Doratomantispa burmanica n. gen., n. sp. (Neuroptera: Mantispidae), a new genus of mantidflies in Burmese amber

A new genus and new species of mantidflies, Doratomantispa burmanica n. gen., n. sp. (Neuroptera: Mantispidae), is described from Burmese amber. Diagnostic characters of the new genus are small body size, trichosors present around entire wing margin except basally, protarsus 5-segmented with paired, simple claws but no aroleum, profemur bearing six cuticular spines, inner surface of protibia with row of peg-like protrusions, Sc meets R₁ in region of pterostigma, costal space greatly narrows toward wing apex, with 16 veinlets in costal space on front wing while costal veinlets on hind wing are replaced by trichosors and CuP absent in hind wing. The abdomen of the mantidfly is filled with large spheres resulting from a possible rickettsial infection. Phoretic heterostigmatid mites are adjacent to the wings of the fossil.     

Notobaetis: A New Genus of Baetidae (Ephemeroptera) from South America

A new genus and species, Notobaetis penai, n. gen., n. sp., of Baetidae (Ephemeroptera), is described based upon reared specimens collected from the Cordoba Province of Argentina. This new genus appears to be phenetically intermediate between Baetis Leach and Centroptilum Eaton while possessing a unique combination of characters and one autapomorphic character.     

Bicalcasura maculata n. gen., n. sp. (Curculionoidea: Dryophthoridae) with a list of weevils described from Dominican amber

A new genus and species, Bicalcasura maculata n. gen., n. sp. (Coleoptera: Curculionoidea: Rhynchophorinae: Dryophthoridae) is described from Dominican amber as the first fossil member of the Tribe Diocalandrini. The new genus is characterised by procoxae located in the middle of the prothorax; a thick, short and strongly curved rostrum with the scape not reaching the pronotum; a weak extension of the rostrum in respect to the antennal attachment; slightly elongated fifth ventrite; narrow (not bilobed) third tarsomere and a pair of apical spurs on the protibiae. This set of characters separates the fossil from the extant genus Diocalandra Faust, 1894, the only other member of this tribe. A list of weevils (Curculionoidea) described from Dominican amber is included.

Molecular Phylogenetic Positions and Ultrastructure of Marine Gregarines (Apicomplexa) Cuspisella ishikariensis n. gen., n. sp. and Loxomorpha cf. harmothoe from Western Pacific scaleworms (Polynoidae)

Marine gregarines are unicellular parasites of invertebrates commonly found infecting the intestine and coelomic spaces of their hosts. Situated at the base of the apicomplexan tree, marine gregarines offer an opportunity to explore the earliest stages of apicomplexan evolution. Classification of marine gregarines is often based on the morphological traits of the conspicuous feeding stages (trophozoites) in combination with host affiliation and molecular phylogenetic data. Morphological characters of other life stages such as the spore are also used to inform taxonomy when such stages can be found. The reconstruction of gregarine evolutionary history is challenging, due to high levels of intraspecific variation of morphological characters combined with relatively few traits that are taxonomically unambiguous. The current study combined morphological data with a phylogenetic analysis of small subunit rDNA sequences to describe and establish a new genus and species (Cuspisella ishikariensis n. gen., n. sp.) of marine gregarine isolated from the intestine of a polynoid host (Lepidonotus helotypus) collected from Hokkaido, Japan. This new species possesses a set of unusual morphological traits including a spiked attachment apparatus and sits on a long branch on the molecular phylogeny. Furthermore, this study establishes a molecular phylogenetic position for Loxomorpha cf. harmothoe, a previously described marine gregarine, and reveals a new group of gregarines that infect polynoid hosts.     

About Bullockia gen. nov., Trichomycterus mendozensis n. sp. and revision of the family Trichomycteridae (Pisces,Siluriformes)

A new genus of the family Trichomycteridae, Bullockia, and a new species of Trichomycterus are described. Bullockia gen. nov. is a monospecific and relict genus in the freshwaters of Chile. Trichomycterus mendozensis n. sp. is a freshwater relict from Argentina. Preliminary diagnoses of the subfamilies Pygidiinae and Nematogenyinae and the genera Trichomycterus, Hatcheria and Nematogenys are given.     

