Colletes Latreille, 1802

Note: Synonimc list modified from Michener (2007):

Colletes Latreille, 1802 . Type species: Apis succincta Linnaeus, 1758 .

Evodia Panzer, 1806 . Type species: Apis calendarum Panzer, 1806 (junior synonym of Apis succincta Linnaeus, 1758 ).

Monia Westwood, 1875 (junior homonym of Monia Gray, 1850 ). Type species: Monia grisea Westwood, 1875 .

Monidia Cockerell, 1905 (new name for Monia Westwood (not Gray)).

Colletes (Ptilopoda) Friese, 1921 . Type species: Colletes maculipennis Friese, 1921 (junior synonym of Colletes spiloptera Cockerell, 1917b ).

Colletes (Puncticolletes) Noskiewicz, 1936 . Type species not designated thus not valid.

Rhynchocolletes Moure, 1943 . Type species: Rhynchocolletes albicinctus Moure, 1943 .

Diagnosis: Both sexes of the genus can be fairly easily diagnosed due to the characteristic sigmoidal shape of the vein 2m-cu (also referred to as the second recurrent vein) of the forewing with the posterior part arcuate outwardly, and anterior part slightly curved inwardly ( Fig. 1A ). In some species of Rhynchocolletes Moure, 1943 (sensu Moure et al., 2007, 2012)—the only other genus of Colletinae with representatives in eastern South America—the posterior part of the 2m-cu vein may be slightly arcuate, however, its anterior part is always straight and thus the vein is never sigmoidal ( Fig. 1B ). Hemicotelles Toro & Cabezas, 1977 and Xanthocotelles Toro & Cabezas, 1978 are both endemic to Chile and western Argentina ( Michener 2007; Moure et al. 2007; Ascher & Pickering 2018) and therefore cannot be confused with the Colletes species found in eastern South America. In Colletes , the horizontal surface of the metapostnotum is divided into a series of pits by longitudinal carinae, and is separated from the vertical surface by a transverse carina that may be complete or interrupted medially ( Fig. 1C ). In Rhynchocolletes , the longitudinal carinae and transverse carina are absent, and the horizontal and vertical surfaces of metapostnotum are separated from each other only by a change in slope ( Fig. 1D ).
