Diagnosis

see Bolton & Belshaw 1993:182. The species in this complex correspond to Paedalgus sensu Bolton & Belshaw (1993). The head is slightly narrower anteriorly, there are always eyes present (although reduced to a few ommatidia) and the propodeum is very short. All the species described here match this diagnosis well (but see C. intermedia); it can thus be considered a monophyletic group within Carebara. Of the three groups proposed here, this is the only one that is almost certainly monophyletic, since it includes the African and Sri Lankan species described by Bolton & Belshaw (1993) as well.

Notes

Species of the Neotropical Region subdivide into two subcomplex, based on the size and placement of the foveae in the head. In the first subcomplex (C. brasiliana, C. inca, C. nuda, C. paya and C. pilosa), the foveae are big with the spaces between the inferior foveae less than foveal diameter. In the second subcomplex (C. angulata, C. audita, C. kofana, C. majeri, C. reina, C. semistriata and C. striata) the foveae are small, and the interfoveal spaces are greater than foveal diameter.

C. intermedia stand alone in the group and this species may belong to another group. This species is not included in the key below, but the reader can distinguish it clearly by the species diagnosis.
