Drosophila lowei Heed, Crumpacker, and Ehrman, 1969: 398 View in CoL .

DIAGNOSIS: Very similar to sympatric D. pseudoobscura , but distinguished by the bronzelike sheen on the blackish notum (vs. without sheen in D. pseudoobscura ); ♂ sex comb having fewer teeth on both tarsomeres: ta1 with 4–6 teeth and ta2 with 3–4 teeth (vs. generally 6–9 on ta1 and 5–9 on ta 2 in D. pseudoobscura [ Crumpacker, 1973]); wing distinctly longer than body (vs. shorter); surstylus with row of 9–11 prensisetae (vs. 6–7); posterior margin of hypandrium with pair of prominent, pointed lobes (in D. pseudoobscura this margin barely raised). Acrostichals in 8 rows. Female: Oviscapt with long ovisensilla, lengths ~2× the width (vs. length equal to width); spermatheca subspherical, with apical indentation reaching into internal sleeve (vs. oval, indentation not reaching apex of sleeve).

TYPE: Holotype, ♂: A19.2 / 78 Sept. 1960 / Santa Catalina Mts., Tucson , Ariz., TYPE [in red] [all handwritten by W.B. Heed, from publication: Arizona: Pima Co., Tucson, Santa Catalina Mtns., Mt. Lemmon, W.B. Heed]. In USNM. Examined, not dissected.

SPECIMENS EXAMINED: 9 paratypes: 4 with same data as holotype, labels handwritten . One specimen with simply “A33.6” [handwritten by Heed; from publication: Arizona, Cochise Co., Rustler Park , near Portal , Chiricahua Mtns., VII/15/1961 W.B. Heed] . 5 specimens with simply “2056.1” [handwritten, not Heed’s], 1 with Heed’s writing: 38 mi W Heber, Ariz. VIII/8/50, M.R. Wheeler. All in AMNH, 2 dissected .

DISTRIBUTION: Higher elevations in Arizona and Colorado, probably extending into Sierra Madre Occidental in Mexico. Heed et al. (1969) mentioned that D. lowei can be very common at 7000–9000 ft. (2100 to 2740 m) in pine ( Pinus ) and fir ( Abies ) forests in Arizona, and the species prefers rotting mushroom bait. In Colorado near the Colorado Springs area, D. lowei extended up to 11,400 ft. (3475 m) near Pike’s Peak; it is abundant at higher elevations in Colorado (e.g., Crumpacker, 1973).
