A contribution to the study of the genus Centromerus Dahl (Araneae: Linyphiidae) in caves of the Balkan Peninsula

Abstract

Centromerus serbicus Deltshev sp. n. is described from specimens previously attributed to C. pr. dacicus. The taxonomic relationships between C. bulgarianus, C. dacicus and C. serbicus sp. n. are discussed and new illustrations are presented. These are closely allied and strictly vicariant species forming a super-species. C. acutidentatus Deltshev, sp. n. is described from caves in Serbia, Bulgaria and Macedonia. This species is closely related to C. obenbergeri Kratochvíl & Miller and to C. gentilis Dumitrescu & Georgescu. The hitherto unknown female from C. obenbergeri is described.
