A new species of the snakefly genus Inocellia Schneider, 1843 from northeastern India is described: Inocellia indica sp. nov. The new taxon represents the second species of Raphidioptera from the northeastern part of the Indian Subcontinent and appears to be closely related to I. bhutana Aspöck, Aspöck & Rausch, 1991 from neighboring Bhutan.

A new hoverfly species, Cheilosia barbafacies Vujić & Radenković sp. n. (Diptera, Syrphidae), is described and distinguished from the closely related species Cheilosia pascuorum Becker, 1894, based on material collected from the mountains of the Balkan Peninsula. Diagnostic characteristics and an identification key for the members of the proxima group of Cheilosia s. str., including the new tax...

A new species of Anthaxia Eschscholtz, 1829 endemic to Jordan, Anthaxia (Haplanthaxia) nabataea sp. nov., is described and illustrated. The new taxon is compared to its most similar species, and data about its distribution, bionomy and taxonomic position are given, together with some notes on the Anthaxia (Haplanthaxia) winkleri species-group.

a total of 162 species (s) of rotifera belonging to 40 genera and 20 families examined from loktak lake, an important floodplain lake of northeast india (nei), is one of the richest assemblages of the taxon known from the indian sub-region. it merits biodiversity value as ~40.0% and ~62.0% of species recorded from india and nei, respectively. one species is new to india, 23 species are new to m...

The genus Phyllactinia is one of the members of Erysiphaceae (Erysiphales, Ascomycota) which parasitize several host plant families. This taxon is well characterized by having acicular appendages with bulbous swelling at the base and penicillate cells which are outgrowth of some ascoma wall cells. A number of challenges exist to distinguish species assigned to this taxon. This is because of a f...

Large numbers of diatom taxa are currently being described each year and molecular data sets are providing phylogenetic evidence that challenges the traditional systematic arrangement of diatoms, but is such information being integrated into the classification? The traditional diatom classification originated as an aid to identification rather than as an arrangement expressing perceived relatio...

BACKGROUND The 'Solnhofen Limestone' beds of the Southern Franconian Alb, Bavaria, southern Germany, have for centuries yielded important pterosaur specimens, most notably of the genera Pterodactylus and Rhamphorhynchus. Here we describe a new genus of non-pterodactyloid pterosaur based on an extremely well preserved fossil of a young juvenile: Bellubrunnus rothgaengeri (gen. et sp. nov.). ME...

The holotype and only known specimen of the enigmatic small reptile Elachistosuchus huenei Janensch, 1949 from the Upper Triassic (Norian) Arnstadt Formation of Saxony-Anhalt (Germany) is redescribed using μCT scans of the material. This re-examination revealed new information on the morphology of this taxon, including previously unknown parts of the skeleton such as the palate, braincase, and ...

Enchodontoidei are extinct marine teleost fishes with a long temporal range and a wide geographic distribution. As there has been no comprehensive phylogenetic study of this taxon, we performed a parsimony analysis using a data matrix with 87 characters, 31 terminal taxa for ingroup, and three taxa for outgroup. The analysis produced 93 equally parsimonious trees (L = 437 steps; CI = 0.24; RI =...

We describe a small hylid frog species with a highly distinctive tadpole from the Kimberley region of northern Western Australia. The new taxon is morphologically very similar to Litoria meiriana but can be differentiated using a combination of adult and larval morphology and male calls. Tadpoles of the new taxon can be readily differentiated from those of L. meiriana by their unique black, gol...
