Protopolybia collombiana Santos, Silveira & Carpenter, 2015

Material examined. BRAZIL: Acre, Cruz do Sul, 2♀, 23.iii.1982 (Tech, G.M.) (UNESP).

Distribution. Costa Rica, Panama, Colombia, Ecuador, Peru, Bolivia, * Brazil.

Remarks. The nest of P. collombiana consists of a single comb, with an approximately rhomboid-hexagonal shape, averaging 50 mm in length and 35 mm in width. The envelope consists of a single sheet of brown or beige plant fibers with color (Bequaert 1944). Rau (1933) presents almost the same description for P. collombiana (as P. sedula) from Barro Colorado Island, Panama . However, a nest of P. collombiana collected at Tena, Ecuador presents a distinctly green color with some narrow whitish markings (collection code: 901217–18; http://research.amnh.org/pbi-hym/locality/ specimenimages/specimen_thumbnails/ AMNH _HYM%2000000572-0.jpg). This is the first description of this variation in the envelope of the nest.
