The morphology of the soft body of two unique cephalaspid species, Eоscaphander fragilis Habe, 1952 and Cylichna magna Lemche, 1941, having two gizzard plates in their gizzards has been studied. Taxonomic position of the both species is discussed. The morphology of E. fragilis is described and illustrated for the first time. The species belongs to the monotypic genus which was considered previously as a junior synonym of the genus Scaphander. Feeding of E. fragilis on sponges has been noted. A new monotypic genus, Pseudocylichna gen. nov., has been described for Cylichna magna. Morphological differences of the gizzard plates and gizzard walls of the genera mentioned before have been shown. Both genera have been placed in a new family Eoscaphandridae fam. nov. based on their pair gizzard plates and the division of the gizzard wall into four segments by tendons of the connective tissue.

The Asian monotypic genus Pararhabdophis Bourret, 1934 has long been known from a single holotype of the type species Pararhabdophis chapaensis Bourret, 1934 only. The limited available information hampered the identification of the natricine species. On the basis of eight newly collected specimens of P. chapaensis from the type locality in Sa Pa, Lao Cai Province, Vietnam and from Pingbian, Yunnan Province in southwestern China, the taxonomic position of the genus Pararhabdophis was re-evaluated using both morphological and molecular datasets for the first time. Pararhabdophis chapaensis is nested within the genus Hebius Thompson, 1913 with strong support, and morphologically indistinguishable from the latter genus. As a consequence, we herein synonymize the genus Pararhabdophis with Hebius and discuss about the existing paraphyly of some Hebius species. In addition we report Hebius chapaensis for the first time from China and provide redescription and natural history data of this poorly known species. To facilitate future taxonomic work, an identification key to all known natricine genera from China and Vietnam is also provided.

Based on the morphology of workers, gynes and males, we revise the taxonomy of nominal taxa traditionally included by authors in the fungus-growing ant genus Mycetophylax. Our results indicate that Mycetophylax Emery (Myrmicocrypta brittoni Wheeler, 1907, type species, by designation of Emery, 1913; junior synonym of Cyphomyrmex conformis Mayr, 1884 by Kempf, 1962) includes M. conformis, M. simplex (Emery, 1888), and M. morschi (Emery, 1888) new combination (formerly in Cyphomyrmex), with several synonymies. Mycetophylax bruchi (Santschi, 1916) does not belong to the same genus and is diagnosed, in addition to other characters, by a psammophore arising at the anterior margin of the clypeus. For this species we are resurrecting from synonymy Paramycetophylax Kusnezov, 1956 (Mycetophylax bruchi as type species, by original designation, with M. cristulatus as its new synonym). Myrmicocrypta emeryi Forel, 1907 is the only attine in which females lack the median clypeal seta and have the antennal insertion areas very much enlarged and anteriorly produced, with the psammophore setae arising from the middle of the clypeus and not at its anterior margin as in Paramycetophylax. Notwithstanding its inclusion in Mycetophylax by recent authors, it is here recognized as belonging to a hitherto undescribed, thus far monotypic genus, Kalathomyrmex new genus (Myrmicocrypta emeryi as its type species, here designated). We redescribe workers, gynes and males of all species in the

We establish herein a new genus of Neotropical termites of the subfamily Nasutitermitinae, Sandsitermes gen. nov.. The new genus accommodates a previously described species, Nasutitermes robustus (Holmgren), and is diagnosed by worker characters, including the mandibles, the gut-coiling configuration in situ, and the pattern of cushions and spines of the enteric valve. We characterized and illustrated the imago for the first time and redescribe the soldier and worker castes of Sandsitermes robustus gen. et comb. nov. from syntypes and other samples from eastern Peru. We support our taxonomic decision, presenting morphological differences between the gut pattern and enteric valve of S. robustus and 13 neotropical Nasutitermes species studied for this report, and discuss possible relationships with other neotropical nasute termites.

