A new genus and species of Heteromysini (Crustacea‐Mysidacea) from the backwater of Kochi (Kerala,India)

Kochimysis pillaii, a new genus and species of Heteromysini collected from the backwater of Kochi, is described. The new genus is closely related to the genus Deltamysis but is distinguishable from the latter by the following characters: antennules of male have a small setiferous lobe; antennal scale is without distal suture; second segment of mandibular palp broad; endopodite segments of maxilla subequal in length; in male carpus and propodus of second thoracic endopod with notches on outer margin; outer pair of apical spines on telson longer than the inner pair.     

Five new Polycladida (Platyhelminthes: Acotylea) species from the Aegean Sea with remarks on the prostatic structures

Five species of polyclads, Imogine melihertani sp. nov., Pseudoplanocera izmirensis gen. et sp. nov., Izmira cinari gen. et sp. nov., Izmira turkeyi sp. nov. and Pseudodiscocelis aegeanensis gen. et. sp. nov., were collected in Izmir Bay, Turkey, Aegean Sea. I. melihertani is characterized by an anchor-shaped seminal vesicle, penis papilla, and ciliated male and female atria. P. izmirensis possesses spermiducal bulbs, a free prostatic vesicle, cirrus bulb, armed cirrus and Lang's vesicle. The genus Izmira is established based on the presence of a penis rod, true seminal vesicle, an interpolated prostatic vesicle of atomata-type and vagina bulbosa. Izmira cinari has an elongated body; a pointed penis and the oviducts enter the vagina bulbosa separately. Izmira turkeyi is characterized by an oval body, rod-shaped penis and the oviducts join before entering the vagina. Pseudodiscocelis is characterized by prostatoid organs, a lobed penis and ciliated and glandular cells in the male antrum.     

Shamshevia,a new genus of long-legged flies from Namibia (Diptera: Dolichopodidae: Diaphorinae)

The genus Shamshevia Grichanov, gen. nov. is described from Namibia to accommodate a new species, Shamshevia hoanibensis Grichanov sp. nov. Despite flattened posterior mesonotum, the new genus is placed in the subfamily Diaphorinae and is considered close to the genus Dactylonotus Parent, differing from the latter in peculiar characters of male antenna, wing and genitalia.     

Two new South American species of Acrobelus Stål (Hemiptera: Cicadellidae: Cicadellinae) with a key to the species of the genus

Two new leafhopper species of the Neotropical genus Acrobelus Stål, 1869 are described and illustrated: A. nessimiani sp. nov. from Peru (Amazonas Department) and A. rakitovi sp. nov. from Ecuador (Orellana Province). The two new species, distinguished from the other Acrobelus species by their remarkably long male subgenital plates and by the fusiform macrosetae present on these plates, seem to be closely related. A key to male specimens of the five known species of Acrobelus is provided. Taxonomic notes on the genus are included.     

Re-evaluation of the fossil Phoridae (Diptera)

I re-evaluated the known fossil phorids after re-examining much of the Baltic amber and Dominican amber fauna. Many extant genera reported from Eocene Chinese and Eocene/Oligocene Baltic amber are actually not present; instead there are representatives of relatively primitive stem-group taxa. A new genus and species of fossil phorid, Limulomyia tyche, based on a male and a limuloid female, is described from Baltic amber. Some changes in the taxonomy of amber phorids are proposed: Pseudometopina Disney is synonymized with Metopina Schmitz (new synonymy), Diplonevra meunieri Brues is transferred to the genus Godavaria Brown (new combination), Protophorites fimbriatus Brues is considered a junior subjective synonym of Protoplatyphora tertiaria Brues (new synonymy) and Phalacrotophora tertiara Statz is transferred to the genus Gymnophora (new combination). The oldest confirmed dates for extant phorid genera are given.     

A taxonomic revision of the genus Stempellinella (Diptera: Chironomidae)

The species of the chironomid genus Stempellinella are revised, described, and figured, and keys to known larvae, pupae, and male and female adults are presented. Five species new to science are diagnosed and described. An emended generic diagnosis of Stempellinella is given and morphological differences from its putative sister genus Zavrelia are discussed. The partial cytochrome oxidase subunit I (COI) gene sequences (DNA barcodes) of 10 Stempellinella species are presented and the variation in genetic distances within and between species is compared. The results indicate that DNA barcodes are suitable molecular markers for identification of Stempellinella species. The following life stages and species are diagnosed and described: the larva, pupa, male, and female of S. brevis, S. chambiensis, S. ciliaris, S. edwardsi, S. fimbriata sp. n., S. flavidula, S. leptocelloides, S. saltuum, and S. truncata; the pupa, male, and female of S. reissi and S. tamaseptima; the larva, pupa, and male of Stempellinella boltoni sp. n.; the pupa and male of S. lamellata sp. n.; the male and female of S. coronata; and the male of S. apicula, S. brevilamellae, S. distincta sp. n., and S. sublettorum sp. n. Two pupal types are described but not formally named. The following changes of combination are made: Stempellina chambiensis and Stempellina truncata are transferred to the genus Stempellinella. Zavrelia inopinata is listed as a new junior synonym of Stempellinella ciliaris.     

