Aspilota signifrons : Fischer 1969b : 254 ; Shenefelt 1974 : 980 ; Marsh 1979 : 222 . Material examined. 1 female ( paratype ), " U.S.А. , Lafayette, Ind., J.M. Аldrich Collector" ( NHMW ). Redescription. Female. Body 1.8 mm ; fore wing 2.1 mm ; hind wing 1.4 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 1.2 × OD; OOL 2.8 × OD. Face 2.4 × as wide as high. Clypeus 3.0 × as wide as high. Paraclypeal fovea reaching halfway distance between clypeus and eye. Mandible 0.9 × as long as its maximum width, widened towards apex. Upper tooth longer than lower tooth; middle tooth long, pointed apically; lower tooth subrounded. Аntenna 19-segmented. First flagellar segment 2.0 × as long as its apical width. Second to tenth segments 1.2–1.3 × as long as their maximum width; 11th to 17th (apical) segments 1.6–1.7 × as long as their maximum width respectively. Mesosoma . In lateral view 1.1 × as long as high. Mesoscutum (in dorsal view) as long as its maximum width. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit present, oval. Prescutellar depression (scutellar sulcus) with distinct median and lateral carinae. Precoxal sulcus present, crenulated, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. 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 4.0 × as long as its maximum width. Wings . Radial (marginal) cell 4.3 × as long as its maximum width. Vein r2 (3-SR) 2.4 × as long as vein cuqu1 (2-SR); vein r3 (SR1) 2.2 × as long as vein r2 (3-SR). Metasoma . First tergite widened towards apex, 2.0 × as long as its apical width, striated. Ovipositor 1.1 × as long as first tergite, shorter than metasoma, 0.7 × as long as hind femur. Colour . Body, legs and antenna from yellowish brown to dark brown. Wings hyaline. Male. Unknown. Comparative diagnosis. This species is similar to D. shannoni (Fischer, 1969) ; differences between both species are shown after the redescription of the latter species.
