Carebara peruviana

Identification
Fernández (2004) - A member of the Carebara concinna species complex. From Emery’s (1906) description: “Resembles Erebomyrma longii Wheeler in color and sculpture. Petiole and lower part of thorax mostly reddish; fine rugae on head and thorax with indistinct punctures behind rugae. Head is parallel-sided, subrectangular, longer than wide. Antennae short, particularly the scape which is barely thickened. Propodeum armed with blunt tooth. Petiole less wide than postpetiole, petiolar node thick, “scame” shaped, depressed above (not hollowed posteriorly, as in E. longii); postpetiole transverse oval. Wings as in E. longii, the radial cell as in this species, but longer. Length 7 mm, wing length 7 mm”.

It was not possible to examine type material for this species, described on the basis of two females collected in Peru. Judging by Emery’s meager description, it is reasonable to suppose that these females are in some way associated with Carebara longii and therefore having 11-segmented antennae; the author probably would have mentioned it if they were 9-segmented. From the description, it can also be inferred that the petiole posteriorly is unlike that of C. longii or Carebara urichi (concave and with transverse carinae). C. peruviana is apparently different from both. The taxonomic status of this species can only be clarified by observing the type specimens.
