Subfamily Laphriinae

Twelve Nearctic genera of robber flies are placed in the subfamily Laphriinae and four are placed in the Laphystiinae ( Geller­Grimm 2003) . Information is available on the pupal morphology of Andrenosoma , Lampria , and Laphria . The following key is based on information on Laphria and Andrenosoma from the literature and on the descriptions of Lampria bicolor (Wiedemann) and 7 species of Laphria presented in this paper. Martin & Wilcox (1965) cataloged 4 species of Andrensoma, 3 of Lampria , and 62 of Laphria from North America north of Mexico. Poole (1996) listed 8 species of Andrenosoma , 3 of Lampria , and 63 of Laphria for the Nearctic Region. Cursory information on Andrenosoma and Laphria in Europe is found in Melin (1923), Séguy (1927), Oldroyd (1939), and Musso (1967). Some morphological information on Andrenosoma and Pogonosoma was provided by Krivosheina (1974), but it is not detailed enough for inclusion in this paper. Musso (1978) presented more detailed information on Andresoma bayardi Séguy and A. atra (Linneaus) . His general characteristics for the genus Andrenosoma correspond well to those presented below in the key to genera of Laphriinae . Bullington (1986) illustrated some of the principal characteristics of the pupal cases of Laphria sericea , L. rapax Osten Sacken , L. index , and L. winnemana . His illustrations reveal that the cases have 3–4 posterior antennal processes.
