Aspilota lobidens Fischer 1971: 97 ; Shenefelt 1974: 975; Marsh 1979: 221; Yu et al. 2012.

Material examined. 1 female (holotype), " U.S.А., Marion Co., Fla., 16.xii.1929, Florida Fruit Trap Surv., А.M. Towles" ( NMNH).

Redescription. Female. Body 1.7 mm; fore wing 1.8 mm; hind wing 1.2 mm.

Head. In dorsal view, 1.7 × as wide as median length, 1.3 × as wide as mesoscutum, smooth. Eye in lateral view 2.0 × as wide as temple medially. POL 1.4 × OD; OOL 3.2 × OD. Face 2.1 × as wide as high. Clypeus 3.1 × 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 wide, shorter than lower tooth; middle tooth pointed apically; lower tooth longer than upper tooth, subrounded. Аntenna 20-segmented. First to seventh flagellar segments 2.5 × as long as their apical width; eighth to 16th segments 2.2 ×; 17th segments 2.0 ×; and 18th (apical) segment 2.8 × as long as maximum width respectively.

Mesosoma. In lateral view as long as high. Mesoscutum (in dorsal view) 0.8 × 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, weakly crenulated, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum completely smooth. Propodeal spiracles small, its diameter 0.2 × as wide as distance from spiracle to anterior margin of propodeum.

Leg. Hind femur 4.0 × as long as its maximum width.

Wings. Radial (marginal) cell 3.8 × as long as its maximum width. Vein r2 (3-SR) 1.8 × as long as vein cuqu1 (2-SR); vein r3 (SR1) 2.5 × as long as vein r2 (3-SR).

Metasoma. First tergite not widened towards apex, 0.9 × as long as its apical width, smooth. Ovipositor 2.5 × as long as first tergite, weakly shorter than metasoma, 2.0 × as long as hind femur.

Colour. Body, antenna, mandible and ovipositor brown to dark brown. Mesosoma, metasoma and legs yellow. Wings hyaline.

Male. Unknown.

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