description: Plebeia droryana (Friese)
(Figs. 1–5, 15)
Trigona droryana Friese, 1900: 391 (Brazil: 2 workers and 2 males from Espirito Santo, and several workers from Bahia, Drory leg. Type specimens lost).
Diagnosis. The worker of Plebeia droryana is characterized by the following combination of features: the narrow paraocular yellow band, over two thirds as long as the eye (Fig. 1); the uninterrupted yellow band beginning close to the anterior margin of the scutum and continued on the axilla, and all around the posterior margin of the scutellum (Fig. 2); the longitudinal yellowish band on the middle of the clypeus; the sparse punctation of the scutum (punctures between notauli separated by 2 puncture diameters) with shiny integument between punctures; the unbranched hairs on the disk of the scutum; and the reduced malar space, 0.3 times the diameter of the third flagellomere. The male is characterized by the peculiar shape of the fifth metasomal sternum (Fig. 4), with fingerlike lateral lobes twisted latero-posteriorly and bearing a brush of very long plumose setae. The genital capsule and the sixth metasomal sternum are as in figures 3 and 5.
Comments. We have not been able to locate any syntype of P. droryana, and we use the name here as it has been interpreted by J. S. Moure (specimens identified by him in collections). This species has been the subject of numerous studies of anatomy, social behavior, ecology, etc. (Camargo & Pedro 2007). The identity of the species dealt with, at least in most of these works, is illustrated by Cortopassi-Laurino (1978) in her dissertation on the males of P. droryana. Cortopassi-Laurino (1978, plate AB2) presents drawings of the male metasomal sterna, including the diagnostic fifth sternum. This usage is followed here. The designation of a neotype would be desirable, but we have insufficient acquaintance with the distribution and variation of the species in Brazil in order to select such a specimen. Furthermore, this is a delicate matter, taking into account the nearly nine printed columns of references for P. droryana in the catalog of Camargo & Pedro (2007), which deal with multiple aspects of the biology of the species. Plebeia droryana is widespread in the province of Misiones and in the Yungas (including parts of the provinces of Catamarca, Jujuy, Salta and Tucumán), but it does not occur in the intervening Chaco region. Its distribution extends to the south to some localities in the northeast of the province of Buenos Aires (Fig. 15).
