Colletes rugicollis Friese, 1900

Colletes rugicollis Friese, 1900 . Lectotype ♀ at ZMB (designated by Moure & Urban [2002]), photographs examined ( Fig. 17 —see comments below). Type locality: Bolivia, La Paz, Jungas.

Colletes punctatissimus Schrottky, 1902 . Holotype ♂ at MZUSP, not examined (but see comments below). Type locality: Brazil, São Paulo, Jundiaí. Synonym proposed by Moure (1944).

Diagnosis. Colletes rugicollis is very similar to C. argentinus , but can be distinguished from it by the characters emphasized in the diagnosis for the latter (see above).

♀/♂—Labrum black, without punctures but with longitudinal sulci; clypeus without mid-longitudinal depression; hypostomal carina forming a high, concave lamella; mid posterior region of mesoscutum homogeneously and densely punctate, with no smooth area; ventral region of mesepisternum, near ventral end of episternal groove, ordinary, lacking a distinctive swollen area delimited by short and dense pilosity; marginal zone of T1 convex.

♀—Malar area 0.3 times as long as interocellar distance; clypeus coarsely rugose; F1 slightly longer than its apical width; gena, behind the upper eye margin, flat, not carinate posteriorly; anterolateral angle of pronotum triangular, shorter than its basal width; pilosity on mesoscutum composed of a mix of black and white hairs; pilosity on mesepisternum, ventrally, sparse; fore coxa without spine; punctation on T1 coarse and dense.

♂—Malar area 0.45 times as long as interocellar distance; clypeus with rugae; F1 slightly shorter than its apical width; gena, behind the upper eye margin, flat, not carinate posteriorly; anterolateral angle of pronotum triangular, shorter than its basal width; pilosity on mesoscutum composed of a mix of black and white hairs; pilosity on mesepisternum, ventrally, sparse; fore coxa without spine; inner spur of hind tibia serrate; punctation on T1coarse and dense, generally more sparsely punctate on disc; S7 as illustrated in Figures 6 K, 6L; genitalia as illustrated in Figures 7 K, 7L.

Comments. The synonymy between C. rugicollis and C. punctatissimus was established by Moure (1944), who compared the holotype of C. punctatissimus with a male collected in copula with a female identified by him as C rugicollis . Unfortunately, two attempts each to locate the holotype of C. punctatissimus in MZUSP and in DZUP were unsuccessful. Rasmussen et al. (2009) were also unable to find it. Thus, we are following Moure (1944) in his opinion, but C. punctatissimus might also be a senior synonym of C. argentinus , which has been also synonymized with C. rugicollis by Moure & Urban (2002), an opinion still sustained by Moure et al. (2007).

In his description of C. rugicollis, Friese (1900) mentions three females, two from Jungas [Yungas], Bolivia, sold by Staudinger, and one from “S. Cruz-Blumenau”. Moure (according to Moure & Urban 1992) examined one female from Yungas in ZMHB and, in that paper, they designated it as lectotype (see Fig. 17 ). It is not clear to us whether or not the second female from that locality and the one from “S. Cruz-Blumenau” are lost, but they could not be found in ZMHB, neither by Dr. Frank Koch, Hymenoptera curator of that museum, nor by Mr. Igor Coelho, during a visit to that museum, nor by Mrs. Viola Richter, the collection manager. In the preparation of a paper on H. Friese ( Rasmussen & Ascher 2008), Dr. Claus Rasmussen (pers. comm.) was able to find only one of the three syntypes in the ZMHB, presumably the specimen examined by Moure and designated by him as the species’ lectotype.
