Tribe Paranadopsini trib. nov.

Type genus

Paranadopsis gen. nov. (here described).


Cp elongated and bean-shaped, with curved ventral margin. LV largely overlapping RV, especially along the anterior side. LV with weak anterior and ventral inner list, posterior inner list fully absent. RV without anterior inner list, posteriorly with weakly inwardly displaced selvage. Several limbs with segments reduced in length and/or in chaetotaxy: A1 with four distal segments highly reduced in both length and chaetotaxy; A2 with one short natatory seta (or its accompanying seta) only and reduced length of two distal segments. Idem for Md-palp, Mx1, T1 and T2 (where both setae d1 and d2 are missing). Male unknown.


Because of the structural reduction in both valves (inner lists mostly absent) and the limbs (especially in the A1, but also in most other limbs) it is clear that this new genus and its species do not belong in the tribe Cypridopsini and require a new tribe, which might in time even be elevated to the rank of subfamily.
