| description | New genetic data on Caucasian troglobiotic shrimps collected from the territory of Russia, Abkhazia and Western Georgia are presented. Based on new genetic data on the marker region of subunit I of cytochrome oxidase of mitochondrial DNA (COXI mtDNA) of Caucasian species and other taxa of European cave shrimps (Troglocaris s.l.) from GenBank (NCBI) database, a new generic structure is presented. Based on a significant genetic divergence of COXI mtDNA subgenera of Troglocaris s.l., namely Troglocaris s.s., Xiphocaridinella and Spelaeocaris, should be considered as separate genera while Troglocaris (Troglocaridella) hercegovinensis (Babić, 1922) is suggested to be transferred within Dinaric genus Spelaeocaris as Spealeocaris hercegovinensis (Babić, 1922) comb. nov. Besides, Troglocaris bosnica shows a significant a genetic difference (at the level of the separate genus) from the remaining representatives of the genus Troglocaris s.s. Moreover, p-distances (COXI) of about 17% are supposed for generic separation within European Troglocaris-related atyid shrimps and 5% for separation of cryptic species within Caucasian Xiphocaridinella. A list of all known taxa of Troglocaris-related atyid shrimps of the European part and a discussion of the general distribution of troglocaridid atyid shrimps in the Balkans and the Caucasus are presented. A new version of divergence events between Dinaric–Caucasian Troglocaris lineages (genera) based on new genetic data is suggested. |
