Abstract:
A new ostracod genus and species, Namiotkocypria haysensis gen. et sp. nov., of the subfamily Cyclocypridinae is reported from an artesian well in San Marcos, Texas, USA. The new genus has several unique characteristics that distinguish it from all other genera in the subfamily, including postero-dorsally inclined valves, absence of tubercles in marginal zones of the valves, very short swimming setae on A2, length of aesthetasc ya on A1, asymmetric clasping organs, and differences in the shape of the hemipenis and other cheatotaxial parts. A detailed comparison among related genera of the subfamily is provided. www.zoobank.org/urn:lsid:zoobank.org:pub:42FF41E3-E2FB-4BB6-B9F0-948ED0A0807A.
