Head and mesonotum, dorsal view. Mesosoma . In lateral view 1.2 × as long as high. Mesoscutum (in dorsal view) 1.1 × 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 lateral carinae. Precoxal sulcus present, crenulated, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow crenulated. Propodeum completely sculptured with median longitudinal carinae. Propodeal spiracles small, its diameter 0.2 × as wide as distance from spiracle to anterior margin of propodeum. FIGURE 43.

Fore and hind wings. Leg . Hind femur 3.6 × as long as its maximum width. Wings . Radial (marginal) cell 3.8 × as long as its maximum width. Vein r2 (3-SR) 2.0 × 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, weakly striated in apical half. Ovipositor 0.8 × as long as first tergite, shorter than metasoma, 0.6 × as long as hind femur. Colour . Body and antenna dark brown. Legs and first metasomal tergite yellowish brown. Wings hyaline. Male. Unknown. Comparative diagnosis. This species is similar to D. multiareolatum Peris-Felipo 2016 ; differences between both species are shown after the redescription of the latter species.
