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.