Hecabolomorpha n. gen., a new Asian genus from the tribe Hecabolini (Hymenoptera: Braconidae: Doryctinae)

A new Oriental genus Hecabolomorpha n. gen. with the type species H. asiatica n. sp. is described and illustrated from India and Central China. The position of this genus in the tribe Hecabolini and its relations with hecaboline genera are discussed.     

Sturmius epiphytus n. gen. n. spec, from Colombia, a taxon of the Symphypleona (Insecta, Collembola) with an unexpected character combination

From epiphytic mosses and ferns of remnants of mountain forest in the páramo region of Colombia, Sturmius epiphytus n. gen. n. spec, a taxon that resembles the Katianniformia, is described, the appendices anales of which are, however, directed towards the posterior. Analysis of characters allows a statement of the systematic position: in phylogenetic systematics, Sturmius epiphytus and the Katianniformia form a monophylum Anteriora as the sister group of the Sminthuriformia; in Linnean categories, for Sturmius n. gen., a new family Sturmiidae must be established with a new superfamily Sturmioidea as the sister group of a new superfamily Katiannoidea.     

Thaumamermis cosgrovei n. gen., n. sp. (Mermithidae: Nematoda) parasitizing terrestrial isopods (Isopoda: Oniscoidea)

Summary A new mermithid nematode, Thaumamermis cosgrovei n. gen., n. sp. (Mermithidae: Nematoda) was found parasitizing two terrestrial isopods (Isopoda: Oniscoidea) in California. The hosts, Armadillidium vulgare (Latr.) (a pillbug) and Porcellio scaber (Latr.) (a sowbug) represent the first cases of isopods attacked by mermithid nematodes. The genus Thaumamermis can be distinguished from all previously described mermithids by the extremely dimorphic spicules, one being short and broad and the other long and filiform. It has been discovered that the nematodes are infected with an iridiovirus which commonly destroys the isopod hosts. ac]19800917     

Peltidiphonte gen. n., a New Taxon of Laophontidae (Copepoda: Harpacticoida) from Coral Substrates of the Indo-West Pacific Ocean

A new genus of the harpacticoid family Laophontidae is described and named Peltidiphonte gen. n. Eight new species are assigned to this genus; they were collected from different locations in the Indo-West Pacific Ocean, including the Comoros, the Kenyan coast, the Red Sea, the Andaman Islands, the northern coast of Papua New Guinea, the Solomon Islands and the northeastern coast of Australia. Most of the specimens were collected from dead coral substrates, suggesting a close affinity between the members of the new genus and this substrate. Peltidiphonte gen. n. can easily be discriminated from other genera of the family by the extremely depressed body and by the shape of the antennule, bearing two (or three) processes on the first segment and a hook-like process along the outer margin of the second segment. An identification key for the new genus is provided.     

Sumatrella chelonica gen. n., sp. n., a new remarkable genus and species from Indonesia,Sumatra (Acari,Uropodina, Oplitidae)

A new genus Sumatrella gen. n. is described and illustrated based on the new species Sumatrella chelonica sp. n. collected in Sumatra, Indonesia. The new genus belongs to the family Oplitidae based on its hypertrichous internal malae and the absence of strongly sclerotized structures on the dorsal shield. The new genus is closely related to the genus Chelonuropoda Sellnick, 1954 but the transverse furrow on ventral idiosoma close to coxae IV and the strongly sclerotized C-shaped dorsal line are missing in the new genus. These characters can be found in species of Chelonuropoda.     

Grellia gen. n. for Eucoccidium of Grell (1953) Preoccupied*

Grellia gen. n. is established for the genus Eucoccidium of Grell (1953) preoccupied, and the classification of the apicomplexan order Protococcidiorida Kheisin, 1956 is reviewed, giving diagnoses, type species and a list of species. Grelliidae fam. n. is established for the genera Grellia, Coelotropha, Myriosporides and Defretinella.     

Thermopsis thermophila n. gen. n. sp. from hot springs in Nevada, U.S.A. (Crustacea, Ostracoda)

Thermopsis thermophila n. gen. n. sp., a new freshwater ostracod species is described from hot springs in Nevada, U.S.A. The animals were collected within a temperature range of 40–55°C. The new genus belongs to the Ostracoda Podocopida Cypridoidea Cyprididae Cypridopsinae.     

