Head: Polished (Fig. 7). Mandible with two apical teeth. Eye large, nearly circular, HE 1.44 x WE (Fig. 8). Malar space strigate (Fig. 7). Face above of clypeus with reduced protuberance (Fig. 8). Gena bulging in frontal view, wide in lateral view, WG 1.50 x WTO, genal carina complete (Fig. 8). Lateral of vertex angularly convex in frontal view (Fig. 7). Ocellus large, DAO 1.25 x WTO; ocellar triangle raised in frontal view (Fig. 7). Anterior ocellus aligned in dorsal view of head. Clypeus wide (Fig. 7). Occipital area narrow (Fig. 8). Subocullar groove with inconspicuous carina (Fig. 7). Toruli polished around them (Fig. 7). Antenna inserted at above level of midline of eye (Fig. 7). Antennal segments evenly wide; pubescence subappressed, without some setae outstanding; scape short, scape LS 0.78 x HE; flagellomere I long, LF 1.80 x LP (Fig. 9).

Mesosoma: Thorax impunctate dorsally, strongly raised (Fig. 15). Pronotum wide in lateral view, LPR 0.50 x WTO, with conspicuous fovea in anterior corner. Mosonotum not aligned (Fig. 15). Mesoscutum wide, anterior depression polished, lateral carina complete; notaulus with elongated punctures, straight (Fig. 12). Lateral scutellar region umbilicated; posterior region of scutellum gibbous in profile (Fig. 15). Median region of scutellar groove with large fovea. Metanotum inconspicuous medially. Propodeum shallowly areolate; median region of dorsal propodeum polished; posterior region flat in profile; small ridge posterolaterad of insertion of petiole large (Fig. 15). Mesepimeron weakly scrobiculate. Mesepisternum narrow; anterior region partially areolate; posterior margin evenly areolate; upper region evenly areolate; lower region foveolate, lower region with many foveae, anterior area of lower region with fovea evenly sparse (Fig. 11). Central region weakly concave (Fig. 14). Metapleuron areolate incomplete-umbilicate; metepimeron bulging. Distal region of metafemur not dilated. Tarsal claw with two teeth. Basitarsal projection of hind leg long (Fig. 13) with blunt apex. Wing LFW 3.13 x LM. Basal cell setose. Stigmal vein narrow, WST 0.15 x LST, apex of posterior margin straight (Fig. 10). 1R1 vein expanded distally. Stigmal + 1R1 long (Fig. 10). Stigmal + 1R1 LST 8.50 x WTO. Set of M+CU, 1CUa, 1CUb and 2CU veins sinuous.

Metasoma: Petiole very long, polished dorsally, LPE 1.09 x LST.

Material examined. HOLOTYPE. Male. PANAMA, Darien: Cana, Serrania de Pirre, 1220 m, 07– 09.vi.1996, FIT, J. Ashe & R. Brooks col ( CNCI).

Comments. D. brevis sp. nov. differs from D. elongata sp. nov. by having a subrounded eye; face with reduced protuberance; scape short; torulus inserted above median height eye level; mesepisternum, anterior area of ventral region with fovea of aproximatelly size between them; 1R1 vein expanded distally and basitarsus projection of hind leg long.

Distribution. Panama.

Etymology. The name refers to the short scape length.
