Key to the species of Canidia Thomson View in CoL
1. Pronotum and each elytron with three narrow, longitudinal vittae of gray, appressed pubescence, separated by narrow, nearly glabrous black regions ( Figs. 1 View FIGURE 1 a, 9c). Length 7.5–8.5 mm. Guerrero, Mexico................................ turnbowi View in CoL , new species
— Pronotum and elytron not as above, without aformentioned vittae, nearly completely covered in pubescence, without longitudinal narrow vittae of gray pubescence separated by nearly glabrous, narrow, black regions ........................................................ 2
2(1). Elytral apices bidentate ( Fig. 4 View FIGURE 4 a,b); eyes not margined with dense, uniformly oriented pubescence........................................................................................................ 3
— Elytral apices truncate or rounded ( Fig. 4 View FIGURE 4 d–h); eyes of most specimens (except some C. giesberti View in CoL ) 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 View FIGURE 3 a, 9a). Length 6–12 mm. Costa Rica and Nicaragua.... ............................................................................ cincticornis cincticornis Thomson View in CoL
— Dorsal surface gray; pubescence of pronotum obscuring most of surface; elytra with two to four postmedian black maculae ( Fig. 3 View FIGURE 3 b, 9b). Length 8–12 mm. Southern Mexico to Colombia............................................ cincticornis balteata (Lacordaire) View in CoL
4(2). Inner margin of scape strongly bicarinate, dorsal carina distinctly, irregularly sinuate ( Figs. 5 View FIGURE 5 d,e, 6d); apical process of scape truncate, parallelsided when viewed from behind, with two equal sized lobes ( Figs. 6 View FIGURE 6 a, 7d,e, 8) ............................................... 5
— Inner margin of scape rounded to feebly carinate, dorsal edge evenly curved or rarely, gradually sinuate ( Figs. 5 View FIGURE 5 f–i, 6e), apical process of scape rounded, with one or two unequal lobes when viewed from behind ( Figs. 6 View FIGURE 6 b,c, 7f–i)............................ 6
5(4). Vestiture, except for annulate antennae, concolorous, uniform; dorsal surface including scape and pronotum covered with pale gray pubescence ( Figs. 3 View FIGURE 3 c, 5d). Pronotal disk finely, sparsely punctate ( Fig. 9 View FIGURE 9 d). Length 10–14 mm. Westcentral Mexico... ...................................................................................................... canescens (Dillon) View in CoL
— Vestiture multicolored, variable; dorsal surface of scape mottled ( Fig. 5 View FIGURE 5 e), pronotum typically with median area darker than sides resulting in a vittate pattern.