Lyneborgimyia magnifica gen. et sp.n. (Diptera: Syrphidae) from Tanzania,with a phylogenetic analysis of the Eumerini using new morphological characters

Lyneborgimyia magnifica gen. et sp.n. is described and placed with Merodon Meigen and Platynochaetus Wiedemann in the Merodon genus group within the tribe Eumerini. New morphological characters and terms are introduced, and precise definitions proposed for characters applied inconsistently in the literature. The species possesses several unique autapomorphies, including an additional cross‐vein between R₄₊₅ and M₁, and a sclerotized connection between sternite 1 and the metepimeron, which are unknown otherwise within Diptera. A parsimony‐based phylogenetic analysis including 73 characters from the adult morphology provides strong support for the monophyly of the Eumerini (Eumerus Meigen, Azpeytia Walker, Lyneborgimyia, Merodon, Platynochaetus) and the Merodon genus group, whereas no support is found for the possible monophyly of the genus Eumerus. A sister‐group relationship is indicated between the Afrotropical Lyneborgimyia and the Palaearctic Platynochaetus.     

Hugotdiplogaster neozelandia n. gen., n. sp. (Nematoda: Diplogasteridae), a parasite of the New Zealand endemic slug,Athoracophorus bitentaculatus (Quoy & Gaimard, 1832) (Gastropoda: Athoracophoridae)

Abstract

A new genus and a new species are described for nematodes removed from the genital tract of Athoracophorus bitentaculatus in New Zealand. Hugotdiplogaster neozelandia n. gen., n. sp. is different from other genera in the Diplogasteridae by the shape of the stoma and by possessing a very robust and large gubernaculum. It is the first time that a diplogasterid has been reported associated with a mollusc. The localisation of the nematode in the genital tract of slugs raises questions about its life cycle and effect on the host.     

A new genus and a new species of tachinids (Diptera,Tachinidae) from the south of middle Asia

Ventoplagia gen. n. is described, with the type species Ventoplagia brevirostris sp. n. The frontal bristles extending only to the base of the pedicel, 2+3 dorsocentral bristles, 0+2 intraalar bristles, the absence of prealar bristle, the short and fine anepimeral (pteropleural) bristle, the scutellum without lateral bristles, and the welldeveloped posteroventral bristle of the hind tibia indicate that the new genus belongs to tribe Minthoini. Ventoplagia gen. n. is closely related to the genus Palmonia Kugler. The characters distinguishing these genera are given.     

Cochliopodium arabianum n. sp. (Amorphea,Amoebozoa)

A new species of Cochliopodium isolated from freshwater at Arabia Lake in Lithonia, GA, USA is described based on light microscopic morphology, fine structure, and molecular genetic evidence. Cochliopodium arabianum n. sp., previously labeled as “isolate Con1” in prior publications, has been shown to group within the genus Cochliopodium in our molecular phylogenetic analysis. Light microscopy and fine structure evidence indicates the new isolate not only shares characters of the genus but also unique distinctive features. Cochliopodium arabianum n. sp. is typically round when stationary; or oval to sometimes broadly flabellate or triangular in shape during locomotion, with average length of 35 μm and breadth of 51 μm. Fine structure evidence indicates C. arabianum n. sp. has tower‐like scales, lacking a terminal spine, sharing high similarity with its closest relative C. actinophorum. However, the scales of C. arabianum n. sp. are unique in height and the breadth of the base plate. Both morphological and molecular data, including SSU‐rDNA and COI, indicate that this new species falls in a clade sufficiently different from other species to suggest that it is a valid new species.     

Achilaophonte maxima gen.n., spec.n., a new taxon of the Laophontidae (Copepoda,harpacticoida) from the high Antartic (Weddell Sea)

Male and female of a new genus and species of the family Laophontidae, Archilaophonte maxima, are described. The specimen was found in the high Antartic (Weddell Sea) and apprears to be the most primitive genus up to now within the superfamily Laophontoidea as defined by Huys (1990). Based on its setation of legs and mouth parts, however, it can be placed unequivocally into the family Laophontidae. Archilaophonte maxima gen. n. shows close affinities to the laophontid genus Esola Edwards 1891. Both genera form a monophyletic group which is interpreted here as the first and most primitive offshot in the evolution of the Laophontidae. The synapomorphies of the former lineage are the shape of the protopodite of the P1 and shape and setation of the female P5.
