterior margin of the notogaster, narrow fusiform sensilla, the lamellae situated on the lateral margins of the prodorsum, the absence of interlamellar and notogastral setae (besides one posterior pair), presence of four pairs of genital setae, and tridactylous leg tarsi.     

Leydigia louisi louisi Jenkin, 1934 in the Neotropics, L. louisi mexicana n.subsp. in the Central Mexican highlands

Leydigia louisi Jenkin, 1934 was recently redescribed by Kotov (2003). We found in Guatemala and South of Mexico populations of this species, similar with the typical African form. A re-examination of Daday's (1902) specimens from Patagonia demonstrated that his material, determined as L. leydigi, was also L. louisi. At the same time, we describe a new subspecies Leydigia louisi mexicana n.subsp. from four water bodies on the central Mexican plateau (State of Mexico). Parthenogenetic females, ephippial females, juvenile and adult males are described. SEM illustrations are given for L. louisi mexicana n.sp. It differs from the nominotypical subspecies by (1) ocellus of irregular shape; (2) chitinous insertions within distal segments of swimming setae far from bases of segments; (3) on IDL, 3 bunches of very long setules; (4) setules on distal lobe of limb II long; (5) longest seta of exopodite III with long, fine setules; (6) seta 1 of exopodite IV relatively short; (7) a two-lobed body on inner margin of limb V. Features 2–6 were never used in the genus previously, but were applied in the systematics of other genera of Chydoridae. The ranges of these two subspecies are, probably, the Neotropical and Holarctic regions.     

<Emphasis Type="Italic">Foxtosognus rarus</Emphasis> gen. n., sp. n.—A new genus and species of copepods (Copepoda: Calanoida) from the abyssopelagic zone of the Kuril-Kamchatka Trench

A female of Foxtosognus rarus gen. n., sp. n., a new genus and species of copepods, is described from the abyss of the Kuril-Kamchatka Trench. The new genus is placed in the family Arctokonstantinidae, whose diagnosis is emended and supplemented with the following characters: mandibular basis with one to two setae; mandibular endopod one without setae; maxillular distal basal endite plus endopod with two to four setae or without setae. The features that distinguish Foxtosognusgen. n. from other representatives of this family are as follows: mandibular palp with a long endopod segment one, endopod segment two with seven setae, and exopod segment five with two setae; maxillula with distal basal endite lacking setae and separated from endopod bearing three setae; maxillular precoxal arthrite with seven to eight setae and exopod with four setae; maxilliped syncoxa without setae on precoxal endites and endopod of three segments. The genera Sognocalanus and Foxtonia earlier included in the Spinocalanidae are herein transferred to the Arctokonstantinidae.     

Sinharaja gen. n., a new Uropodina mite genus from Sri Lanka with description of two new species (Acari: Mesostigmata: Uropodidae)

A new Uropodina genus (Sinharaja gen. n.) is described on the basis of two new species (S. ceylonensis sp. n. and S. sinhala sp. n.) from Sri Lanka. The new genus differs by the strongly sclerotised dorsal lines, pentagonal pygidial shield, the shape and length of dorsal setae and the shape of first and fourth hypstomal setae, internal malae and epistome from the other known Uropodina genera.     

Parobia husbandi gen. n., sp. n. (Acari: Podapolipidae): subelytral parasites of paropsine beetles (Coleoptera: Chrysomelidae)

Abstract Parobia husbandi gen. n., sp. n. is described from material collected from the subelytra of the southern eucalyptus leaf beetle, Chrysophtharta agricola (Chapuis), in Tasmania, Australia. Parobia gen. n. is distinguished from other podapolipid genera adult males and females with four pairs of legs and no setae on genua I−IV and femora III−IV, adult females with setae v1 and sc2 < 20 µm, and at least two pairs of coxal setae peg-like, adult males with dorso-terminal genitalia, dorsal shields C-D-E fused, and physogastric larval females with plates C and D entire. A series of morphological plesiomorphies and biological apomorphies link Parobia gen. n. with Chrysomelobia Regenfuss, the most basal genus of Podapolipidae.     

