Diagnosis. Sinigarra belongs in the disc-bearing group composed of four other garrain genera, namely Garra , Placocheilus , Discogobio and Discocheilus . These five genera possess a lower lip modified into a mental adhesive disc posteriorly discontinuous from the mental region. Sinigarra is distinguished by having the anterior margin of the mental adhesive disc not modified (vs. modified) into an anteromedian crescentic fold, an upper lip present (vs. absent) but separated from the upper jaw, and indistinct (vs. more prominent) papillae scarcely (vs. densely) scatted over the rostral cap and lower lip or absent ( Fig. 1 ).

Type species. Sinigarra napoense , new species

Etymology. The generic name is made from a combination of the Latin word Sinae (Chinese) and Garra , a generic name used for a group of labeonin species usually with a lower lip modified into a mental adhesive disc and three rows of pharyngeal teeth, in allusion to the presence of a similar disc-like structure. Gender: feminine.
