First Time

The genus Microcostatus was described for the first time by Johansen & Sray in 1998. They established a new genus in the family Naviculaceae for Navicula krasskei. Subsequently, Lange-Bertalot proposed the transfer of further species from the genus Navicula to the Microcostatus. Species determination is very difficult using light microscopy since species are small and very similar to each other, and only ultrastructural features allow their placement in the genus. The aim of this paper was to describe morphologically and ecologically two new species of the genus Microcostatus from aerial habitats in Germany and Poland and compare their morphologies with the original gathering of Navicula egregia. Polish material was collected once a month from April to November 2013 at two sampling sites located in cultivated fields. For comparison, German original material from the Hustedt Collection was also observed. During this study, Microcostatus aerophilus sp. nov. and M. edaphicus sp. nov. were described, and M. egregius was also illustrated and discussed in detail. The species mentioned are very similar to each other under light microscopy. They differ slightly in dimension and number of striae. Only SEM observations showed morphological differences, such as the presence of conopeum or pseudoconopeum.

The family Hahniidae is reported from Thailand for the first time. The genus Hexamatia gen. nov. and two new species, Hexamatia seekhaow gen. et sp. nov. and Hahnia ngai sp. nov., are described and illustrated. DNA sequences are provided for all the species reported here. The phylogenetic position of the novel genus Hexamatia gen. nov. and its relation to Hahnia are discussed.

The family Anthomyzidae (Diptera: Acalyptrata) is recorded from China for the first time based on 11 species, 6 of them new to science. A distinctive new genus Marshallya gen. nov. is described, based on single peculiar species, M. platythorax sp. nov. (both sexes) from Sichuan. Other new species, viz. Amygdalops sevciki sp. nov. (Hainan I.) (both sexes), Epischnomyia tkoci sp. nov. (Sichuan) (male only), Anthomyza ornata sp. nov. (Sichuan) (female only), Anthomyza sulphurea sp. nov. (Yunnan) (both sexes) and Arganthomyza hyperseta sp. nov. (Shaanxi) (male only) are described and illustrated in detail. Male-female association of two Amygdalops species is clarified by means of molecular barcoding and the female of A. bisinus Roháček, 2008 is correctly identifi ed and described. Relationships of all these taxa are discussed. Five species, viz. Amygdalops bisinus (Hainan I.), Epischnomyia merzi Roháček, 2009, Anthomyza cuneata Roháček, 1987, Anthomyza trifurca Sueyoshi & Roháček, 2003 (all from Sichuan) and Arganthomyza versitheca Roháček, 2009 (Shaanxi, Sichuan) are new additions to the Chinese fauna of Anthomyzidae. DNA sequences of the barcoding region of COI have been obtained for 3 species, Amygdalops bisinus, Amygdalops sevciki and Marshallya platythorax. Biology and distribution of all 11 species are discussed. First photographs of living Anthomyzidae from East Asia are presented. Based on knowledge of Anthomyzidae from neighbouring areas the diversity of the Chinese fauna of the family is estimated to include 50-60 species.

The inclusion of Tethlimmena Bates, 1872 in Oxycoleini is reinforced, with the consequent exclusion of Eroschemini Lacordaire, 1868 from the American fauna. Oxycoleus obscurus Júlio, 1997 is transferred to Tethlimmena. Wappesia gen. nov. is described to include Oxycoleus cyaneus Martins & Galileo, 2005, Tethlimmena gahani Gounelle, 1911 (currently, in Oxycoleus), and Tethlimmena gahani tristis Melzer, 1933 (currently, in Oxycoleus as O. tristis). A key to genera of Oxycoleini is provided. Two new species of Oxycoleus are described: O mirabilis, from Mexico (Chiapas) and Guatemala (Baja Verapaz); and O. similis, from Costa Rica (Guanacaste) and Panama (Chiriquí). The male of Oxycoleus flavipes Martins & Galileo, 2006 is described for the first time. Notes on O. laetus Júlio, 1997 are provided.

The Genera of Fungi series, of which this is the sixth contribution, links type species of fungal genera to their morphology and DNA sequence data. Five genera of microfungi are treated in this study, with new species introduced in Arthrographis, Melnikomyces, and Verruconis. The genus Thysanorea is emended and two new species and nine combinations are proposed. Kramasamuha sibika, the type species of the genus, is provided with DNA sequence data for first time and shown to be a member of Helminthosphaeriaceae (Sordariomycetes). Aureoconidiella is introduced as a new genus representing a new lineage in the Dothideomycetes.

A new genus Mirabythus Cai, Shih et Ren, gen. nov. (type species, M. lechrius Cai, Shih et Ren, sp. nov.) and M. liae Cai, Shih et Ren, sp. nov. from the family Scolebythidae are described from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, northeastern China. These findings extend the existence of Scolebythidae to the Early Cretaceous of China, while providing evidence to support Engel and Grimaldi’s hypothesis that the family was widely distributed throughout the Cretaceous. Our two new species with clear venation also provide a comprehensive understanding of the venational changes from the Early Cretaceous to now. A key to the fossil and extant genera of Scolebythidae is provided.
