( Figs 17 , 18 )

Aspilota foliformis Fischer 1969a: 108 ; Shenefelt 1974: 972; Marsh 1979: 221; Yu et al. 2012.

Material examined. 1 female (holotype), " U.S.А., Langdale, Chambers, Co., Аlab., H.H. Smith Coll." ( NMNH). Redescription. Female. Body 2.6 mm; fore wing 2.0 mm; hind wing 1.5 mm.

Head. In dorsal view, 2.0 × as wide as median length, 1.4 × as wide as mesoscutum, smooth. Eye in lateral view 1.9 × as wide as temple medially. POL 1.1 × OD; OOL 3.3 × OD. Face 1.7 × as wide as high. Clypeus 3.5 × as wide as high. Paraclypeal fovea reaching halfway distance between clypeus and eye. Mandible 1.5 × as long as its maximum width, widened towards apex. Upper tooth wide, shorter than lower tooth; middle tooth short, pointed apically; lower tooth, subrounded. Аntenna 17-segmented. First flagellar segment 3.5 × as long as its apical width. Second and third segments 2.2 × as long as their maximum width; fourth to 14th segments 1.8–2.0 × as long as their maximum width, and 15th (apical) segment 2.6 × as long as wide respectively.

Mesosoma. In lateral view 1.1 × as long as high. Mesoscutum (in dorsal view) 0.9 × as long as its maximum width. Notauli mainly absent on horizontal surface of mesoscutum. Mesoscutal pit present, elongate. 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 mainly smooth with complete median longitudinal carinae and with very short subtransverse carinae emerging from median carina, and far distant from propodeal edges. Propodeal spiracles small, its diameter 0.3 × as wide as distance from spiracle to anterior margin of propodeum.

Leg. Hind femur 4.2 × as long as its maximum width.

Wings. Radial (marginal) cell 4.2 × as long as its maximum width. Vein r2 (3-SR) 2.2 × 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, 3.9 × as long as its apical width, smooth. Ovipositor 0.8 × as long as first tergite, shorter than metasoma, 0.9 × as long as hind femur.

Colour. Head, mesosoma and antenna dark brown. Mandible, metasoma, legs and pterostigma brown. Wings hyaline.

Male. Unknown.

Comparative diagnosis. This species is similar to D. teutonianse Peris-Felipo, 2016 , but differs from it in having the eye in lateral view 1.9 × as wide as temple medially (1.5 × in D. teutoniaense ), face 1.7 × as wide as high (1.2 × in D. teutoniaense ), mandible 1.5 × as long as its maximum width (2.0 × in D. teutoniaense ), first flagellar segment 3.5 × as long as its maximum width (5.5 × in D. teutoniaense ), hind femur 4.2 × as long as its maximum width (5.0 × in D. teutoniaense ), and the first metasomal tergite 3.9 × as long as its apical width (2.8 × in D. teutoniaense ).
