Abstract
This paper describes and illustrates females and males of two species of Caenohalictus Cameron, 1903: C. sabanaensis n.sp. and C. alexandrei n.sp. Both species are commonly collected in the Savanna of Bogotá, a high plateau in the central region of the Eastern Andes of Colombia. Notes on morphological variations within and among the species, as well as comments on some biological aspects and images of diagnostic structures are provided.
