Type species

Cyprettadopsis sutura gen. et sp. nov. (here designated).

Etymology

The name is a combination of ‘ Cypretta ’ and an abbreviation of the suffiX of the eXisting generic name ‘ Cypridopsis ’ to refer to the presence of combined characters between Cypretta and cypridopsine genera.

Diagnosis

Cp in lateral view subtriangular, Cp in dorsal view subelliptical; LV and RV in internal view with broad anterior calcified inner lamella, posterior one narrow or absent, LV with one anterior inner list, double posterior inner list, the latter not parallel to valve margin at posteroventral part, RV with large posterior selvage, LV overlapping RV anteriorly and ventrally, complete marginal septa on posteroventral part of both valves, incomplete septa (septa-like structure) on anterior part of both valves, valve surface smooth or set with (shallow) pits; A1 seven-segmented, A2 with undivided penultimate segment, strongly serrated claw G2 and subquadrate terminal segment; terminal segment of Mx1 palp elongated; T1 with a-setae (b-, c- and d-setae absent); T2 penultimate segment undivided, d2 on T2 present (d1 absent); T3 with completely separated terminal segment and very long h1 and h2 setae; CR reduced, with cylindrical base and flagellum-like distal claw.

Differential diagnosis

Based on the reduced CR and the strongly serrated claw G2 of the A2, Cyprettadopsis gen. nov. is similar to genera in the tribe Zonocypridini Higuti & Martens, 2012 ( Cabelodopsis , Thaicypridopsis

and Zonocypris ). The new genus can be principally distinguished by the presence of marginal septa, the undivided penultimate segment of the T2 and the obvious terminal segment of the T3.

Distribution

Thailand (present study).