A new genus and two new species of chigger mites (Acari: Trombiculidae) from the Laotian rock-rat Laonastes aenigmamus Jenkins, Kilpatrick, Robinson & Timmins (Rodentia: Diatomyidae)

A new chigger mite genus Laotrombicula n. g. and two new species, Laotrombicula khunboromi n. sp. (type-species) and L. fangumi n. sp., are described from the Laotian rock-rat Laonastes aenigmamus Jenkins, Kilpatrick, Robinson & Timmins (Rodentia: Diatomyidae). The new genus is most similar to Trombiculindus Radford, 1948 and Leptotrombidium Nagayo, Miyagawa, Mitamura & Imamura, 1916 and differs from these genera by having the scutum of subhexagonal or semicircular shape vs widely rectangular; pinnatifid dorsocentral idiosomal setae vs foliaceous in Trombiculindus and unexpanded in Leptotrombidium; and by the presence of serrated longitudinal crests in the middle part of scutum.     

A new genus and species of Coenosiini from Costa Rica (Diptera,Muscidae, Coenosiinae)

Palpilongus gen. n. is herein described for one species – Palpilongus bifurcus sp. n., from Costa Rica, based on male and females. The striking morphological characters of the species – palpus very long, about as long as prementum; upper calypter truncate and very short and setae of male sternite 5 bifurcated, confirm that this new species is also a new genus in the tribe Coenosiini. Male and female terminalia were dissected and illustrated.     

New water mite species of the genus <Emphasis Type="Italic">Aturus</Emphasis> (Acari,Hydrachnidia, Aturidae) from Russia

Two new species of the genus Aturus Kramer (A. tuzovskyi sp. n. and A. kimichungi sp. n.) from Russia are described. These species and closely related species of the genus Aturus are compared. A. tuzovskyi sp. n. male is characterized by a slender body, the presence of a pair of bifurcated setae on the dorsal shield, two sword ventrodistal setae equal in length on the genu of leg IV, and 10–14 pairs of acetabula. The female of this species is characterized by the oval body and the presence of 10–13 pairs of acetabula. The male of A. kimichungi sp. n. is characterized by a rounded body, the presence of a single pair of bifurcated setae on the dorsal shield; sword setae on the genu IV are longer than tibia IV; 14–21 pairs of acetabula are present. The female of this species possesses a rounded body and 18–19 pairs of acetabula.     

Report on the Polycystididae (Rhabdocoela, Kalyptorhynchia) from Australia, with the Description of Twelve New Species and Six New Genera

Twelve new species of Polycystididae Graff, 1905 are described from the Australian east coast. Nine of them could not be placed in any of the existing genera, and therefore six new genera are erected. Alchoides n. gen. differs from all other polycystidid genera by the presence of a bundle of glands that opens into the distal part of the male atrium (accessory vesicle type V). Two species are included in the genus, A. alchoides n. sp. and A. dittmannae n. sp., which differ from each other in the shape of the stylet. Ametochus gehrkei n. gen n. sp. can be distinguished from other polycystidids by the presence of a prostate vesicle type III associated with a prostate stylet type III, combined with the presence of an accessory stylet type III, while a prostate stylet type II is lacking. Typical for Arrawarria inexpectata n. gen n. sp. is the combined presence of an armed cirrus with a prostate vesicle type II connected to a prostate stylet type II. Two species are assigned to the new genus Duplexostylus n. gen.: D. rowei n. sp. and D. winsori n. sp. These two species have two unique features: a prostate vesicle type IV directly connected to a prostate stylet type III and an asymmetrical septum that surrounds the proximal part of the male atrium. They can be distinguished from each other by differences in the detailed construction of their stylets. Two new species are placed in the new genus Stradorhynchus n. gen.: S. caecus n. sp. and S. terminalis n. sp. They have unpaired gonads and a prostate vesicle type IV connected to a prostate stylet type IV, which combination of characters makes them unique within the Polycystididae. The two species differ from each other in the shape and size of the stylet. Triaustrorhynchus armatus n. gen., n. sp. is the first species of the Polycystididae to have three types of stylet in the male atrium: a prostate stylet type II, a prostate stylet type III and an accessory stylet type III. Three new species could be placed in existing genera: Cincturorhynchus monaculeus n. sp., Paraustrorhynchus caligatus n. sp. and Polycystis australis n. sp. All three differ from their congeners in the form and dimensions of their stylets. All newly described species are discussed, giving their similarities and differences with resembling species. Austrorhynchus hawaiiensis Karling, 1977 is reported for the first time in Australia, and the Australian population is compared with populations from other regions. The presence of Gyratrix hermaphroditus Ehrenberg, 1831, one new species of Paulodora Marcus, 1948 and a new genus of Typhlopolycystidinae Evdonin, 1977 is mentioned.     

