Description. Male. Body size medium for the genus. Head small. Occiput somewhat broad. Ocelli small, median ocellus ovoid and lateral ones expanded. Antennal scape rounded and shield like, nearly as wide as rostrum. Labrum apical margin almost straight. Terminal maxillary palpus truncated, longer than 3rd palpus. Terminal labial palpus rod-like and apex truncated, almost equal to total length of remaining palpi. Pronotal disc trapezoidal, depressed around median groove and armed with apical and basal margins straight ( Fig. 5A ). Harp area with 5 (sometimes 4) oblique veins. False veins positioned in harp field and mirror. Apical field of elytra short, equal or slightly longer than width and armed with 7 branches ( Fig. 5A ). Hind wings elongate, visible portion almost as long as apical field. External tympanum slightly smaller and ovoid. Hind tarsus armed with short dorsal spines (inner and outer numbered 6:7).

Metanotal gland armed with transverse and sinuate convexity anteriorly, shallow and U-like concavity medially ( Fig. 5C ). Anal plate tongue-shaped, half of basal sides ridged and apically rounded ( Fig. 5D ).

Male genitalia ( Figs. 5 E–5G). Dorsal lobe of basal epiphallus bisinuate, lateral process somewhat evenly thickened and median process short ( Fig. 5E ). Lateral edges of epiphallus expanded from middle to apex. In lateral view, epiphallic apex somewhat extended upward, slightly squared apically and armed with denticles dorsally ( Fig. 5F ); in dorsal view, epiphallic apex armed with straight inner margin and outer margin widely concave ( Fig. 5E ).

Female. Similar to male ( Fig. 5B ). Ovipositor very longer than hind tibia, almost two times longer than the latter; its apex and episternites both slightly blunt ( Figs. 13A , 14A ).

Coloration. Body color light brown. Head colored dark. Pronotal disc color light brown, but proximally dark and ornamented with dark fan-shaped patterns medially.

Measurements. Male (n=7). BL 17.85±1.88, HW 2.81±0.37, PL 2.03±0.33, PW 3.53±0.45, FWL 14.71±1.06, HWL 3.94±0.34, DVL 3.74±0.26, ML 3.40±0.45, HFL 8.07±0.87, HTL 5.43±0.71, HML 4.03±0.28. Female (n=2). BL 16.85±1.20, HW 2.99±0.32, PL 1.91±0.22, PW 3.73, FWL 13.80, HWL 5.43, HFL 7.78±0.86, HTL 5.56±0.54, HML 4.15±0.40, OL 10.42±0.68.

Remarks. This species is very similar to I. (I.) aperta and I. (I.) vietnamensis in both body features and genitalia, but its epiphallic apex acute and curved upward in lateral view.
