Material examined. HOLOTYPE. Male. COSTA RICA, Hwy. #2 Km 95, 9°36’N 83°44’W, 3200 m, 03–07.iv.1985, H. Goulet & L. Masner col ( CNCI).

Comments. D. glabra sp. nov. differs from the others species by having head inconspicuous punctate; eye elliptical; scape short; mesosoma depressed anterolaterally; mesepisternum vertical and levigate with few foveolation; declivity of propodeum concave in profile and region of basal cell glabrous.

Distribution. Costa Rica.

Etymology. The name refers to the absence of pilosity in the basal cell area.
