Species Notes

Viereck (1904: ) did not specifiy a holotype among the type material of Pterandrena nudiscopa, with specimens collected on at least four separate days, and two years. As such, LaBerge’s (1989: 22) mention of a holotype with a catalogue number and date constitutes a valid lectotype designation. However, he incorrectly records the date as 2 April 1897; this is assumed to be 1899 based on Viereck’s original listing. LaBerge (1989: 18) placed A. opaciventris Cockerell into synonymy under A. angustitarsata, but indicated that he was unable to find the type material; he mentioned it should be at Pomona College at Claremont (no. 197) (LaBerge 1898: 22). It was subsequently reported at CAS (Gusenleitner and Schwarz 2002: 85). Linsley (1951: 1068), Hurd (1979: 1829), Gusenleitner and Schwarz (2002: 85) treated Andrena huardi Viereck as a valid species, though provide no justification on this status; unfortunately, LaBerge (1989) did not include this species in his treatment of the subgenus in the Nearctic, though Kathirithamby and Taylor (2005) treated it as a subspecies of A. angustitarsata in as a host to strepsipteran parasites, though bee nomenclature in that work is treated poorly. LaBerge (1989) also treated Andrena opacissima as a new synonymy of A. angustitarsata, but indicated that this could not locate the holotype.
