A taxonomic account on the Hylaeus gibbus species-group (Hymenoptera: Apoidea: Colletidae)

Pages 229-249 | Accepted 31 May 2022, Published online: 13 Jul 2022
 

Summary

The Hylaeus gibbus species-group is a notoriously difficult group, whose nomenclature is currently confusing. To clarify the taxonomy of this species group, the most problematic types of the gibbus species-group were examined. The identity of Hylaeus pictus (Smith, 1853) is unclear. The results suggest that two species are grouped under this name in Western Europe and in North Africa: H. pictus and H. purpurissatus (Vachal, 1895), stat. rev. Twelve synonymies are established: Hylaeus praenotatus Förster, 1871 and Prosopis bicarinata Pérez, 1903, n. syn. of Hylaeus gibbus Saunders, 1850; Prosopis nigripes Pérez, 1903, synonym of Hylaeus confusus Nylander, 1852; Prosopis morawitzi Pérez, 1903, Prosopis pereziana Cockerell, 1906, Prosopis pereziana Schulz, 1906 and Prosopis punctiscuta Alfken, 1909, n. syn. of Hylaeus distinguendus Morawitz, 1876; Prosopis stigmorhina Pérez, 1895, Prosopis stigmorhina var. basalis Pérez, 895, Hylaeus denisonae Cockerell, 1931, Hylaeus denisonae ifranensis Cockerell, 1931 and Hylaeus psilurus Cockerell, 1938, n. syn. of Hylaeus purpurissatus (Vachal, 1895). Lectotypes are designated for Prosopis picta Smith, 1853, Hylaeus praenotatus Förster, H. psilurus Cockerell and Prosopis purpurissata Vachal.

Résumé

Mise au point taxonomique sur le groupe d'espèces d'Hylaeus gibbus (Hymenoptera : Apoidea : Colletidae). Le groupe d’espèces d'Hylaeus gibbus est un groupe notoirement difficile et dont la nomenclature est actuellement confuse. Afin de clarifier la taxonomie de ce groupe d’espèces, les types les plus problématiques du groupe d’espèces gibbus ont été examinés. L’identité d’Hylaeus pictus (Smith, Citation1853) est actuellement incertaine. Les résultats suggèrent que deux espèces sont actuellement confondues sous ce nom en Europe occidentale et en Afrique du Nord : H. pictus et H. purpurissatus (Vachal, Citation1895), stat. rev. Douze synonymies sont établies : Hylaeus praenotatus Förster, Citation1871 et Prosopis bicarinata Pérez, Citation1903, n. syn. de Hylaeus gibbus Saunders, 1850 ; Prosopis nigripes Pérez, Citation1903, synonyme de Hylaeus confusus Nylander, 1852; Prosopis morawitzi Pérez, Citation1903, Prosopis pereziana Cockerell, Citation1906, Prosopis pereziana Schulz, Citation1906 et Prosopis punctiscuta Alfken, Citation1909, n. syn. de Hylaeus distinguendus Morawitz, 1876 ; Prosopis stigmorhina Pérez, Citation1895, Prosopis stigmorhina var. basalis Pérez, Citation1895, Hylaeus denisonae Cockerell, Citation1931, Hylaeus denisonae ifranensis Cockerell, Citation1931 et Hylaeus psilurus Cockerell, Citation1938, n. syn. de Hylaeus purpurissatus (Vachal, Citation1895). Des lectotypes sont désignés pour Prosopis picta Smith, Citation1853, Hylaeus praenotatus Förster, H. psilurus Cockerell et Prosopis purpurissata Vachal.
