A revision of the Asian and European species in the subgenus Amiota Loew (Diptera,Drosophilidae) and the establishment of species-groups based on phylogenetic analysis

A total of 53 Amiota (s. str.) species (75% of the world total) from Asia and Europe, including 10 new species, kamui, kimurai and planata from Japan, and aristata, cuii, macai, magniflava, nuerhachii, spinata and watabei from China, are reviewed with designation of two new synonymies and phylogenetic analysis. Based upon the result of cladistic analysis with 31 adult male morphological characters, the following conclusions are deduced: (1) The subgenus Amiota is monophyletic, so far as the Asian and European forms are concerned. (2) Seven monophyletic groups are recognized within this subgenus. Two of them correspond to known species-groups, the apodemata and sinuata groups, and the remaining five are established as new species-groups, the nagatai, basdeni, taurusata, alboguttata and rufescens groups. A key to all the studied species from Asia and Europe is provided.

Three new species of the brackish‐water copepod Halicyclops (Crustacea,Cyclopoida) from Ariake Bay,Japan

Three new species of the cyclopoid copepod Halicyclops are described from river estuaries of Ariake Bay, Japan. Halicyclops continentalis sp. nov. is most similar to H. laminifer, but differs by the shape of an angular protuberance on the genital double‐somite and a serrate hyaline frill of the fourth urosomite. Halicyclops sinensis described by Tai and Chen is widely distributed in China and is identifiable to H. continentalis, indicating that the population in Ariake Bay is probably a continental relict. Halicyclops uncus sp. nov., belonging to the thermophilus group, is distinguishable by the shape of the lateral process on the genital double‐somite, a frill of the fourth urosomite and caudal rami; it is probably endemic to Japan. Halicyclops ariakensis sp. nov. differs from the other congeners by a combination of the shape of the prosome, urosomal hyaline frills and caudal ramus length; it is considered endemic to Ariake Bay.     

Two new species of the genus Sinella Brook, 1882 (Collembola: Entomobryidae) from East China

Two new species, Sinella hexaseta sp. nov. and Sinella pauciseta sp. nov., collected from East China, Anhui and Zhejiang provinces, respectively, were described. Both are easily discriminated from each other and all known Sinella species by their unique dorsocentral chaetotaxic patterns on Abd. IV. In S. pauciseta sp. nov., postlabial setae H_1–4 are ciliate, which are smooth in all other known species of the genus.

Stegana (Oxyphortica) convergens species group (Diptera: Drosophilidae) from the Oriental region,with morphological and molecular evidence

Three new species of the Stegana (Oxyphortica) convergens species group are described from South China: S. (O.) gonglui Wang and Chen, sp. nov., S. (O.) xiaoyangae Zhang and Chen, sp. nov., and S. (O.) zhulinae Wang and Chen, sp. nov. The diagnosis of S. (O.) setifrons is revised. A key to all eight species of this group is provided.

“Typhloplanoida” (Platyhelminthes: Rhabdocoela) from the Indian Ocean,with the description of six new taxa

Seven typhloplanoids from the Indian Ocean are discussed; six of them are new to science. We place four of the new species within the Trigonostomidae. Gandalfia bilunata gen. nov. sp. nov. is characterized by a tubiform stylet and two semilunar structures in the afferent duct. Mahurubia clava gen. nov. sp. nov. has a gutter‐shaped stylet and a club‐shaped mouthpiece on the bursa. Parapharyngiella involucrum gen. nov. sp. nov. is characterized by a stylet in the form of a question mark and a bursal mouthpiece with a club‐shaped and a barrel‐shaped part. Poseidoplanella halleti gen. nov. sp. nov. is characterized by an unpaired ovary, a funnel‐shaped stylet connected with a plate, and a small, tubular bursal mouthpiece. Furthermore, new data are given on Ceratopera axi. The two other new species belong to the Typhloplanidae. Aegira annabellae gen. nov. sp. nov., a marine species, is characterized by a box‐shaped stylet and a long, pseudocuticularized ejaculatory duct. Castrada trispina sp., a freshwater species, has a copulatory bursa with three spines. Mahurubia clava gen. nov. sp. nov. and Parapharyngiella involucrum gen. nov. sp. nov. occur at Zanzibar, Tanzania. The other five species have been found on Kerguelen.

New species of ptyctimous mites (Acari,Oribatida) from Cuba

Five new species of two genera of ptyctimous, soil mites (Acari, Oribatida, Steganacaridae) are described: Protophthiracarus aethes sp. nov., Protophthiracarus pinarensis sp. nov., Protophthiracarus ruseki sp. nov., Notophthiracarus granpiedraensis sp. nov. and Notophthiracarus obturatus sp. nov. The identification key for determination of Protophthiracarus species of Cuba is provided. One of the genera, Notophthiracarus, is newly found in the Antilles.

The genus Platypalpus Macquart (Diptera: Hybotidae) from Northeast Thailand with comments on the species groups in the Oriental region

The first records on the genus Platypalpus Macquart from Thailand are presented including 10 species new to science: P. fai sp. nov., P. gaemluang sp. nov., P. hualuang sp. nov., P. isaanensis sp. nov., P. nuadkhao sp. nov., P. phomyaaw sp. nov., P. seedam sp. nov., P. seeluang sp. nov., P. siamensis sp. nov., and P. thaicus sp. nov.. A key to these species is provided. All species of Platypalpus known from the Oriental Region (totally 54) are arranged into the species groups currently established for the genus. Eight species groups are recognized from the Oriental Realm and the distribution of each group is briefly discussed. The P. albiseta‐group is most diverse in the Orient with 16 species recorded. Two species of this group possess a modified structure and vestiture of certain abdominal segments that is the first record of this phenomenon in Platypalpus. Also, within the P. albiseta‐group a complex of closely related species sharing an apomorphous condition of the hypoproct has been recognized. In these species the structure of the hypoproct is likely to deal with clasping during copulation instead of the cerci and epandrial lamellae.
