Figs. 1–2
Material examined. Holotype: female, Shaanxi, Niubeiliang Guanghuojie, 26.VII.2014, Mao Juan, No 202019707 (ZJUH).
Description. Female (Fig. 1) holotype. Body length 5.2 mm, fore wing length 3.6 mm.
Head. Antenna with 29 flagellomeres; first flagellomere ca. 1.4× longer than wide. Face (Fig. 2E) granulose. Clypeus (Fig. 2E) granulose with small punctures, apical margin of clypeus widely arched, blunt. Malar space granulose, ca. 0.5× basal width of mandible. Upper tooth of mandible slightly larger than lower tooth, with a lamella. Frons (Fig. 2E) granulose and without median carina. Vertex (Fig. 2F) granulose. Interocellar region (Fig. 2F) granulose. Interocellar distance 1.5× ocello-ocular distance and 2.2× distance between median and lateral ocelli; distance between lateral ocelli and eyes ca. 1.0 × as long as diameter of ocellus. Temple mat, ca. 0.5× as long as eyes in lateral view. Occipital carina evenly arched, reaching hypostomal carina before mandible base.
Mesosoma. Pronotum granulose, transversely striate extreme-ventrally. Mesoscutum (Fig. 2G), scutellum and metanotum granulose. Mesopleuron (Fig. 2B) granulose, very weakly transversely striate below tegula. Metapleuron (Fig. 2B) granulose. Propodeum (Fig. 2C) granulose; area basalis triangular; area superomedia separate from area petiolaris; costula absent; other carinae all strongly developed; propodeal spiracle nearly round.
Wing. Fore wing (Fig. 2A) areolet present emitting vein 2m-cu from its apical half, with a moderate stalk. Marginal cell short, distal part of surrounding vein 2.0× longer than proximal one. Vein 1cu-a distad of M& RS by 0.3 of its length. External angles of second discal cell acute (75°). Hind wing with CU&cu-a inclivous, intercepted at lower 0.2.
Legs. Hind femur 4.2× longer than wide. First tarsal segment without ventral row of setae medially. Tarsal claws weakly pectinate basally.
Metasoma. First metasomal segment (Fig. 2H) with glymma located at basal 0.3. First tergite 2.3× longer than width of postpetiole. Postpetiole granulose. Second tergite 0.6× as long as first tergite, 0.8× its apical width; thyridium circular and close to base of second tergite. Third tergite 0.6× longer than its apical width. Sixth and seventh tergites without medial emargination. Ovipositor (Fig. 2D) straight, ca. 2.0× longer than apical depth of metasoma, with a nodus before apical notch.
Colour. Black. Mandible except teeth and tegula, yellow, scape and pedicel brown; fore and mid coxae apically, trochanters and trochantelli pale whitish, remainder of fore leg yellowish brown with tarsomeres darker; hind coxa black, femur yellowish brown, tibia medially pale yellow, tibia basally and apically infuscated, tarsomere blackish brown; metasoma wholly black.
Comparison. This species is similar to D. pedella (Holmgren, 1860), but differs from the latter by having a nodus before apical notch of ovipositor, propodeal costula absent and hind tibia infuscated basally and apically.
Etymology. Name derived from “granosus” (Latin for “granular”), because of its largely granulose body sculpture.
