Comments. D. elongata sp. nov. differs from of D. brevis sp. nov. by having eye elliptical; face with developed protuberance; scape long; torulus inserted at top height eye level; mesepisternum, anterior area of ventral region with fovea of different size between them; 1R1 vein slender distally and basitarsus projection of hind leg short.

Distribution. Ecuador and Peru.

Etymology. The name refers to the length of the stigmal and 1R1 vein.
