Plateros obscurior Pic, 1938, stat.n.

Plateros lacosus var. obscurior Pic, 1938: 160 .

DISTRIBUTION. ‘Tonkin’.

REMARKS. Pic´s [1938] description of this variety of Plateros lacosus Pic, 1926 reads as follows: ‘ Elongatus, niger, thorace rufo, illo antice arcuato, angulis posticis longe prolongatis. Tonkin.’ This variety distinguished by the uniformly black elytra and arcuate anterior pronotal margin may turn out to represent a good species. No type specimens of this taxon were found in the Pic collection at MNHN, and no specimens that would match the above description could be detected in the studied material.
