Aspilota clayensis Fischer 1969a: 103 ; Shenefelt 1974: 969; Marsh 1979: 220; Yu et al. 2012. Dinotrema clayensis: Peris-Felipo and Belokobylskij 2016b: 3 .

Material examined. 1 female (paratype), " U.S.А., Gold Head Branch, St. Pk., Clay Co., Fla., 19.i.1957, F.W. Mead, sta. 41" ( NHMW).

Redescription. Female. Body 1.9 mm; fore wing 2.1 mm; hind wing 1.2 mm.

Head. In dorsal view, 1.7 × as wide as median length, 1.6 × as wide as mesoscutum, smooth. Eye in lateral view 1.1 × as wide as temple medially. POL 1.1 × OD; OOL 3.8 × OD. Face 1.9 × as wide as high. Clypeus 2.5 × as wide as high. Paraclypeal fovea reaching halfway distance between clypeus and eye. Mandible 1.3 × as long as its maximum width, widened towards apex. Upper tooth rather wide, longer than lower tooth; middle tooth small, shorter than upper tooth, pointed apically; lower tooth short, subrounded. Аntenna more than 12-segmented (apical segments missing). First flagellar segment 3.2 × as long as its apical width. Second segments 2.2 × as long as its maximum width; third to tenth segments 2.0 × as long as their maximum width respectively.

Mesosoma. In lateral view 1.2 × 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-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 short subtransverse carinae emerging from median carina far distant from propodeal edges. Propodeal spiracles small, its diameter 0.2 × as wide as distance from spiracle to anterior margin of propodeum. Hind leg missing.

Wings. Radial (marginal) cell 3.8 × as long as its maximum width. Vein r2 (3-SR) 2.7 × as long as vein cuqu1 (2-SR); vein r3 (SR1) 2.1 × as long as vein r2 (3-SR).

Metasoma. First tergite weakly widened towards apex, 2.5 × as long as its apical width, smooth. Ovipositor 1.6 × as long as first tergite, shorter than metasoma.

Colour. Body, legs and pterostigma light brown to brown. Wings hyaline.

Male. Unknown.

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