Özet

A total of 27 ostracod taxa were collected from 1995 to 2017 from 61 aquatic bodies in the karstic region of Texas (USA) and 1 in Mexico, including from caves, springs, spring-fed pools, and springs/drips in karstic rock-shelters. Among these taxa, Dolerocypris reyesi sp. nov. is a new species collected from a shallow pool connected to the springs above a rock-shelter. Three species (Penthesilenula aotearoa, P. incae, and Vestalenula marmonieri) are reported for the first time from North America. In addition, Typhlocypris cf. prespica and 4 taxa (Microdarwinula zimmeri, Cypridopsis cf. herpestica, Pseudocandona cf. parallela, P. cf. pratensis) are new records of ostracod fauna of the US and Texas, res-pectively. The phylogenetic results based on 31 taxa and 30 morphological characters revealed 4 subgroups belonging to 6 main clustering groups within the family Darwinulidae. Including the new species reported here, the total number of non-marine ostracods in Texas is increased to 115 species. The results indicate that the total number of species is far below the true diversity and richness of the state.