A review of mites of the subfamily Picobiinae Johnston & Kethley, 1973 (Prostigmata: Syringophilidae) from North American birds

The fauna of ectoparasitic mites of the subfamily Picobiinae (Acari: Syringophilidae) associated with birds of the North America is revised. A new genus, Charadriineopicobia n. g. is proposed for two quill mite species, Ch. calidris n. sp. from Calidris alba (Pallas) (Charadriiformes: Scolopacidae) and Ch. leucophaeus (Skoracki, Hendricks & Spicer, 2010) n. comb. from Leucophaeus atricilla Linnaeus (Charadriiformes: Laridae). The new genus differs from the closely related Neopicobia Skoracki, 2011 by the presence of one pair of setae in pseudanal series and by clearly discernible chambers in each lateral branch of the peritremes, in both sexes. Additionally, a new species of Picobia Haller, 1878, P. hylocichlae n. sp., parasitising Hylocichla mustelina (Gmelin) (Passeriformes: Turdidae), is described. The species of picobiine mites presently recorded from North America are summarised.     

Revision of the Neotropical bark mantis genus Liturgusa Saussure, 1869 (Insecta,Mantodea, Liturgusini)

The praying mantis genus Liturgusa Saussure, 1869 occurs only in Central and South America and represents the most diverse genus of Neotropical Liturgusini (Ehrmann 2002). The genus includes bark dwelling species, which live entirely on the trunks and branches of trees and run extremely fast. All species included within the genus Liturgusa are comprehensively revised with a distribution stretching from central Mexico, the island of Dominica to the southeastern regions of Brazil and southern Bolivia. All known species are redescribed to meet the standards of the new treatment of the genus (11 species). Three new genera are described including Fuga gen. n., Velox gen. n., and Corticomantis gen. n. for species previously included in Liturgusa as well as Hagiomantis. Liturgusa mesopoda Westwood, 1889 is moved to within the previously described genus Hagiomantis Audinet Serville, 1838. A total of 19 species are newly described within Liturgusa, Fuga, and Velox including L. algorei sp. n., L. bororum sp. n., L. cameroni sp. n., L. cura sp. n., L. dominica sp. n., L. fossetti sp. n., L. kirtlandi sp. n., L. krattorum sp. n., L. manausensis sp. n., L. maroni sp. n., L. milleri sp. n., L. neblina sp. n., L. purus sp. n., L. stiewei sp. n., L. tessae sp. n., L. trinidadensis sp. n., L. zoae sp. n., F. grimaldii sp. n., and V. wielandi sp. n. Four species names are synonymized: Liturgusa peruviana Giglio-Tos, 1914, syn. n. = Liturgusa nubeculosa Gerstaecker, 1889 and Hagiomantis parva Piza, 1966, syn. n., Liturgusa sinvalnetoi Piza, 1982, syn. n., and Liturgusa parva Giglio-Tos, 1914, syn. n. = Mantis annulipes Audinet Serville, 1838. Lectotypes are designated for the following two species: Liturgusa maya Saussure & Zehntner, 1894 and Fuga annulipes (Audinet Serville, 1838). A male neotype is designated for Liturgusa guyanensis La Greca, 1939. Males for eight species are described for the first time including Liturgusa cayennensis Saussure, 1869, Liturgusa lichenalis Gerstaecker, 1889, Liturgusa guyanensis La Greca, 1939, Liturgusa maya Saussure & Zehntner, 1894, Liturgusa nubeculosa Gerstaecker, 1889, Fuga annulipes (Audinet Serville, 1838), Corticomantis atricoxata (Beier, 1931), and Hagiomantis mesopoda (Westwood, 1889). The female of Fuga fluminensis (Piza, 1965) is described for the first time. Complete bibliographic histories are provided for previously described species. The spelling confusion surrounding Liturgusa/Liturgousa is resolved. Full habitus images for males and females are provided for nearly all species. Habitus and label images of type specimens are provided when possible. Diagnostic illustrations of the head and pronotum for males and females are provided for all species when possible. Illustrations of male genital structures are provided for all species for which males are known. Measurement data, including ranges and averages, are provided for males and females of all species. Combined male and female genus and species level dichotomous keys are provided with a Spanish translation. A complete table of all examined specimens lists label data, museum codes, repositories, and other specimen specific information. A KML file with all georeferenced locality records is downloadable from mantodearesearch.com for viewing in Google Earth. Natural history information is provided for species observed by the author.     

