Bifurgaster,a new genus of Ascothoracida (Crustacea: Maxillopoda) parasitic in deep water asteroids

A new genus of ascothoracid, Bifurgaster gen. nov., has been found parasitizing brisingid asteroids Freyella spp. The genus comprises two species, B. freyellae sp. nov. and B. kermadeca sp. nov., from the north-east Atlantic Ocean and south Pacific Ocean respectively, at depths of over 4000 m. The genus is characterized by the adult female having a bilobed mantle within which is a reduced main body with little or no segmentation. The only appendages are the first antennae and second maxillae. Each lobe of the mantle contains two branches of the gut and ovary and a distinctive gland. Males and larvae of B. freyellae are described. The genus is placed in the family Dendrogastridae, and is thought to be intermediate between Ulophysema and Dendrogaster.

Nephtyidae (Polychaeta: Phyllodocida) of Australia: new species from the North West Shelf,and a key to Australian species

Five species of Nephtyidae new to Australia are described from the North West Shelf, and a key to the 18 known species of Australian nephtyids is given.

Difficulties in the clear definition of Aglaophamus, Micronephthys and Nephtys indicate the need for systematic revision of the family.     

Contributions to the knowledge of the genera Haemerophygus Baudi, 1876 and Ceratanisus Gemminger, 1870 (Coleoptera: Tenebrionidae: Ceratanisini) in the Anatolian region

Previously known species of the genus Ceratanisus Gemminger, 1870 are studied, based on a comparison of specimens.
