In dorsal view, 2.0 × as wide as median length, 1.6 × as wide as mesoscutum, smooth. Eye in lateral view as wide as temple medially. POL 0.9 × OD; OOL 2.4 × OD. Face 2.3 × as wide as high. Clypeus 2.5 × as wide as high. Paraclypeal fovea short, not 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 long, pointed apically; lower tooth, subrounded. Аntenna 19-segmented. First flagellar segment 3.3 × as long as its apical width. Second flagellar segment 2.6 times; third to 16th segments 2.1 × as long as their maximum width, and 17th (apical) segment 3.6 × as long as wide respectively. Mesosoma . In lateral view 1.1 × as long as high. Mesoscutum (in dorsal view) about 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 mainly smooth with complete median longitudinal carinae and with 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 4.5 × as long as its maximum width. Wings . Radial (marginal) cell 3.6 × 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, 2.1 × as long as its apical width, smooth. Colour . Body brown. First metasomal tergite, mandible, antenna, legs and pterostigma yellowish brown. Wings hyaline. Female. Unknown. FIGURE 14. Dinotrema ephemera (Viereck, 1917) (male, holotype). A . Propodeum and first metasomal tergite, dorsal view. B. Fore wing. Comparative diagnosis. This species is similar to D. saileri (Fischer, 1969) and D. teutonianse Peris-Felipo, 2016 . Dinotrema ephemera differs from D. saileri having the propodeum mainly or widely smooth and with complete median longitudinal carina (completely sculptured in D. saileri ), face 2.3 × as wide as high (1.9 × in D. saileri ), clypeus 2.5 × as wide as high (3.3 × in D. saileri ), mandible 1.3 × as long as its maximum width (1.0 × in D. saileri ), precoxal sulcus not reaching anterior and posterior margins of mesopleuron (reaching anterior margin in D. saileri ), diameter of propodeal spiracle 0.3 × as wide as distance from spiracle to anterior margin of propodeum (0.6 × in D. saileri ), hind femur 4.5 × as long as its maximum width (4.1 × in D. saileri ), and the first metasomal tergite 2.1 × as long as its apical width (1.5 × in D. saileri ). Finally, this species differs from D. teutoniaense having the eye in lateral view as wide as temple medially (1.5 × in D. teutoniaense ), face 2.3 × as wide as high (1.2 × in D. teutoniaense ), clypeus 2.5 × as wide as high (3.1 × in D. teutoniaense ), mandible 1.3 × as long as its maximum width (2.0 × in D. teutoniaense ), the first flagellar segment 3.3 × as long as its maximum width (5.5 × in D. teutoniaense ), hind femur 4.5 × as long as its maximum width (5.0 × in D. teutoniaense ), and the first metasomal tergite 2.1 × as long as its apical width (2.8 × in D. teutoniaense ).
