The species of the genus Microtrichalus Pic, 1921 represented in the Philippines are revised. Six species are placed in the genus; in addition to M. basipennis (Pic, 1926), two species are described as new (M. retractus sp. n. and M. salvani sp. n., both from Mindanao), and three species are transferred from the genus Trichalus Waterhouse, 1877: M. bakeri (Kleine, 1929) comb. n., M. costilis (Kleine, 1926) comb. n. and M. communis (Waterhouse, 1879) comb. n. A key to the six Philippine Microtrichalus species and illustrations of their important diagnostic characters are provided. Trichalus nigricauda Bourgeois, 1886 and T. longicollis Bourgeois, 1883 are transferred to the genus Leptotrichalus Kleine, 1925. Leptotrichalus mindorosus Pic, 1925 is proposed to be a junior subjective synonym of Leptotrichalus longicollis (Bourgeois, 1883).
Monozoic cestodes of the recently amended genus Promonobothrium Mackiewicz, 1968 (Cestoda: Caryophyllidea), parasites of suckers (Cypriniformes: Catostomidae) in North America, are reviewed, with information on their host specificity, distribution and data on the scolex morphology of seven species studied for the first time using scanning electron microscopy (SEM). Evaluation of type and voucher specimens from museum collections and newly collected material of most species indicated the following valid nominal species: Promonobothrium minytremi Mackiewicz, 1968 (type species); P. ingens (Hunter, 1927); P. hunteri (Mackiewicz, 1963); P. ulmeri (Calentine et Mackiewicz, 1966); P. fossae (Williams, 1974) and P. mackiewiczi (Williams, 1974). Rogersus Williams, 1980 with its only species R. rogersi is transferred to Promonobothrium based on morphological and molecular data. Promonobothrium currani sp. n. and P. papiliovarium sp. n. are described from Ictiobus bubalus (Rafinesque) and Ictiobus niger (Rafinesque), and Erimyzon oblongus (Mitchill), respectively. The newly described species can be distinguished from the other congeners by the morphology of the scolex, the position of the anteriormost vitelline follicles and testes, the presence of postovarian vitelline follicles and the shape of the ovary. Molecular phylogenetic analyses of six species based on sequences of the small and large subunits of the nuclear ribosomal RNA genes (ssrDNA, lsrDNA) confirmed the monophyletic status of the genus and supported the validity of the species analysed. A key to identification of all species of Promonobothrium based on morphological characteristics is provided., Mikuláš Oros, Jan Brabec, Roman Kuchta, Anindo Choudhury, Tomáš Scholz., and Obsahuje bibliografii
The Japanese species of Asteiidae are revised. Six species of Asteia Meigen, 1830, are recorded here in addition to Astiosoma okinawae Sabrosky, 1957, hitherto recorded from Japan. Among them, Asteia gemina, A. longistylus, A. lunaris, and A. nigrigena are described as new to science. Asteia angustipennis Duda, 1934, and A. megalophthalma Duda, 1927, are recorded from Japan for the first time. There are conspicuous morphological differences in the male and female genitalia of the seven species of Asteia. It is suggested that Asteia angustipennis, A. concinna, and A. gemina are very closely related and may be reproductively isolated because of their body markings and male genitalia. These species are assigned to the concinna group of Asteia, newly designated in this study. A key to Japanese species and distribution maps are provided.
It is shown that under the name Mocis frugalis (F., 1775), considered to represent a widespread pest of graminaceous crops in the Eastern hemisphere and the Pacific, two species have been hitherto confused. Populations from Africa and Arabian Peninsula are described as Mocis proverai sp. n. The main characters which distinguish the African-Arabian M. proverai from M. frugalis of Asia and the Pacific are found in the genitalia, especially the configuration of the male vesica and female bursa copulatrix.