First record of the genus Atlantistylis Reyss, 1975 (Crustacea: Cumacea) from the North Atlantic,with the description of a new species

A new species of the genus Atlantistylis Reyss, (Diastylidae) is described from the Atlantic Frontier Margin (North‐East Atlantic). This is the first record of the genus Atlantistylis from the North Atlantic. The new species Atlantistylis borealis can be recognized by the presence of spines on the frontal and lateral lobes of the carapace combined with their absence on the pereon and pleon; the first pereopods are very long. The small telson with two small apical acuminate setae and the absence of pleopods in the male are characteristic of the genus.     

Water mites of the family Hygrobatidae Koch from southern Africa (Acari: Hydrachnidia)

New records are given of the water mite family Hygrobatidae (without the genus Atractides) from southern Africa (South Africa, Botswana, Namibia). In addition to one new subgenus of the genus Hygrobates, namely Inflatibates, four new species are described, namely Hygrobates draconicus, H. laceratoides, H. okavangoensis, and H. inflatipes as well as one new subspecies, namely Hygrobates spathuliferus cederberg. The following synonyms are established: the subgenus Capobates Thor with Hygrobates Koch, Hygrobates sanguineus transvaalensis K. O. Viets with Hygrobates spathuliferus (Lundblad), and Ambiguobates permixtus agnewi K. O. Viets with Ambiguobates permixtus K. Viets. The male of Australiobates pilosus (K. Viets) is described for the first time. The synonymization of Diversibates with Australiobates can now be confirmed. Finally, keys are given for the known genera of southern Africa, as well as for all known species of the genus Hygrobates from southern Africa.     

A synopsis of the subterranean mealybug genus Neochavesia Williams and Granara de Willink (Hemiptera: Pseudococcidae: Rhizoecinae)

The neotropical mealybug genus Neochavesia, associated with the ant genus Acropyga Roger, is discussed and placed in the tribe Xenococcini on the bases that it lacks dorsal ostioles, the distal end of the circulus is depressed and cup-shaped, and the third-instar female is a pupa. These are characters shared by Xenococcus Silvestri and Eumyrmococcus Silvestri, also in the tribe Xenococcini, and differ from those in the tribe Rhizoecini, the other tribe in the subfamily Rhizoecinae. Two new species, Neochavesia iwokramae sp. nov. and N. lapollai sp. nov., are described from Guyana, and the female pupal instar and adult male of N. lapollai and the adult male of N. caldasiae (Balachowsky) are described and illustrated. A key to adult females is provided.     

The sentinel crabs of the genus Chaenostoma (Stimpson, 1858) (Crustacea: Brachyura: Macrophthalmidae), with description of a new species and new records

The genus Chaenostoma (Stimpson, 1858) so far includes four distinct species, i.e. C. boscii (Audouin, 1826), C. lisae (Poupin and Bouchard, 2010), C. punctulatus Miers, 1884, and C. sinuspersici (Naderloo and Türkay, 2011). Chaenostoma java n. sp. is here described as a fifth species from Java (Indonesia) easily distinguished from its congeners by the features of the male first pleopod, the penultimate segment of the male abdomen, and the unique female gonopore. The new species is most similar to C. lisae, but they differ in the morphology of the male chelipeds and female gonopores. Chaenostoma lisae is redescribed and recorded from Madagascar, Mayotte I. and New Caledonia. An identification key for the genus is provided.     

First record of the genus Agnara (Isopoda: Oniscidea) from Iran with descriptions of two new species

Terrestrial isopods of the genus Agnara Budde-Lund, 1908 have been recorded from Iran for the first time. Two new species, Agnara tarahomii n. sp. and Agnara haselii n. sp., are described and their diagnostic characters are figured. Agnara tarahomii is characterized by the shape of the male pleopod exopodite I with sinuous distal margin. Agnara haselii is distinguished by a setose area on the ventral margin of the male pereopod VII ischium and the sinuous distal margin of pleopod exopodite I.     

A new genus of freshwater crab (Crustacea: Decapoda: Brachyura: Potamidae) from Thailand,with a description of a new species

A new genus, Stelomon, is established for the Thai freshwater crabs Potamon kanchanaburiense Naiyanetr, 1992, and P. pruinosum Alcock, 1909. The unique structure of the male first pleopod is the key diagnostic generic character. One new species, which differs in the form of the male first pleopod, is also described. A key to the species of Stelomon is included.     

