Gauld & Dubois (2006) synonymized this genus under Schizopyga, but we consider it, after Shaw (2006) and Matsumoto (2016), as a separate genus. Two Afrotropical species of Schizopyga were transferred to Dreisbachia by Varga & Reshchikov (2018), and we found that the Cuban species Schizopyga anseli Fernández-Triana, 2007 and Brazilian S. moreirae Loffredo & Penteado-Dias, 2008 are also distinct members of the genus Dreisbachia (comb. nov.).
The genus Dreisbachia comprises 15 species worldwide. In the New World, two species, D. navajo (Townes) and D. slossonae (Davis), occur in the Nearctic region (record of the former species from Honduras requires verification, see Remarks section under this species), three species occur in Central America, one species is known from Cuba and one species from Brazil. One species, D. avivae Gauld, is found to occur in Mexico.
Nothing is known about host range of any species in the genus.
Dreisbachia navajo is included to the key because it is known from southern USA and probably from Honduras, and therefore has the potential to be found in Mexico.
