Comments. This species was originally described ( Michener et al., 2003) on the basis of four males from three different localities in Costa Rica. Two females from one of these localities were considered possibly C. rozenorum and their characters were noted. We now have males and females from a locality in Guatemala as listed above. These females appear to be the same species as the females noted in 2003, supporting the tentative association of sexes. Additional females from localities in Guatemala, San Salvador, and Costa Rica were not taken with males. The data for these specimens are listed above.

Comparisons. The following paragraphs list differences between C. rozenorum and C. inbio .

Male: Caupolicana rozenorum and C. inbio are noteworthy because of the very striking difference in the metatibial shape and setation (see above key and figures 21 and 22 in Michener et al., 2003) but near absence of other differences. The differentiating characters other than the metatibia listed in the original description of the male of C. rozenorum are not reliable. The middle flagellar segments of C. inbio are sometimes about 1.5 times as long as broad as described for C. rozenorum . The punctures on the shining central part of the lower half of the clypeus are more widely scattered in C. rozenorum than in the available specimens of C. inbio , but the difference is not impressive and intergradation is probable. The integument is generally paler in C. inbio than in C. rozenorum ; thus the flagellum is brown to blackish, darker above than below, in C. inbio whereas it is blackish, dark brown below, in C. rozenorum . Moreover, the legs are brown with the metabasitarsus yellowish in C. inbio , whereas the legs including the metabasitarsus are dark brown in C. rozenorum . The setae on the outer surfaces of the meso- and metatibiae are mostly pale in C. inbio , mostly somewhat dusky in C. rozenorum , the darkness varying with the angle of illumination. The supposed difference in dark apices of the mesosomal pile does not exist. An additional apparent difference is in the ocellocular distance, which, although given as 0.15 OD for both species in the original descriptions, seems to be less in C. rozenorum ; this apparently does not apply to all specimens.

Female: Length 17-21 mm (averaging slightly smaller than C. inbio ); forewing length 11-13 mm. Upper interorbital distance about 3 OD; lower interorbital distance about 5 OD; interocellar distance about 1 OD; ocellocular distance about 0.5 OD; other measurements approximately as recorded for C. inbio . Clypeus broadly convex without weak longitudinal depression on each side of weak median longitudinal area as found in C. inbio . Inner metatibial spur with 17 or 18 large teeth (not counting small basal teeth and preapical tooth sometimes present). Integument including metatarsus largely black but pro- and mesofemora and tibiae with brownish areas; pygidial plate medially dark brown. Setae of tarsi largely fuscous although with yellowish reflections. Pile of mesosomal dorsum and T1 usually darker than in C. inbio because of black or dusky apical parts of setae.
