Antenna with 26-28 ( HT : 28) flagEllomErEs. Mesosoma. Pronotum largely smooth except for postErior margiN. ScutEllum flat, dENsEly puNctatE ( Fig. 3 ). MEsoscutum dENsEly puNctatE, with fiNE, short traNsvErsE striae medially ( Fig. 3 ). Mesopleuron with longitudinal striae before smooth speculum ( Fig. 4 ). Propodeum covered with fine transverse striae anteriorly, with rather coarse striae posteriorly, without carinae except for pleural carina and part of posterior transverse carina ( Fig. 5 ). Pleural carina distinctly concave at area near spiracle ( Fig. 5 ). Fore wing 6.3–8.0 ( HT : 8.0) mm. Vein cu-a of fore wing slightly reclivous to slightly inclivous, its anterior end opposite to ( Fig. 1 ) or slightly based from posterior end of vein Rs+M. Vein Rs+2r of fore wing more or less sinuate ( Fig. 1 ). Vein 1-cu of hind wing longer than vein cu-a of hind wing ( Fig. 1 ). Inner aspect of fore tibia with 4–6 distinct large setae. Hind femur 5.5–6.2 ( HT : 6.0) times as long as maximum depth in lateral view. Metasoma. T 1 2.0–2.6 times as long as maximum width, densely punctate ( Fig. 7 ), slightly transversely striated medially. T 2 and anterior 0.3 of T 3 densely punctate ( Fig. 7 ). Posterior 0.7 of T 3, T 4- T 7 finely sculptured ( Fig. 7 ). Ovipositor sheath 0.6 times as long as fore wing and 1.2–1.3 ( HT : 1.2) times as long as hind tibia. Colouration ( Figs. 1–7 ). Head black to blackish-brown, except for: inner orbit, outer surface of base of antenna, dorsal surface of F9 to base of F14, and palpi white; clypeus reddish-brown. Mesosoma black to blackish-brown, except for: anterior margin of pronotum usually tinged with reddish-brown. Wings hyaline, with blackish-brown veins. Legs black to blackish-brown except for: fore trochantellus, base of hind tibia, apical 0.1–0.5 ( HT : 0.5) of hind TS1 and TS2-TS4 white; fore and mid tibiae, femora, tarsi more or less tinged with whitish-brown; base and apex of hind femur narrowly tinged with yellowish-brown. Metasoma black to blackish-brown, except for: posterior margin of T 1- T 4 narrowly tinged with reddish-brown to yellowish-brown; membranous part of sternites white; ovipositor yellowish-brown to reddish-brown. Male. Unknown. Distribution. Japan (Honshu and Shikoku). Etymology. The specific name is from the short ovipositor. Remarks. This species resembles D. orientalis in having the black hind coxa and femur, but can easily be distinguished from them by the black fore and mid coxae and the short ovipositor (see the following key).
