Abstract
The cleptoparasitic anthidiine bee genus Stelis Panzer is primarily Holarctic in distribution, extending as far south as Costa Rica. A new species of Stelis subgenus Dolichostelis Parker and Bohart is described and illustrated based on females collected in dry forests of the Caribbean region of Colombia. Stelis (Dolichostelis) costaricensis Friese is also recorded from dry forests but in western Colombia. These are the first records of the genus, as currently recognized, for South America. An updated key to the species of Dolichostelis and a synopsis of the diversity and biogeography of the bee fauna from the Caribbean region of Colombia are provided. Based on reports from the literature and data from collections, we provide a checklist consisting of 125 species in 48 genera of five families. The complex composition of this bee fauna parallels that of the flora, with taxa having the following origins or distributions: West Indian, North or Central American, Andean, xeric or temperate South American, and Neotropical widespread. A brief account on the contribution of George Salt to the knowledge of the biology of this Colombian bee fauna is also provided.
