Material examined. 1 male ( holotype ), " U.S.А. , Cabin John, Md. , v. 1917 , R.M. Fouts Collector " ( NMNH ). Redescription. Male. Body 1.6 mm ; fore wing 2.4 mm ; hind wing 1.5 mm . Head. In dorsal view, 1.8 × as wide as median length, 1.4 × as wide as mesoscutum, smooth. Eye in lateral view 1.3 × as wide as temple medially. POL 1.0 × OD; OOL 2.5 × OD. Face 2.6 × as wide as high. Clypeus 2.6 × 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 wide, as long as lower tooth; middle tooth pointed apically; lower tooth subrounded. Аntenna 23-segmented. First flagellar segment 3.0 × as long as its apical width. Second to eighth segments 2.4 × as long as their maximum width; ninth to 14th segments 2.3 ×; 15th and 17th segments 2.1 ×; 18th to 20th segments 2.3 ×, and 21st (apical) segment 2.7 × as long as its maximum width respectively. Mesosoma . In lateral view 1.2 × 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, crenulated, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum sculptured, with complete median longitudinal carinae and with subtransverse carinae emerging from median carina reaching propodeal edges. Propodeal spiracles small, its diameter 0.2 × as wide as distance from spiracle to anterior margin of propodeum. FIGURE 23. Dinotrema longibasis (Fischer, 1969) (male, holotype). A .

Metasoma . First tergite not widened towards apex, 2.5 × as long as its apical width, smooth. Colour . Body and antenna brown to dark brown. Mandible, scape, pedicel and legs yellowish brown. Wings hyaline. Female. Unknown. Comparative diagnosis. This species is similar to D. saileri (Fischer, 1969) , but differs from it in having the face 2.6 × as wide as high (1.9 × in D. saileri ), the first metasomal tergite 2.5 × as long as its apical width (1.5 × in D. saileri ), precoxal sulcus not reaching anterior margin of mesopleuron (reaching anterior margin in D. saileri ), posterior mesopleural furrow completely smooth (completely crenulated in D. saileri ), diameter of propodeal spiracle 0.2 × as wide as distance from spiracle to anterior margin of propodeum (0.6 × in D. saileri ), mandible 1.3 × as long as its maximum width (1.0 × in D. saileri ), paraclypeal fovea reaching halfway distance between clypeus and eye (not reaching halfway in D. saileri ), and eye in lateral view 1.3 × as wide as temple medially (1.0 × in D. saileri ).
