Abstract. Rhomphaea hyrcana (Logunov & Marusik, 1990) is recorded for the first time for araneofauna of Turkey. The characteristic features and photographs of this newly recorded species are presented.

Theridiidae is one of the large spider families with 2462 spe-cies in 122 genera and has a worldwide distribution (World Spider Catalog, 2016). Genus Rhomphaea L. Koch, 1872 is rep-resented by 33 species in the Afrotropical, Nearctic, Neotropical Oriental and Palaearctic regions. Until now, 79 cobweb spider species belonging to 31 genera have been re-corded from Turkey (Bayram et al., 2016). This paper deals with the characteristic features and distribution of Rhom-phaea hyrcana (Logunov & Marusik, 1990) adding a new ge-nus and species to the araneo-fauna of Turkey. The specimens of R. hyrcana were collected on bushes with a sweep net during the daytime.

The genus Rhomphaea are mainly known as araneophagic species and kleptoparasitic spiders, which steal or feed on prey captured by other spiders. The female R. hyrcana in this paper were collected with sweep net on bushes which con-tain numerous Linyphia triangularis (Clerck, 1757) webs. It is observed that the species shaked and moved on the ground with lifting up its abdomen and bent ventrally the distal tip to proximal tip of the long abdomen. In the present paper
