A new Chilean species of the bee genus <i>Anthophora</i> Latreille (Hymenoptera: Apidae)

Three species of the diverse bee genus Anthophora Latreille have been known to occur in Chile: Anthophora ( Mystacanthophora ) arequipensis Brèthes, A . ( M .) incerta Spinola, and A . ( M .) paranensis Holmberg. A fourth species is here described and fi gured from two distinctive females from north-central Chile. Anthophora ( M .) brunneipecten sp. n. is most easily confused with the darker females of A . arequipensis ( sensu the polymorphic concept of Brooks, noting, however, that this is likely several distinct species with synonyms needing resurrection, most notably A. escomeli Brèthes) but can be distinguished by the largely dark fuscous to dark brown setae of the head (rather than largely white in A . arequipensis ) and the presence of a clypeal pecten (absent in A . arequipensis ), among other differences.
