Studies on the systematics and taxonomy of the genus Hylaeus F. (9) Supplement to the taxonomy and distribution of Afrotropical Hylaeus F. species (Hymenoptera: Anthophila, Colletidae).

Abstract

A new subgenus, Hylaeus (Pumilaeus) subgen. nov., and four new species of different subgenera of Hylaeus are described: Hylaeus (Alfkenylaeus) euphorbiae spec. nov., Hylaeus (Cornylaeus) adamauanis spec. nov., Hylaeus (Deranchylaeus) haladanius spec. nov. and Hylaeus (Pumilaeus) pumilus spec. nov. The synonymy of Hylaeus nama­quensis Cockerell, 1942 with H. (Alfkenylaeus) stictifrons (Cockerell, 1936) syn. nov. is stated; Hylaeus arnoldi (Friese, 1913) is confirmed as a species of the Hylaeus subgenus Alfkenylaeus (stat. nov.). The placement of the new taxa requires a series of modifications to the classification by Snelling (1985). The species are inserted in the existing identification keys, and a new key to the Afrotropical subgenera of Hylaeus is presented. Additional data on the geographical distribution and floral visits of species are given.
