Adult females up to 2000 µm in length; both valves with apex of anterior and posterior margins below mid-height in lateral view, calcified inner lamella broad anteriorly and posteriorly, extending inwardly by approximately 1/5 of valve length anteriorly and 1/6 posteriorly. A1 third segment with dorsal seta longer than ventral seta. A2 with one natatory seta flanked by four reduced natatory setae on one side, and a longer seta on the other. Males with L5 Rpp and Lpp second segments glove-like and nearly symmetrical, Hp ls protruding further than ms, narrow proximally, widening to rounded latero-distal margin with apex pointing postero-laterally, proximally with lateral rounded protrusion; ms elongated with broad base narrowing to rounded distal margin with apex pointing postero-medially.

First segment with six setae on the dorso-apical margin, three of these setae smooth and of similar length, two slightly longer and hirsute, the most proximal one slightly longest; a seventh seta being the shortest, based more medially than the others, and pointed posteriorly. Second endopodal segment spatulate, distally with three claws and three setae. Third endite with one proximal seta on ventral margin, distally with two strongly developed but smooth claws positioned between seven setae dorsally, and one seta ventrally, all setae on the distal margin of similar length, apart from one seta based slightly more proximal, this seta stout, bent, covered with long stiff setules, and approximately one third of the length of the other setae (not shown in illustrated specimen). Chaetotaxy of endites I and II not elaborated. Respiratory plate with approximately 24 rays, six of these reflexed.
