Material examined. 1 female (holotype), " U.S.А., Florida, Gainesville , vii.1953, C.N. Patton Coll., Cat. No. 10699b" ( NMNH).

Redescription. Female. Body 2.1 mm; fore wing 1.4 mm; hind wing 0.9 mm.

Head. In dorsal view, 1.2 × as wide as median length, 1.6 × as wide as mesoscutum, smooth. Eye in lateral view 0.8 × as wide as temple medially. POL 1.3 × OD; OOL 3.1 × OD. Face 1.8 × as wide as high. Clypeus 2.8 × as wide as high. Paraclypeal fovea short, not reaching halfway distance between clypeus and eye. Mandible as long as its maximum width, widened towards apex. Upper tooth rather wide, longer than lower tooth; middle tooth long, pointed apically; lower tooth, subrounded. Аntenna 13-segmented. First and second flagellar segments 2.1 × as long as its apical width; third to ninth segments 1.8 × as long as its maximum width; tenth segment 1.4 × as long as its maximum width, and 11th (apical) segment 1.8 × as long as wide respectively.

Mesosoma. In lateral view 1.6 × as long as high. Mesoscutum (in dorsal view) about 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 without lateral carinae. Precoxal sulcus present, crenulated, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum completely smooth. Propodeal spiracles large, its diameter 0.6 × as wide as distance from spiracle to anterior margin of propodeum.

Leg. Hind femur 2.5 × as long as its maximum width.

Wings. Radial (marginal) cell 5.4 × as long as its maximum width. Vein r2 (3-SR) 1.4 × as long as vein cuqu1 (2-SR); vein r3 (SR1) 6.5 × as long as vein r2 (3-SR).

Metasoma. First tergite weakly widened towards apex, 2.6 × as long as its apical width, smooth. Ovipositor 0.7 × as long as first tergite, shorter than metasoma, 0.7 × as long as hind femur.

Colour. Head and antenna dark brown. Body, legs and pterostigma light brown to yellowish brown. Wings hyaline.

Male. Unknown.

Comparative diagnosis. This species is similar to D. armillariae (Fischer, 1969) and D. lobidens (Fischer, 1971) , but differs from them in having the mesosoma in lateral view 1.6 × as long as high (1.0–1.1 × in D. armillariae and D. lobidens ), eye in lateral view 0.8 × as wide as temple medially (1.4 × in D. armillariae and 2.0 × in D. lobidens ), head in dorsal view 1.2 × as wide as median length (1.7–1.8 × in D. armillariae and D. lobidens ), clypeus 1.8 × as wide as high (2.7 × in D. armillariae and 3.1 × in D. lobidens ), hind femur 2.5 × as long as its maximum width (4.5 × in D. armillariae and 4.0 × in D. lobidens ), first metasomal tergite 2.6 × as long as its apical width (0.8–0.9 × in D. armillariae and D. lobidens ), propodeal spiracles rather large, its diameter 0.6 × as wide as distance from spiracle to anterior margin of propodeum (small in D. armillariae and D. lobidens , 0.3 and 0.2 × respectively).
