Lasioglossum glabriventre (Crawford, 1907)


Scientific Name: Lasioglossum glabriventre (Crawford, 1907)

Common Name: Smooth-bellied Sweat Bee


Halictus Vachali Crawford, 1906, in Viereck et al. 1906: 300 [♀]. Preoccupied, not Halictus vachalii Bingham, 1897 (= Nomioides feai Vachal, 1895).

     Holotype ♀. USA, Oregon, Corvallis, 6 June 1898, by [USNM no. 29424].

Halictus glabriventris Crawford, 1907: 21. Replacement name for Halictus vachali Crawford, 1906.


Taxonomic notes: The ♂ has not been described.

Crawford (1906: 300) noted the similarity of his H. vachali Crawford, 1906 and the female of H. kincaidii Cockerell, 1898, both sharing the large, punctured tegulae, but distinguished them by the finer punctures of the mesothorax in the former (and see Crawford 1907: 184). He (Crawford 1907) subsequently revised the group (as Halictus) but did not recognize the males of either.

Though originally described as Halictus vachali Crawford, 1906, this name is preoccupied by Halictus vachalii Bingham, 1897, an unneccessary replacement name proposed by Bingham (1897: 426) based on his assumption that Nomioides feai Vachal, 1895 belonged to the genus Halictus and was thus preoccupied by Halictus feai Vachal, 1895; interestingly, Vachal desribed both species in the same work.

Friese (1916: 561) also named a Chilean species Halictus glabriventris Friese, 1916, but Cockerell (1926: 219) recognized the synonymy and provided the new name Halictus grabrescens Cockerell, 1926; Michener and Wille (1961: 1126) subsequently and incorrectly recognized Halictus glabriventris Friese as a synonym of Lasioglossum aricense (Schrottky, 1910). Though (Eickwort: 1969: 658) correctly recognized the species as a member of the augochlorine genus Halictillus, he also considered Friese’s species valid. Engel (1996: 108) corrected the taxonomy, recognizing Halictillus glabrescens (Cockerell, 1926) as the correct name.

Biology: Hicks (1936: 47) indicated that L. glabiventre nested in fine sand.

Distribution in Canada: Sheffield and Heron 2019 [BC].
