The recent delimitation of the cambalopsid genera Hypocambala and Glyphiulus is debatable. The focus of controversy is whether the presence of crests on the trunk rings is an appropriate key character dividing these two genera. To address this issue, we conducted a molecular phylogenetic analysis including species with or without crests belonging to Hypocambala and species with crests belonging to Glyphiulus. The results of the phylogenetic analysis suggest that cambalopsids with crests are monophyletic and sister to a species without crests. Hypocambala polytricha, a cambalopsid with crests that is in a clade with crested Glyphiulus species, should be transferred to Glyphiulus. Therefore, a new combination is proposed, Glyphiulus polytrichus comb. nov. In addition, a discussion on the boundary between these two genera and a description of a new species, Hypocambala zizhongi sp. nov., are provided.Taxonomic and biological notes are given for the East Asian sawfly Pristiphora ribisi Togashi, 1990, injurious to Ribes. The following new synonyms of this species are proposed Pristiphora (Pristiphora) anivskiensis Haris, 2006, syn. nov., Pristiphora (Pristiphora) nigrocoreana Haris Zsolnai, 2007, syn. nov. and Pristiphora grossulariae Anon., 1912 [a primary homonym of Pristiphora grossulariae Walsh, 1866], syn. nov. The lectotype of Pristiphora grossulariae Anon., 1912 is designated. Redescriptions of the adult and immature stages are given. The male is described for the first time. The life history and host plants are summarized. Its close relative, Pristiphora appendiculata (Hartig, 1837), is excluded from the fauna of Japan.Fourteen species/subspecies of the subgenus Tipula (Vestiplex) Bezzi (1924) were previously known to occur in the Northwest China. Here, four species are added to the fauna of this region. Among them T. (V.) quadricorna sp. nov. and T. (V.) shaanxiana sp. nov. are described and illustrated as new; T. (V.) coquillettiana Alexander, 1924 and T. (V.) scripta Meigen, 1830 are reported from China for the first time. Furthermore, we re-described and illustrated the T. (V.) kuwayamai Alexander, 1921 based on additional morphological characters. A key to the species of Tipula (Vestiplex) from Northwest China is presented.Three new species, Macropsis dalhousiensis sp. nov. (India Himachal Pradesh), M. krishna sp. nov. (India Karnataka) and M. puttarudriahi sp. nov. (India Arunachal Pradesh) are described and illustrated. M. krishna breeds on Acacia catechu and is actively attended by the ant Camponotus sp. in nymphal and adult stages. A checklist and a revised illustrated key to species of the genus for the Indian subcontinent are also given.Specimens of the Opiinae subfamily (Hymenoptera Braconidae) were collected using Malaise traps during 2010-2011 in Northern Iran (Alborz, Guilan, Mazandaran, Qazvin and Tehran provinces). A total of 32 species belonging to 12 genera were identified, of which 11 species are new records for the fauna of Iran Apodesmia posticatae (Fischer, 1957), Apodesmia striatula (Fischer, 1957), Biosteres (Chilotrichia) advectus Papp, 1979, Bitomus (Bitomus) multipilis Fischer, 1990, Desmiostoma parvulum (Wesmael, 1835), Opius (Misophthora) rufimixtus Fischer, 1958, Opius (Opiothorax) phytobiae Fischer, 1959, Opius (Misophthora) mischa Fischer, 1968, Opius (Opiothorax) attributus Fischer, 1962, Phaedrotoma pseudonitida (Fahringer, 1943) and Utetes curtipectus (Fischer, 1958). In addition, 21 species are new provincial records. Local and global distributions of all 32 species as well as diagnostic characters of each of the newly recorded species are provided.Stomopogon Malloch (Diptera, Muscidae) is a Neotropical genus recorded from Argentina, Bolivia, Brazil, Chile and Peru. In this contribution, the genus is revised, and three new species are described, one from Bolivia (Murillo, La Paz), one from Brazil (Palmas, Paraná) and one from Peru (Wayqecha, Cuzco). The descriptions include color images, illustrations and ultrastructural morphology of the terminalia of the adult. We provide an identification key to the species of Stomopogon and an updated map with species’ distributions. Stomopogon acuta (Malloch, 1934) is proposed as a new junior synonym of S. inculta Stein, 1911.Four species of the genus Lepidozonates Park, 2013 are reviewed in China. Lepidozonates semiovatus sp. nov. is described as new; L. prominens Park, 2013 and L. tenebrosellus Park, 2013 are newly recorded in China; Philharmonia adusta Park, 2000 is transferred to the genus Lepidozonates as L. adusta comb. nov.; and L. U18666A viciniolus Park, 2013 syn. nov. is proposed as a new synonym of P. adusta. The female of L. tenebrosellus is described for the first time. Images of adults and genitalia of the Chinese species are provided, along with a key to all the five species of Lepidozonates.Two new species of the genus Anomala Samouelle, 1819 are described A. dianopicta Zhao, new species from Yunnan and A. huangyuzhoui Zhao, new species from Hunan. New distributional records for Anomala bella Arrow, 1917, A. blaisei Ohaus, 1914, A. cyanipennis Lin, 1999 and A. granuliformis Lin, 1996 are presented.The potamanthid mayfly genus Rhoenanthus Eaton, which was not investigated systematically before in China, is revised herein. Six species in the subgenus Potamanthindus are recognized. Among them, R. sapa, R. obscurus and R. coreanus are new records for this country, and the presence in China of the species R. magnificus and R. hunanensis is confirmed, the nymphal stage of the latter species being described for the first time. Phylogenetically and evolutionarily, R. sapa, which has shorter maxillary and labial palpi, foretibiae and less setaceous mouthparts and forelegs, is close to the plesiomorphic genus Potamanthus. At the same time, R. youi, R. obscurus and R. coreanus, which have larger tusks and spines, longer and more setaceous foretibiae, maxillary and labial palpi, are somewhat similar to the other subgenus Rhoenanthus (Rhoenanthus). The Chinese Rhoenanthus (Potamanthindus) species indicate that the genus Rhoenanthus is closer to Anthopotamus rather than Potamanthus, both of them bearing elongated mandibular tusks.