New species of Hygiella Mesnil (Diptera: Tachinidae), parasitoids of leaf insects (Phasmatodea: Phylliidae)

The Oriental genus Hygiella Mesnil is revised: three species are described as new, Hygiella angustifrons sp. nov., Hygiella luteipes sp. nov. and Hygiella proclinata sp. nov., and two known species are re-described, Hygiella nigripes Mesnil and Hygiella pygidialis Mesnil. A key to these five species is provided. The host of H. proclinata, Phyllium siccifolium (Linnaeus) (Phasmatodea: Phylliidae), is recorded for the first time as a host of the Tachinidae. The systematic position of Hygiella is discussed and the genus is placed in the tribe Acemyini (Exoristinae) based on the structure of the male terminalia.     

Reflections on the genus Amaga Ogren and Kawakatsu 1990, and description of a new genus of land planarian (Platyhelminthes: Tricladida: Geoplanidae)

Amaga amagensis, the type species of the genus Amaga, and Amaga bogotensis are re-described. Detailed analysis of the morphology of A. amagensis revealed important taxonomic features, such as testes located dorsally to the supraintestinal parenchymal muscular layer, and secretory accumulations opening through the lateral margins of the body. These characters, as well as other morphological features, are discussed, culminating in an emendation of the generic diagnosis of Amaga. Amaga bogotensis exhibits a characteristic set of morphological features, namely an eversible penis, a male atrium lined with large musculosecretory papillae, and independent muscular coats around both male and female atrium. Therefore, a new genus is proposed for this species.     

A revision and phylogenetic re-evaluation of the family Schizopodidae (Coleoptera,Buprestoidea)

The Schizopodidae (formerly subfamily Schizopodinae, family Buprestidae) is elevated to family status, based on a review of its morphology including wing venation, male and female genitalia, larvae, and also a cladistic analysis of in-group and out-group comparisions. Two tribes are recognized: Schizopodini LeConte with one genus, Schizopus LeConte and Dystaxiini Théry with two genera: Dystaxia LeConte and Glyptoscelimorpha Horn. The genus Schizopus contains two species: S. laetus LeConte and S. sallei Horn with one new subspecies, S. sallei nigricans Nelson. The genus Dystaxia includes two species: D. murrayi LeConte, and D. elegans Fall. The genus Glyptoscelimorpha is separated into two subgenera: G. (s. str.) with two species, G. marmorata Horn, and G. viridis Chamberlin; and G. (Dystaxiella) Knull, new status, with one species, G. (D.) juniperae (Knull), new combination, with a new subspecies, G. (D.) juniperae viridiceps Nelson. All taxa are described and information on variation, type localities, distribution, biology, and comparisons are given for each species. Keys to taxa for tribes to subspecies are provided. Illustrations for all species, including habitus, male and female genitalia and other parts, as well as cladograms of relationships are presented. Lectotypes are designated for the following: Yermoella helferi Obenberger, Dystaxia elegans Fall and Glyptoscelimorpha marmorata Horn. Tables of taxa, characters and character states used in the cladistic analysis are included.     

Review of the family Rotoitidae (Hymenoptera: Chalcidoidea), with description of a new genus and species from Chile

A new genus and species of Rotoitidae, Chiloe micropteron Gibson and Huber, is described from females and one male from Chile. The taxon is the second known genus and species, and the male is the only one known for the family. Scanning electron micrographs illustrate external and internal structure of C. micropteron females, and external structure of Rotoita basalis     

A new genus and six new species of the Parabathynellidae (Bathynellacea,Syncarida) from the Kimberley region,Western Australia

Six new species of a new genus of the Parabathynellidae are described from the Kimberley Region, Western Australia. The erection of the new genus, Kimberleybathynella gen. nov., is based on the two‐segmented antenna, the partial fusion of the second and third segments of the maxilla, and the setal condition of the uropodal exopodite, where the outer seta is longer than the inner one. The one‐segmented exopodite of thoracopods I–VII and hemispherical form of male thoracopod VIII suggest the close relationship of Kimberleybathynella to the genus Atopobathynella.     

On Rembus (Colpodes) brunneus MacLeay (Coleoptera: Carabidae,Platynini): redescription and relationships

The use of the generic name Colpodes MacLeay, 1825, is reviewed, along with characteristics previously attributed to the genus by various authors of Carabidae. The single known specimen of the type species, Rembus (Colpodes) brunneus MacLeay, is designated as lectotype, redescribed and figured. Based on comprehensive character analysis, including external anatomical, male genitalic, and female genitalic and reproductive tract characters, application of the generic-level name Colpodes is restricted to a clade of Javanese species also including Colpodes brittoni Louwerens and C. latus Louwerens. In order to further nomenclatural stability within Platynini, Colpodes should best be considered a subgeneric component of an expanded genus Platynus Bonelli, 1810.
