DIAGNOSIS: Recognizable for the large ♂ sex comb on ta1, with generally 7–8 teeth (range of 5–9: Sulerud and Miller, 1966 ); ta2 with one very small, thin “tooth” barely distinguishable from adjacent setae; male ta1 short, length ~0.80× length of ta2. Male genitalia with base of inner ventral epandrial lobe with furrows and dense microtrichia. Female: apex of oviscapt blunt, ovisensilla all short pegs; spermatheca squat, width 2× the height, with apical indentation. TYPE : Types not found. Mainland and Patterson (1944) did not specify a type specimen, merely stating (p. 33) that “ The stock upon which the description is based originated from specimens collected near Cordoba [ Veracruz ].” SPECIMENS EXAMINED: All in AMNH : Mexico: Desietrode de los Leones, Distrito Federal, VII/29/42, G.B.

From culture 14012-0210.0, DNA seq publ by V. Schawaroch , 2002, 5♂♂ ( ASG 23 ), 1♀ ( ASG 24 ) . DISTRIBUTION: Reported from Colombia (near Bogotá : Hunter, 1964 , 1966 ; Villamizar and Alvarez, 2010 ), Ecuador ( Cotopaxi and Pinchincha: Acurio and Rafael, 2009 ), El Salvador ( Heed, 1957 ), and Mexico ( Mainland and Patterson, 1944 ). It is also reported from Coroico (near La Paz) Bolivia , based on a strain studied by Barrio et al. (1992) . I am unaware of any material from Bolivia . The Coroico strain was the only one of D. tolteca studied by Barrio et al. (1992) , so comparisons with Central American strains and specimens have not been made, genetically or morphologically, and the identity of the Bolivia material has not been verified.
