description: Key to the species of Canidia Thomson

2(1). Elytral apices bidentate (Fig. 4 a,b); eyes not margined with dense, uniformly oriented pubescence........................................................................................................ 3
— Elytral apices truncate or rounded (Fig. 4 d–h); eyes of most specimens (except some C. giesberti) distinctly margined with denser, uniformly oriented pubescence ........ 4
3(2). Dorsal surface black; pubescence of pronotum not obscuring surface; no distinct elytral maculae present (Figs. 3 a, 9a). Length 6–12 mm. Costa Rica and Nicaragua .... ............................................................................ cincticornis cincticornis Thomson
— Dorsal surface gray; pubescence of pronotum obscuring most of surface; elytra with two to four post­median black maculae (Fig. 3 b, 9b). Length 8–12 mm. Southern Mexico to Colombia ............................................ cincticornis balteata (Lacordaire)
4(2). Inner margin of scape strongly bicarinate, dorsal carina distinctly, irregularly sinuate (Figs. 5 d,e, 6d); apical process of scape truncate, parallel­sided when viewed from behind, with two equal sized lobes (Figs. 6 a, 7d,e, 8) ............................................... 5
— Inner margin of scape rounded to feebly carinate, dorsal edge evenly curved or rarely, gradually sinuate (Figs. 5 f–i, 6e), apical process of scape rounded, with one or two unequal lobes when viewed from behind (Figs. 6 b,c, 7f–i)............................ 6
