Eurhopalothrix spectabilis

Identification
This is a highly distinctive species. The clypeus is smooth, highly polished and glassy; the face is uniformly punctate but with the same highly polished integument; the basal lobes of the scape are very strongly developed; the ventral surface of the head has a pair of longitudinal carinae, particularly prominent in the queen; the face, dorsal mesosoma, petiole, postpetiole, and first gastral tergite are completely devoid of specialized setae and ground pilosity is similarly obsolete; the propodeal spines are acute but still subtended by a broad foliaceous crest; and the posterior margin of the petiolar node is strongly carinate. The holotype dealate queen was collected in a Berlese sample from Santa Catarina State. Subsequently Kempf described the worker from several series collected by K. Lenko in Barueri, São Paulo. These were from "sifted nest material of Camponotus rufipes (F.)," from three different nests. (Longino 2013)
