Drosophila tolteca Patterson and Mainland View in CoL , in Mainland and Patterson, 1944: 32.

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. Mainland 1342.1, 1♂, 1♀. EL SALVADOR: San Salvador / Jan. 21, 1954, W.B. Heed, 1♂; Volcan Santa Ana , 5670 ft., 20.7a / Nov. 1953, W.B. Heed, 1♂; Volcan Boqueron , 4500 feet, 91.16 / Feb 25, 1954, W.B. Heed, 1♂. NICARAGUA: 11 klm N Matagalpa 57.22 / Santa Maria de Ostuma / June 1954, W.B. Heed, 1♂. 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.
