Biastes (Neopasites) cressoni (Crawford, 1916)


Scientific Name: Biastes (Neopasites) cressoni (Crawford, 1916)

Common Name: Biastes cressoni


Neopasites cressoni Crawford, 1916: 136 [♂].

     Holotype ♂. USA, California, La Quinta [CAS no. 20830].



The ♀ was described by Linsley (1943: 146) as Gnathopasites (Micropasites) cressoni (Crawford).

The DNA Barcode Index Number (BIN) for this species is BOLD:AAK7839.

The recent phylogeny of Bossert et al. (2020) resulted in the synonymy of the tribes Biastini Linsley and Michener, 1939, Neopasitini Linsley and Michener, 1939, and Townsendiellini Michener, 1944 under Neolarrini Fox, 1895, and the subsequent treatment of Neopasites Ashmead, 1898 as a Nearctic subgenus of Biastes Panzer, 1806, the latter synonymy was proposed earlier by Warncke (1982: 109). Linsley and Michener (1939) and Linsley (1943) provide keys, the latter as Gnathopasites Linsley and Michener, 1939).
