Abstract

 

Cis renominatus Sandoval-Gómez, Lopes-Andrade & Lawrence, 2014, and Paratrichapus javanus (Pic, 1937) were originally described in the genus Xylographus Mellié, 1847. Their original descriptions are anecdotal and do not provide information on the morphology of male abdominal terminalia, which is essential for accurate identification of ciid beetles. Our aim is to redescribe C. renominatus and P. javanus based on careful examination of lectotypes and paralectotypes, and also on additional specimens of C. renominatus identified by us. The most remarkable feature of C. renominatus is the morphology of male genitalia, with penis about twice as long as tegmen, very slender, subparallel-sided, with apex hook-shaped and base spatula-shaped. Paratrichapus javanus is the largest species of the genus (length at least 3.50 mm) and is characterized by its very expanded and rounded metatibiae that bear about 25 spines, and by the anterocephalic edge of males bearing two tubercles with two tufts of bristles between them.
