Cardiomya cleryana auct., non d’Orbigny, 1842 – Barroso et al. 2016: in part.
Material examined
BRAZIL – Amapá state • [1v]; northwest of Amazon Canyons; 03°37′00″ S, 50°01′00″ W; 72 m depth; 08 May 1971; GEOMAR III, stn 193; CMPHRM 3681.
Description
Shell small (length 7.8 mm; height 6.1 mm). Shell flank elliptical, umbones blunt. Anterodorsal margin forming a shoulder, anterior margin truncated, ventral margin rounded, crenulated. Rostrum very short, truncated, posteroventral sinuation shallow, posterodorsal margin curved upwards, extending a little above the umbones. External sculpture of 22 radial ribs, less spaced towards the anterior region, the four strongest and most widely spaced ribs at the posterior end of the shell flank; rostrum with four radial lines.
Geographic distribution
Brazil, Amapá state, northwest of Amazon Canyons, 72 m.
Remarks
Part of the specimens listed as Cardiomya cleryana in Barroso et al. (2016: 6) (CMPHRM 3681) are here reassigned to Cardiomya sp. 1.
Cardiomya surinamensis van Regteren Altena, 1971 is similar to Cardiomya sp. 1, but can be distinguished from it by its weak radial ribs, which vanish towards the anterior region, and the wide rostrum, devoid of radial ornamentation.
