Diagnosis. This species can be distinguished from other Diplonevra species by the combination of the following characteristics: inner face of male hind trochanter with four long, sinuate setae arranged in longitudinal row on median area, and 2–4 shorter, pointed setae on ventral margin; ventrobasal area of inner face of male hind femur with long ascending process bearing two robust, blunt setae (upper one short, peg-like, while lower one long, spatulate) at tip; hind tibia with two dorsal longitudinal setal palisades and 2 or 3 anteroventral short setae; hypopygium nearly globose.

Description. Male. Body length 2.22–2.87mm (n=7). Head ( Fig. 1K View FIGURE 1 ). Frons blackish to dark brown, shiny. Flagellomere 1 yellowish brown, as large as one-third of compound eye, subglobose, slightly pointed apically. Arista yellowish brown. Palpus yellowish brown, as wide as maximum width of flagellomere 1, with 6 or 7 bristles (mostly 6) apically and some short hairs ventrally. Labrum and labella pale yellow. Thorax ( Fig. 1L View FIGURE 1 ). Scutum and scutellum blackish to dark brown. Posterior margin of scutum with 1 or 2 pairs of long prescutellar bristles (mostly one pair, outermost pair always present). Scutellum with two pairs of long bristles of subequal length; anterior scutellar bristles convergent; posterior scutellar bristles convergent and sometimes apically crossing each other. Pleuron ( Fig. 1K View FIGURE 1 ) brown. Legs ( Fig. 1K View FIGURE 1 ) brown to dark brown except fore, mid-tibiae and tarsi yellowish brown. Fore tibia with single strong dorsal seta on basal half and one row of dorsal short setulae on apical half. Midtibia ( Fig. 4J View FIGURE 4 ) with two dorsal longitudinal setal palisades; anterodorsal one extending two-thirds of midtibial length while posterodorsal one extending entire length of midtibia. Two dorsal midtibial bristles on basal half protruding at different point each; anterodorsal one at basal one-fifth, posterodorsal one at basal one-ninth of midtibia. Inner face of hind trochanter ( Fig. 6H, I View FIGURE 6 ) with four long, sinuate setae arranged in longitudinal row on median area, and 2–4 shorter, pointed setae on ventral margin. Ventrobasal area of inner face of hind femur ( Fig. 6H, I View FIGURE 6 ) with long ascending process; anterior margin lamellar, apex with two robust, blunt setae (upper one short, peg-like, while lower one long, spatulate) protruding perpendicularly. Hind tibia ( Fig. 4K, L View FIGURE 4 ) with two dorsal longitudinal setal palisades, 2 or 3 anteroventral short setae, and one row of posterodorsal fine setae. Wing ( Fig. 5F View FIGURE 5 ). 1.62–2.26mm long (n=7). Costal index 0.45–0.47. Mean costal ratio 6.4:1.0:1; range 5.3–7.0:1.0–1.1:1. Costal setae of costal section III 0.03–0.05mm long. Vein of costal sections II–III slightly thickened. Base of Rs with single short hair. Vein M 1 slightly curved, weakly recurved apically. Vein brown and membrane hyaline with pale brown tinge. 3–5 (mostly 4) alular setae present, 0.08–0.14mm long. Halter dark brown. Abdomen ( Fig. 1K, L View FIGURE 1 ). Tergites dark brown. Venter of abdomen grayish brown. Hypopygium ( Fig. 8G, H View FIGURE 8 ) nearly globose, dark brown but epandrium brighter, shiny. Epandrium bare dorsally. Left side of epandrium ( Fig. 8G View FIGURE 8 ) with finger-shaped epandrial lobe, bearing some hairs and one long apical seta. Right side of epandrium ( Fig. 8H View FIGURE 8 ) extended posteroventrally, with several long, fine hairs on posterior margin and minute, hooked lobe curved inward on posteroventral corner. Hypandrium tomentose. Left plate of hypandrium ( Fig. 8G View FIGURE 8 ) with rounded posterior margin. Right plate of hypandrium ( Fig. 8H View FIGURE 8 ) with curved posterior margin. Cercus with one pair of pale yellow sclerites mounted dorsally on brown stalk; length of cercus about four times as long as maximum width of cercus; stalk with numerous hairs of similar length on surface.

Ecology. Ecological information for the species is largely unknown.

Remarks. Diplonvera lamella Liu & Yang (2016) is considered a junior synonym of D. hirsuta on the basis of the hind leg character and hypopygium.

Distribution. Korea (new record, Gyeonggi-do, Gangwon-do, Jeollabuk-do), Russia (Far East), China.
