Holcopasites pulchellus (Cresson, 1878)


Scientific Name: Holcopasites pulchellus (Cresson, 1878)

Common Name: Nice Cuckoo Nomad Bee


Phileremus? pulchellus Cresson, 1878a: 84 [♀, ♂].

     Lectotype ♀, designated by Cresson (1916: 128). USA, Colorado, by Ridings [ANSP no. 2233].

Neopasites Robertsoni Crawford, 1906: 283 [♀, ♂]. Synonymy by Hurd and Linsley (1972: 22).

     Lectotype ♀, designated by (Linsley 1943a: 131, by mention). USA, Nebraska, Lincoln, 27 August 1902, by M.H. Swenk, on Solidago [♀] [USNM no. 13834].

Neopasites robertsoni pubescens Linsley, 1943a: 131 [♂]. Synonymy by Hurd and Linsley (1972: 22).

     Holotype ♂. USA, New Mexico, Jemex Mountains, Gallina Creek, altitude 8,500 ft., 24 July 1930, by J.C. Chamberlin [CAS no. 4353].


Taxonomic notes: Crawford (1906: 283, 284) did not designate a holotype for N. robertsoni Crawford, 1906 from his type series consisting of a ♀ from Lincoln, Nebraska, and a ♂ from West Point, Nebraska. Linsley (1943: 131) recorded the type locality as Lincoln, Nebraska, corresponding to the ♀ at the USNM [USNM no. 13834], which was recorded as the type locality. As there are only two specimens in the type series, and only one is from Lincoln, this mention by Linsley (1943a: 131) serves as a lectotype designation. Hurd and Linsley (1972: 23) later examined both specimens held in the USNM (the only two specimens examined from Nebraska), but neither was indicated as a type specimen.

DNA Barcode Index Number (BIN): BOLD:AAK6011

Biology: Holcopasites are cleptoparasites of panurgine bees, and in Canada hosts include bees of the genus Calliopsis and Pseudopanurgus (Linsley et al. 1956; Hurd and Linsley 1972; Michener 2007).

Distribution in Canada: Linsley 1943 ["AB" = SK (Prince Albert), as Neopasites robertsoni Crawford); Hurd and Linsley 1972 [AB, SK]; Sheffield et al. 2014 [AB, SK].
