Kempf 1972: 44.    Camponotus crispulusis locally sympatric in Paraguaywith at least two other species in the  C. blanduscomplex, most frequently the similarly-colored  C. rosariensis. Both species share a similarly dense pubsence over most of the body and a common bicoloration consisting of a red head and mesosoma and a dark gaster. However,  C. crispulusis structurally more compact, with shorter appendages and a relatively tall propodeum. In my experience, the easiest character to separate  C. crispulusfrom other bicolored blandus-complex species is the unique pattern of pubescense on the gaster. While all species in the complex show some degree of medial convergence in the appressed setae on the gastric terga, in C.   crispulusthis convergence is extreme, starting on the first gastric tergite (= abd. tergite 3) well ahead of the posterior margin and continuing to the apex of the gaster almost as a visible line. Because of the distinct morphological separation in sympatry between  C. crispulusand other closely-related forms, I find unambiguous the elevation of  C. crispulusto species. Material from Paraguayis a close match to Santschi’s typesfrom Córdoba, although Santschi’s material is somewhat more pubescent. F. Smith’s  C. blandus holotypeworker (BMNH, examined- see discussion under  C. pellitus) from Pará is clearly a different species, as that ant is more gracilethan  C. crispulusand lacks the distinct pubescence.
