DIAGNOSIS: A very distinctive species from Mexico : ♂ with apical two-thirds of midtibia swollen, having two opposing, parallel combs of long setae (their lengths greater than the width of the tibia), one comb on the dorsal margin of the tibia and another on the ventral margin. Male protarsus with 4 (sometimes 5) teeth on ta1, 3 teeth on ta2. Acrostichals in 6 rows. Oviscapt broad in lateral view; spermatheca without apical indentation ( Felix et al., 1976 , mentioned that the spermatheca is “darker and less convex than in D. pseudoobscura ,” but it is actually more convex). TYPES: Holotype , ♂ , from original description: Mexico : 10 km N Cuernavaca along Highway 95 (between Cuernavaca and Mexico City ), July 29, 1974 , in mixed pine and oak forest. In UCDBM, originally reported to be in the CAS ( Felix et al., 1976 ). The original description also mentions paratypes collected in the same locality but in 1975, as well as in Lago Patzcuara, Michoacan and Parque Nacional El Chico, near Pachuca, Hidalgo , Mexico . Felix et al. (1976) reported that paratypes were also deposited in the AMNH, but which were never here. All paratypes are in the UCDBM. SPECIMENS EXAMINED: 2♂ , 1♀ : Mex [ico] Morelos , Cuernavaca , VII 29 1974 , Th. Dobzhansky / PARATYPE Drosophila cuauhtemoci Felix & Dobzhansky ( ASG 38 ♂ , ASG 39♀ ). In UCDBM . DISTRIBUTION: Known only from south central Mexico . COMMENTS: It would be interesting to eventually observe how the male uses the midleg brushes, probably in courtship.
