Carebara arabara

Specimens were collected from the stomach of Dendrobates frogs in both Brazil and Peru.

Identification
A member of the Carebara escherichi species complex.

Fernández (2004) - This species is easily separated from any other by the near absence of long hairs, with only a very few on the body. The tiny and sparsed foveae of the head, and the finely striated promesonotum also clearly distinguish C. striata.

Distribution based on Regional Taxon Lists
Neotropical Region: Brazil, Colombia, Peru, Trinidad and Tobago.

As Carebara inca with the following differences:

A longitudinal and less narrow stripe, subopaque. Eyes reduced to 1 ommatidium; lamellae of metapleural lobes low; dorsum of head densely sculptured with very small, shallow foveolate punctures, broadly separated; dorsum of promesonotum with dense, fine longitudinal striation mixed with scattered small punctures, sloping face of propodeum densely reticulated. Scapes, dorsum of head, promesonotum and legs with appressed to feebly curved pubescence, denser on head. Body nearly naked of long hairs, with only a few (about 0.05 mm) distributed as follows: four in the clypeal area; two on each frontal lobe; four on promesonotum, none on propodeum, none on legs; two on petiole, two on the postpetiole, two on first tergal dorsum. Body brown, appendages lighter.