Afroaltica subaptera, a new genus and species of flea beetles (Chrysomelidae: Alticinae) from the eastern regions of southern Africa (Eastern Transvaal and Kwazulu-Natal), is described. Afroaltica gen. n. shows some similarities with the genus Dibolia Latreille, 1829 but it is easily distinguishable mainly by the simple-shaped apical spur of hind tibiae, not bifid. External habitus, scanning electronic micrographs of particular morphological features and line drawings of metafemoral spring and male and female genitalia of the new taxon are provided.
A new genus, Afromuelleria gen. n., assigned to the tribe Trachyphloeini Lacordaire, 1863, is described for four South African species of weevils: A. awelani sp. n., A. baobab sp. n., A. limpopo sp. n. and A. venda sp. n. All species are illustrated and keyed. Taxonomic status of the new genus is discussed and compared with similar genera of Trachyphloeini and Embrithini Marshall, 1942.
An annotated checklist of the tribe Mirini (Miridae: Mirinae) recorded on the Korean peninsula is presented. A total of 113 species, including newly described and newly recorded species are recognized. Three new species, Apolygus hwasoonanus Oh, Yasunaga & Lee, sp. n., A. seonheulensis Oh, Yasunaga & Lee, sp. n. and Stenotus penniseticola Oh, Yasunaga & Lee, sp. n., are described. Eight species, Apolygus adustus (Jakovlev, 1876), Charagochilus (Charagochilus) longicornis Reuter, 1885, C. (C.) pallidicollis Zheng, 1990, Pinalitopsis rhodopotnia Yasunaga, Schwartz & Chérot, 2002, Philostephanus tibialis (Lu & Zheng, 1998), Rhabdomiris striatellus (Fabricius, 1794), Yamatolygus insulanus Yasunaga, 1992 and Y. pilosus Yasunaga, 1992 are reported for the first time from the Korean peninsula. Korean specimens previously identified as Eurystylus luteus Hsaio, 1941 are correctly recognized as E. sauteri Poppius, 1915. Three new synonyms are proposed: Apolygus atriclavus Kim & Jung, 2016 syn. n. of A. xanthomelas Yasunaga & Yasunaga, 2000, A. josifovi Kim & Jung, 2016 syn. n. of A. subpulchellus (Kerzhner, 1988) and Capsus koreanus Kim & Jung, 2015 syn. n. of C. wagneri Remane, 1950. Dorsal habitus photographs of the newly described or recorded species are presented along with figures of the genitalia of the new species. Keys to Korean genera and to species of Apolygus and Stenotus are provided. Zoogeography of the East Asian Mirini fauna is also discussed., Minsuk Oh, Tomohide Yasunaga, Ram Keshari Duwal, Seunghwan Lee., and Obsahuje bibliografii
A new hair follicle mite species, Apodemodex cumulus, is described from female and male specimens collected from the muzzle, lower jaw and vertex of Mediterranean water shrews, Neomys anomalus Cabrera taken in South Bohemia, Czech Republic. A new, at present monotypie genus Apodemodex is erected for this mite species. Diagnostic for the new genus are the morphology of the gnathosoma (the characters including conspicuous continuous arched antero-lateral contours of massive ventral face) and the morphology of the leg claws, which are deeply bifurcate and without spur.
Bagrichthys majusculus, a new species of bagrid catfish from Indochina, is very similar to B. macracanthus and B. vaillantii, and has been previously identified as the former species. It differs from congeners in having a unique combination of the following characters: relatively large and broad mouth, well-developed oral dentition with homodont teeth, 10–13 gill rakers, moderately-long dorsal spine with 15–27 serrations, 9 pectoral-fin rays, inner and outer mandibular barbels with straight margins, pectoral-spine length 15.8–20.7 % SL (standard length), dorsal-spine length 24.4–32.5 % SL, length of adipose-fin base 46.0–50.7 % SL, adipose maximum height 9.9–10.5 % SL, depth of caudal peduncle 7.1–7.5 % SL, and head depth 14.0–16.1 % SL.
Blaena tamasi sp. n., the first species of Cydnidae with staphylinoid modification of wings, is described from Western Australia. The rare cases of wing modifications in Cydnidae and Pentatomoidea are briefly discussed. A key to all known species of the genus Blaena Walker is also provided.
