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).

Es werden ein neues Subgenus, Hylaeus (Pumilaeus) subgen. nov., und vier neue Arten aus verschiedenen Hylaeus-Subgenera beschrieben: Hylaeus (Alfkenylaeus) euphorbiae spec. nov., Hylaeus (Cornylaeus) adamauanis spec. nov., Hylaeus (Deranchylaeus) haladanius spec. nov. und Hylaeus (Pumilaeus) pumilus spec. nov. Als neues Synonym wurde Hylaeus namaquensis Cockerell, 1942 = H. (Alfkenylaeus) stictifrons (Cockerell, 1936) festgestellt; Hylaeus arnoldi (Friese, 1913) wird bestätigt als zugehörig zum Hylaeus-Subgenus Alfkenylaeus (stat. nov.). Die Einordnung der neuen Taxa bedingt eine Reihe von Modifikationen des Systems von Snelling (1985). Die Arten werden an die bestehenden Bestimmungs­tabellen angeschlossen, aber auch für die afrotropischen Hylaeus-Subgenera wird eine neue Tabelle vorgeschlagen. Außerdem werden weitere Daten zur geografischen Verbreitung und zum Blütenbesuch der Arten gegeben.StichwörterAfrica, bee taxonomy, new subgenus, new species, synonyme, identification key, distribution.Nomenklatorische Handlungennamaquensis Cockerell, 1942 (Hylaeus), syn. n. of Hylaeus (Alfkenylaeus) stictifrons (Cockerell, 1936)Pumilaeus Dathe, 2015 (Hylaeus), subgen. n.euphorbiae Dathe, 2015 (Hylaeus Alfkenylaeus), spec. n.adamauanis Dathe, 2015 (Hylaeus Cornylaeus), spec. n.haladanius Dathe, 2015 (Hylaeus Deranchylaeus), spec. n.pumilus Dathe, 2015 (Hylaeus Pumilaeus), spec. n.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.KeywordsAfrica, bee taxonomy, new subgenus, new species, synonyme, identification key, distribution.Nomenclatural Actsnamaquensis Cockerell, 1942 (Hylaeus), syn. n. of Hylaeus (Alfkenylaeus) stictifrons (Cockerell, 1936)Pumilaeus Dathe, 2015 (Hylaeus), subgen. n.euphorbiae Dathe, 2015 (Hylaeus Alfkenylaeus), spec. n.adamauanis Dathe, 2015 (Hylaeus Cornylaeus), spec. n.haladanius Dathe, 2015 (Hylaeus Deranchylaeus), spec. n.pumilus Dathe, 2015 (Hylaeus Pumilaeus), spec. n
