A new species of Oniscus Linnaeus, 1758 (Crustacea: Isopoda: Oniscidea) from northern Spain, with a revised key to members of the genus

Oniscvs ancarenisis from the Sierra de Ancares in northern Spain is described as new. The genus Oniscus now contains four species: ancarensis sp. nov. , asellus Linnaeus, lusitanus Verhoeff and simoni Budde-Lund. The distribution of these species is figured and discussed, and a key is given for their determination.     

Four new species in Lipomyces.

For new species in Lipomyces are described. In terms of nuclear genome comparison the genus Lipomyces comprises three species-clusters. A key to the nine species now assigned to the genus, is given. The delimitation of species by (i) rRNA nucleotide sequence analyses of the 18S and 25S subunits and (II) nDNA homology determinations, do not invariably lead to the recognition of congruent taxa. The family of the Lipomycetaceae, nevertheless provides an illuminative model for phylogenetic studies in terms of more appropriate ribosomal nucleotide sequence analyses of both its teleomorphic and anamorphic members.     

Type specimens and identity of the described species of Conus.

During the third decade of the 19th century, 21 authors described 35 Recent and 11 fossil species of Conus , in 26 separate publications. This brought to 532 the number of species-group names in the genus introduced up to 1830. Only five fossil and seven Recent species are now considered valid. Two additional valid Recent species were described but were given preoccupied names. The remaining nominal species are concluded to be junior or contemporaneous synonyms (19), nomina dubia (11), of infrasubspecific rank (1), or not now considered Conus (1). At present 160 valid species of Conus are recognized from the species-group names described between 1758 and 1830. Of these, 138 are extant and 22 are known only as Tertiary fossils. Nine otherwise valid species, six Recent and three fossil, were described but were given preoccupied names.     

Variation in Encardia (Hym., Ichneumonidae) with a key to the species

Distribution maps are given for all Turkish members of the genus Sunius.     

英国的侧盘菌属:属的概况及大型孢子种的研究(英文)

对侧盘菌属在英国的研究概况进行了评述,研究侧重于Otidea apophysata和O.platyspora两个具有大型子囊孢子的种。同时,对4个错误地用于大型孢子种的名称进行了订正:O. abietina(Pseudotis属的模式种)是含糊名称(nomen ambiguum);O.cochleata也为含糊名称;O. felina是O.alutacea的同物异名,并为后者指定了选模式;将O.umbrina处理为O.bufonia的同物异名。此外,确定了Otidea violacea的分类地位。

An integrative approach to species delimitation in Echinodorus (Alismataceae) and the description of two new species

Summary  Taxonomy of the genus Echinodorus is partially revisited in the light of current understanding of the phylogenetic relationships of the genus. As a result of new taxonomy, the species status of some previously synonymised taxa are restored, other names are synonymised, and some nomenclatural problems unnoticed by previous authors are resolved. Two new species, Echinodorus reptilis and E. emersus are described. The subgeneric divisions of the genus are not accepted, and all subspecific taxa are either rejected or established as species. As a result, 28 species based on a phylogenetic species concept are now recognised in Echinodorus and an identification key to these species is provided.     

On Antarctoscyphus (Cnidaria, Hydrozoa), a new genus of antarctic hydroids and the description of two new species

A new genus of the hydroid family Sertulariidae is established. Several species formerly assigned to the genus Symplectoscyphus Marktanner-Turneretscher, 1890 are included. A review of those species is given, including their main features along with some remarks. Two species new to science are added; the material of those species was collected in the Scotia Sea by the Spanish Antarctic Expedition “Antártida 8611”. Present autecological data are discussed.     

A new species of Amphoropsyche (Trichoptera, Leptoceridae) from Ecuador, with a key to the species in the genus

A new species of Amphoropsyche Holzenthal is described from Ecuador. It is similar to a group of species with dorsomesal processes on the preanal appendages (i.e., Amphoropsyche woodruffi Flint & Sykora, Amphoropsyche refugia Holzenthal, and Amphoropsyche aragua Holzenthal), but can be distinguished from these and other members of the genus by the short, digitate dorsomesal processes on the preanal appendages and the broad lateral processes of tergum X of the male genitalia. A key to males of the 14 species now known in the genus is presented based on characters of the genitalia.     

Redescription of four species of Mehdiella from Testudinidae, with a key to the species and discussion on the relationships among the species of this genus

Four species of the genus Mehdiella Seurat, 1918 are redescribed: M. cristata Petter, 1966 and M. stylosa dollfusi Petter, 1966, parasite of Pyxix arachnoides Bell, 1827 from Madagascar, M. s. stylosa (Thapar, 1925) and M. uncinata (Drasche, 1884), parasite of Testudo graeca Linneaus, 1758, Testudo hermanni Gmelin, 1789 and Testudo horsfieldii (Gray, 1844) from Palaearctic region. Light microscopy and scanning electron microscopy (SEM) studies revealed new informations on the morphology of these species. On the basis of this morphological study, the sub-species Mehdiella stylosa dollfusi and M. s. stylosa are raised to level of species. The position of Mehdiella cristata among the species of the genus Mehdiella and the relationships among the species of the genus Mehdiella are discussed. A key to the eight valid species Mehdiella is given.

Diagnosis of species by the larval phase in the genus Rhipicephalus Koch (Ixodidae) in USSR fauna

The key for identification of species of the genus Rhipicephalus (the fauna of the USSR) on the larval phase is based on the material reared under laboratory conditions. The structure of scutum, organs of gnathosoma and coxae, chaetotaxy of idiosoma and gnathosoma were used for differential diagnosis. In addition morphometric characteristics of the above structures and their proportions were used. A special attention has been given to coexistence of species in sympatric zones, which was revealed or confirmed as a result of identification of species of the genus on larva in the ranges of the fauna of the USSR.
