A new species of Ilyocryptus (Crustacea : Anomopoda) from Bafra Balikgolu, Turkey

A new species of Ilyocryptus Sars from Bafra Balikgölü in Samsun, is described and figured. The shape and armature of Ilyocryptus samsuni n.sp. resembles I. sordidus (Liévin), but I. samsuni n.sp. differs from I. sordidus (Liévin) by the absence of ramified setae along the valve rims, and the occurrence of complete moulting.

Sinodiaptomus sarsi (Rylov, 1923) (Copepoda, Calanoida) in Turkey

This paper reports, describes, and depicts the calanoid Sinodiaptomus sarsi (Rylov, 1923) from Turkey. This species is living in the Devegeçidi dam lake, near Diyarbakır, in the copepods of Arctodiaptomus acutilobatus (G.O. Sars).

A new species of Ilyocryptus (Cladocera: Macrothricidae) from Turkey

A new species of Ilyocryptus Sars from Çildir Lake in Kars is described and figured. In external morphology, Ilyocryptus anatolicus n. sp. resembles partly I. sordidus (Liévin) and I. spinosus Štifter, but it shows several morphological differences in shape and armature of the postabdomen and in the defensive spines on the posterior margin of the carapace.

Eudiaptomus anatolicus n.sp. (Copepoda : Calanoida) from Turkey

Eudiaptomus anatolicus n.sp. displays similarity to E. transylvanicus (Daday, 1890) by possessing an outer marginal spine located proximally on the second exopodite segment of the male right P5, but it differs from this closest species in the presence of a chitinous projection on the second exopodite segment of the male right P5, and in the typical shape of the females thoracic wings. E. transylvanicus (Daday, 1890) has three chitinous processes located on the basipodite segment of the male right P5, whereas Eudiaptomus anatolicus n.sp. has only one small process on this part.This new species is living in lake Poyraz, which is small and shallow. Some cladoceran species, namely, Pleuroxus truncatus (O.F. Müller, 1785), Pleuroxus laevis (Sars, 1862), Pleuroxus trigonellus (O.F. Müller, 1785), Simocephalus exspinosus (Koch, 1841), Eurycercus lamellatus (O.F. Müller, 1785), Alonella excisa (Fischer, 1854), Lathonura rectirostris (O.F. Müller, 1785), Pseudochydorus globosus (Baird, 1843) and two cyclopoid copepods, Megacyclops viridis (Jurine, 1820) and Eucyclops serrulatus (Fischer, 1851) share the same habitat.