Size reduction and development of a simplified brachidial structure occurred several times during the long evolution of the Phylum Brachiopoda. Even Recent forms may be micromorphic and paedomorphic with reduced brachidia or none at all. A revision of the Maastrichtian (Late Cretaceous) Terebratella (Morrisia?) suessi Bosquet, 1859 has allowed us to erect a new genus, Jagtithyris gen. nov., because its singular brachidium development does not match any platidiid structure. Such a brachidium has also been observed in another European Late Cretaceous brachiopod, which indicates that this type was not a unique morphological curiosity. This species is the micromorphic Campanian-Maastrichtian Leptothyrellopsis polonicus Bitner & Pisera, 1979, which has brachidial structures in common with Jagtithyris suessi comb. nov., although a number of differences have been observed. The genera Leptothyrellopsis and Jagtithyris gen. nov., are included in a new family, Jagtithyrididae fam. nov. During an ongoing revision of extant brachiopod faunas we have been led to recognize a link between this family and representatives of the genus Simplicithyris Zezina, 1976. The taxonomic position of this peculiar group is also discussed.

Umbyquyra gen. nov., a new Theraphosinae genus with stridulatory bristles on the palpal trocanther of pedipalp trochanter and first leg, is proposed. The genus differs from the other genera with stridulatory bristles on the same segments, Acanthoscurria Ausserer, 1871, Cyrtopholis Simon, 1892, Longilyra Gabriel, 2014 and Nesipelma Schmidt & Kovarik, 1996, by having a palpal bulb with a very short and acuminate embolus and four short keels; separated tibial apophysis; and female spermathecae resembling those of Cyrtopholis, with two seminal receptacles with elongated ducts emerging from a common area. Cyrtopholis palmarum Schiapelli & Gerschman, 1945 and C. schmidti Rudloff, 1996 from Brazil and Acanthoscurria acuminata Schmidt & Tesmoingt in Schmidt, 2005 from Bolivia are transferred to the new genus. The female of Umbyquyra palmarum (Schiapelli & Gerschman, 1945) gen. et comb. nov. and the male of U. schmidti (Rudloff, 1996) gen. et comb. nov. are described for the first time. Cyrtopholis zorodes Mello-Leitão, 1923 is considered a junior synonym of Acanthoscurria gomesiana Mello-Leitão, 1923 and Cyrtopholis meridionalis (Keyserling, 1891) is considered a nomen dubium. Eight new species from Brazil are described: Umbyquyra paranaiba gen. et sp. nov., U. cuiaba gen. et sp. nov., U. araguaia gen. et sp. nov., U. sapezal gen. et sp. nov., U. belterra gen. et sp. nov., U. caxiuana gen. et sp. nov., U. tucurui gen. et sp. nov. and U. tapajos gen. et sp. nov.

The Hepialidae species of Trinidad and Tobago are documented and two species are recognized. The new and monotypic genus Wallacella, gen. n., (Lepidoptera, Hepialidae) is erected to include Phassus guianensis Schaus of Guyana (Wallacella guianensis, comb. n.). The male holotype and genitalia are also illustrated for the first time. Potential generic affinities with Druceiella (Viette) and Pfitzneriana (Viette) are considered. Gymelloxes juliusboosi sp. n. is described from Trinidad and Tobago and compared to its congeneric species. The sternite VIII and male genitalia are diagnostic for this new species. The male holotype is deposited in the collection of the Natural History Museum, London, UK.

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.

AbstractA taxonomic revision of the lichen genus Gymnoderma Nyl. sensu Yoshimura & Sharp (Cladoniaceae) based on an integrative analysis of polyphasic characters supports the segregation of a new genus Cetradonia J.-C.Wei & Ahti in a new family Cetradoniaceae J.-C.Wei & Ahti. The monotypic genus and family are based on Cladonia linearis Evans. In addition, two species are recognized in genus Neophyllis F. Wilson and two species are retained in the genus Gymnoderma Nyl. of the Cladoniaceae.
