Final Epithet

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

Basionym

Heterorhabdus sinuosus Noël 1970

Description

Species of Retecapsa comprise a cretarhabdid pelaga enclosing a broad central area spanned by an axial cross whose 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, delimiting two pores per quadrant.

Optical Properties

The entire species exhibits first-order, slightly greyish-white interference colours. The pelaga of Retecapsa sinuosa displays inclined extinction and length-fast (-) elongation in plan view under crossed polars.
