Th e South American species of the rare bee genus Chlerogella Michener (Halictinae: Augochlorini) are
revised, completing the study of the genus. Chlerogella diversity is signifi cantly expanded beyond the fi ve
previously described South American species of Chlerogella azurea (Enderlein) comb. n., C. nasus (Enderlein),
C. mourella Engel, C. octogesima (Brooks and Engel) comb. n., and C. buyssoni (Vachal). Twenty-two
new species are described – C. agaylei sp. n., C. arhyncha sp. n., C. borysthenis sp. n., C. breviceps sp. n.,
C. cochabambensis sp. n., C. cooperella sp. n., C. cyranoi sp. n., C. dolichorhina sp. n., C. elysia sp. n.,
C. eumorpha sp. n., C. euprepia sp. n., C. hauseri sp. n., C. hypermeces sp. n., C. materdonnae sp. n., C.
oresbios sp. n., C. picketti sp. n., C. rostrata sp. n., C. silvula sp. n., C. terpsichore sp. n., C. tychoi sp. n.,
C. vachali sp. n. C. xuthopleura sp. n. – and the distribution of the genus is expanded beyond Perú and
Ecuador to include Bolivia, Colombia, and Venezuela. Th e female of C. azurea is described for the fi rst
time while the placement of Halictus buyssoni Vachal in Chlerogella is considered tentative, following the
usage of previous authors, as the holotype and sole specimen is untraceable. Th e genus is newly diagnosed
based on a greater understanding of variation in malar length across the species and a dichotomous key is
provided. New fl oral records for species of Chlerogella include Psychotria pongoana Standl. (Rubiaceae) and
a putative record on Phragmopedium longifolium (Warsz. & Rchb.f.) Rolfe (Orchidaceae).
