Holotype information. Type locality: Vietnam: Sonla Province , Song Ma. Deposited at Zoological Institute, Russian Academy of Sciences, St. Petersburg, Russia (not examined).

Materials examined. China: 2 males, Yunnan, Mengla, Longmen , 17-v-2009, Libin Ma coll. ; 4 males, Yunnan, Mengla, Yaoqu , 9-vi-2013, Libin Ma coll. ; 4 females, Yunnan, Mengla, Longmen , 17-v-2009, Libin Ma coll ..

Description. Male. Body small to medium for the genus. Head small. Occiput pubescent and somewhat broad. Ocelli small and median ocellus semilunar. Antennal scape round and shield-like. Genae slightly convex. Labrum straight apically. Terminal maxillary palpus elongate and rounded distally, longer than 3rd palpus. Terminal labial palpus rod-like, conspicuously longer than total length of remaining palpi. Pronotal disc flattened and slightly trapezoidal, nearly in equal width of apical and basal margins.Anterior margin of pronotum straight or slightly concave, posterior margin convex. Forewing somewhat narrowed dorsally. Harp area bearing 4–5 harp veins. False veins distributed in harp field, chordal field and mirror. Apical field short and possessing 6 branches (sometimes numbered 7) ( Fig. 4A View FIGURE 4 ). Hind wings short and slightly exceeding apical field. External tympanum shaped as long ovoid. Hind tarsus armed with two rows of small spines dorsally, inner numbering 7–8 and outer spines numbering 8–9.

Metanotal gland armed with transverse and sinuate convexity anteriorly, shallow and U-like concavity medially ( Fig. 4C View FIGURE 4 ). Anal plate tongue-shaped, half of basal sides ridged and apex margin almost straight ( Fig. 4D View FIGURE 4 ).

Male genitalia ( Figs. 4 View FIGURE 4 E–4G). Dorsal lobe of basal epiphallus bisinuate, bearing thick and distally expanded lateral process; median process conspicuously longer than width, usually possessing deep concavity distally ( Fig. 4E View FIGURE 4 ). Lateral edges of epiphallus paralleled and narrowed between them ( Fig. 4F View FIGURE 4 ). In lateral view, epiphallic apex expanded with rounded distal margin and armed with denticles at bottom ( Fig. 4F View FIGURE 4 ); in dorsal view, epiphallic apex possessing straight inner margin and outside margin somewhat concave ( Fig. 4E View FIGURE 4 ).

Female. Similar to male ( Fig. 4B View FIGURE 4 ). Ovipositor very much longer than hind tibia; its apex of rather acute and episternites blunt ( Figs. 13E View FIGURE 13 , 14E View FIGURE 14 ).

Coloration. Head dorsum colored dark and face colored light. Pronotum colored dark brown, except bladeshape pattern ( Fig. 4A View FIGURE 4 ). Subgenital plate ornamented with yellow triangular spot ventrally.

Measurements. Male (n=6). BL 15.56±2.62, HW 2.54± 0.44, PL 2.14±0.42, PW 3.82±0.39, FWL 14.62±1.66, HWL 5.13±0.41, DVL 3.46±0.33, ML 3.26±0.31, HFL 8.86±0.24, HTL 6.58±0.32, HML 3.87±0.29. Female (n=4). BL 15.35±2.02, HW 3.32±0.51, PL 2.14±0.23, PW 3.97±0.44, FWL 14.49±1.88, HFL 9.06±1.20, HTL 5.74±0.99, HML 3.36±0.60, OL 9.96±0.95.

Remarks. This species is very similar to I. (I.) vietnamensis in structure of male genitalia, but the epiphallic apex is rounded.
