Description. Male. Body average size for the genus. Head small. Occiput pubescent and somewhat broad. Median ocellus small, ovoid and lateral ones extended. Antennal scape rounded shield-like. Labrum straight apically. Terminal maxillary palpus and labial palpus rod-like; terminal maxillary palpus longer than third palpus; terminal labial palpus longer than total length of remaining palpi. Pronotal disc flattened and trapezoid; anterior margin somewhat concave, posterior margin almost straight ( Fig. 7A View FIGURE 7 ). Harp area bearing 4–5 veins. False veins distributed in harp field and mirror. Forewing broad and apically rounded ( Fig. 7A View FIGURE 7 ). Apical field slightly shorter and nearly equal to width of forewing and armed with 7 branches (sometimes 6 or 8) ( Fig. 7A View FIGURE 7 ). Visible part of hind wings longer than hind tarsus.

Metanotal gland armed with transverse and sinuate convexity anteriorly, shallow concavity medially and posterior part armed with a rather large convexity ( Fig. 7C View FIGURE 7 ). Anal plate rather short and tongue-shaped, bearing a shallow groove medially and rounded lateral edges ( Fig. 7D View FIGURE 7 ).

Male genitalia ( Figs. 7 View FIGURE 7 E–7G). Dorsal lobe of basal epiphallus bisinuate; lateral process somewhat thickened and expanded apically; median process transversely widened, bisinuate and bearing deeply and widely concave distally ( Fig. 7E View FIGURE 7 ). Lateral margins of epiphallus almost paralleled and broadly separated ( Fig. 7F View FIGURE 7 ). In lateral view, epiphallic apex somewhat expanded, armed with two large denticles and without small denticles ( Fig. 7F View FIGURE 7 ); in dorsal view, epiphallic apex with both arched and concave margins inside and outside ( Fig. 7E View FIGURE 7 ).

Female. Body slightly smaller than male ( Fig. 7B View FIGURE 7 ). Ovipositor very longer than hind tibia; its apex rather acute and episternites blunt ( Figs. 13F View FIGURE 13 , 14F View FIGURE 14 ).

Coloration. Head colored dark dorsally with lighter frons and clypeus.

Measurements. Male. BL 19.32, HW 3.06, PL 2.46, PW 4.34, FWL 15.27, HWL 5.06, 4.26. Female. BL 19.02, HW 3.02, PL 2.12, PW 3.78, FWL 14.93, HFL 10.00, HTL 7.43, HML 4.51, OL 10.24.

Remarks. This species is similar to I. (I.) vietnamensis and I. (I.) aperta , but the epiphallic apex possesses two large teeth at bottom and lacking other small denticles.
