New species of the genus Troglocheles (Acari : Prostigmata : Rhagidiidae) from Oetztal Alps, Tyrol, with a key to adult species of the genus

摘要

Two new species of rhagidiid mites are described from Oetztal Alps, Tyrol, Troglocheles archetypica n. sp. and T. aggerata n, sp. Their interspecific relationships are discussed acid two new species-groups, T. strasseri and T. vornatscheri, are defined. A key to the known adult species of the genus Troglocheles Zacharda is given. Phylogenetic and evolutionary relationships among the known talus- and cave-dwelling species of this genus are briefly outlined, including the possibilities of sympatric versus allopatric speciation.
