Type species
Thaicypridopsis longispinosa gen. et sp. nov. (here designated).
Etymology
The genus is named after the country, Thailand, where the new taxon was discovered. The name is a combination between the abbreviated country name(“Thai”) and the existing generic name “cypridopsis”.
Diagnosis
LV overlapping RV. RVi with a row of distinctive submarginal tubercles on postero-ventral part. Valve surface with shallow pitted setae and/or spines. A2 with one strong serrated claw G2. Largest seta on terminal segment of Md-palp apically equipped with hairs. Terminal segment of Mx1-palp cylindrical and elongated, largest setae (bristles) on all three endites with hirsute endings and spatula-shaped apexes. Seta d2 on T2 present (d1 absent), terminal claw with bifurcate ending. Terminal segment of T3 with apical pincer. Caudal ramus reduced, flagellum-like with triangular base.
Differential diagnosis
Thaicypridopsis gen. nov. is generally similar to Zonocypris and Cabelodopsis due to the presence of a strong serrated claw G2 on the A2. It can be distinguished from the other genera of the subfamily Cypridopsinae by the morphology of the RV in the interior view, which appears as a submarginal row of distinctive tubercles on the postero-ventral part, the presence of the robust claw on the terminal segment of the Md-palp, which is apically equipped with hairs, the presence of large bristles with hirsute endings and spatula-shaped apexes on the first to the third Mx1endites and the slightly bifurcated ending of the terminal claw of the T2. These features are diagnostic characters of the new genus and the combination of these aspects has not yet been noted in any other genus of the Cypridopsinae .
Distribution
Thailand (present study).
