Final Epithet

Retecapsa sinuosa (Noël, 1970) Varol, n. comb.

Basionym

Heterorhabdus sinuosus Noël 1970

Description

Species of Retecapsa comprise a cretarhabdid pelaga sloping towards the central area, composed of inclined segments that are typically weakly clockwise-imbricated, though rarely non-imbricate, and a distally arched central area characterised by an axial cross. The arm tips overlap the pelaga and bear a distal process, a defining feature of Retecapsa sinuosa.

The intercross area contains a single pointed lateral bar that delimits two pores per quadrant.