Description of a New Genus and Three New Species of Figitinae (Hymenoptera: Cynipoidea: Figitidae) from Colombia

A new genus and three new species of Figitinae (Hymenoptera: Figitidae) are described from Colombia: Ferpereira Pujade-Villar n. gen., Ferpereira fiorellae Pujade-Villar n. sp., Neralsia levis Pujade-Villar & Petersen-Silva n. sp., and Figites colombiensis Pujade-Villar & Paretas-Martínez n. sp., which is the first species of Figites Latreille from Colombia and the second from South America. The diagnostic characters of these new taxa are illustrated.     

Gall midges of the supertribe Stomatosematidi (Diptera,Cecidomyiidae) in the Palaearctic Region,with descriptions of new taxa from the Late Eocene Rovno amber: 1. <Emphasis Type="Italic">Stomatosema,Vanchidiplosis, Clarumreddera</Emphasis> gen. n.

Three recent genera are included in the supertribe Stomatosematidi: Stomatosema (16 species), Vanchidiplosis (4 species), and Didactylomyia (3 species). Seven species of the genus Stomatosema and two species of the genus Vanchidiplosis occur in the Palaearctic Region. No reliable findings of representatives of the supertribe were known in fossilized condition. One new genus and 3 new species are described from amber of the Late Eocene age (Rovno Region): Stomatosema iljieteugeniae sp. n., Clarumreddera korneyevi gen. n. et sp. n., and C. conceptiva sp. n.     

Descriptions of two new species of feather mites (Acarina: Psoroptidia: Pteronyssidae) from Ivory Coast

Two new feather mite species of the family Pteronyssidae Oudemans, 1941 collected from birds captured in Ivory Coast are described: Pteronyssoides cyanomitrae n. sp. from Cyanomitra obscura (Jardine) (Passeriformes: Nectariniidae) and Conomerus pygmaeus n. sp. from Hylia prasina (Cassin) (Passeriformes: Macrosphenidae). Pteronyssoides cyanomitrae n. sp. belongs to the nectariniae species group and differs from the closest species, P. garioui Gaud & Mouchet, 1959, in having, in males, the adanal shield present and setae f longer than setae d on the tarsus III; females of this species have the hysteronotal shield with two small median incisions on the anterior margin barely extending beyond the level of setae e2. Conomerus pygmaeus n. sp. is the first species of this genus found on a passerine host, and seems to be more similar to C. sclerosternus Gaud, 1990. This new species has the following distinctive characters: in females, the opisthosoma has small lobe-like extensions and the central sclerite is fused posteriorly with the lateral opisthosomal sclerites; in males, coxal fields I–IV lack large sclerotised areas.     

Gall midges of the supertribe stomatosematidi (Diptera, Cecidomyiidae) in the Palaearctic region, with description of new taxa from the Late Eocene Rovno amber: 3. Groveromyia gen. n. analysis of biometric parameters of the recent and late eocene genera and species

The new genus Groveromyia gen. n. was described from the Late Eocene Rovno amber. The genus includes 4 species: G. occlusa sp. n., G. digna sp. n., G. astrosa sp. n., and G. concinna (Fedotova, 2005) comb. n. (Bryocrypta). Some changes in the biometric parameters of the genera and species were revealed relative to those in the recent and the Late Eocene Stomatosematidi. Keys to the recent and fossil genera of the tribe Stomatosematidi and the species of the genus Groveromyia are given.     

Gall midges of the supertribe stomatosematidi (Diptera,Cecidomyiidae) in the Palaearctic region,with descriptions of new taxa from the late Eocene Rovno Amber. 2. The genera <Emphasis Type="Italic">Didactylomyia</Emphasis> and <Emphasis Type="Italic">Rovnodidactylomyia</Emphasis> gen. n.

One new genus (Rovnodidactylomyia Fedotova et Perkovsky, gen. n.) and four new species (Didactylomyia dlusskyi sp. n., Rovnodidactylomyia zosimovichi gen. n. et sp. n., R. sidorenkoi sp. n., and R. iconica sp. n.) are described from an amber sample of the late Eocene Period (Rovno District, Ukraine). Two species from a Baltic amber sample of the late Eocene Period, described earlier in the genus Bryocrypta, are attributed to the genus Rovnodidactylomyia (R. girafa (Meunier, 1904) comb. n. and R. capitosa (Meunier, 1904)). The first fossil species of the genus Didactylomyia is described for the first time; two contemporary Palaearctic species are recorded. Keys to the species of the genus Didactylomyia are given.
