Material examined. 1 female (paratype), " U.S.А., Cabin John, Md., Spring.1917, R.M. Fouts ” ( NHMW). Redescription. Female. Body 2.3 mm; fore wing 2.5 mm; hind wing 1.8 mm.

Head. In dorsal view, 1.9 × as wide as median length, 1.5 × as wide as mesoscutum, smooth. Eye in lateral view as wide as temple medially. POL 1.3 × OD; OOL 3.3 × OD. Face 1.9 × as wide as high. Clypeus 3.3 × as wide as high. Paraclypeal fovea very short, not reaching halfway distance between clypeus and eye. Mandible as long as its maximum width, widened towards apex. Upper tooth wide, longer than lower tooth; middle tooth pointed apically; lower tooth subrounded. Аntenna 18-segmented. First flagellar segment 3.0 × as long as its apical width. Second segment 1.7 × as long as its maximum width; third to 14th segments 1.3–1.4×; 15th segment 1.5 ×, and 16th (apical) segment 1.8 × as long as its maximum width respectively.

Mesosoma. In lateral view 1.1 × as long as high. Mesoscutum (in dorsal view) 1.1 × as long as its maximum width. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit absent. Prescutellar depression (scutellar sulcus) with distinct median and with lateral carinae. Precoxal sulcus present, crenulated, reaching anterior margin of mesopleuron. Posterior mesopleural furrow completely crenulated. Propodeum completely sculptured, without median longitudinal carinae. Propodeal spiracles large, its diameter 0.6 × as wide as distance from spiracle to anterior margin of propodeum.

Leg. Hind femur 4.1 × as long as its maximum width.

Wings. Radial (marginal) cell 3.7 × as long as its maximum width. Vein r2 (3-SR) 1.7 × as long as vein cuqu1 (2-SR); vein r3 (SR1) 2.8 × as long as vein r2 (3-SR).

Metasoma. First tergite widened towards apex, 1.5 × as long as its apical width, completely striated. Ovipositor 1.2 × as long as first tergite, shorter than metasoma, 0.7 × as long as hind femur.

Colour. Body and antenna brown to dark brown. Wings hyaline.

Male. Unknown.

Comparative diagnosis. This species is similar to D. longibasis (Fischer, 1969) ; differences between both species are shown after the redescription of the latter species.
