Holotype. China: Male, Yunnan, Ruili, Zhenxi Botanical Garden , 1200 m, light trap, 27-vi-2007, Xiaochen Zhang coll. ( NWAFU).

Material examined. China: Male, Yunnan, Ruili, Zhenxi Botanical Garden , 14-vi-2013, Libin Ma coll ..

Description. Male. Body size small for the genus. Head small. Occiput pubescent, narrowed and convex. Median ocellus small and lateral ones expanded. Antennal scape somewhat rounded and wider than half width of rostrum. Labrum apical margin straight. Terminal maxillary palpus truncated, longer than 3rd palpus. Terminal labial palpus rod-like, longer than total length of remaining palpi. Pronotum not trapezoid, apical and basal margins nearly in same width, both margins almost straight ( Fig. 11A View FIGURE 11 ). False veins distributed in harp area and mirror.Apical external tympanum ovoid. Dorsal field of forewing somewhat broad ( Fig. 11A View FIGURE 11 ). Apical field developed and long, longer than width of mirror, armed with 8 branches ( Fig. 11A View FIGURE 11 ). Harp area bearing 5 harp veins. Exposed portion of hind wings nearly equal to length of hind tarsus ( Fig. 11A View FIGURE 11 ). Hind tarsus armed with 2 rows of small spines, inner spines numbering 7ā€“8; outer spines numbering 9ā€“11.

Metanotal gland armed with transverse sinuate convexity anteriorly, large and shallow convexity medially and almost flattened (except sides) posterior part ( Fig. 11B View FIGURE 11 ).

Male genitalia ( Figs. 11 View FIGURE 11 Cā€“11E). Dorsal lobe of basal epiphallus shaped as obtuse angle, lateral process slight in thickness and median process armed with straight apical margin ( Fig. 11C View FIGURE 11 ). Epiphallus somewhat rhomboid in dorsal view, expanded medially and constricted as acute angle distally ( Fig. 11C View FIGURE 11 ). Epiphallic apex is similar to I. (I.) basidentata in lateral view, but lateral lobes of ectoparamere extremely small, exposing inner paired processes ( Figs. 11D View FIGURE 11 ).

Coloration. Head colored dark. Pronotal disc colored dark medially and ornamented with blade-shaped patterns and lateral region colored light. Lateral lobes of pronotum colored dark. Legs primarily colored dark.

Measurements. Male. BL 17.86, HW 2.66, PL 1.74, PW 2.98, FWL 15.41, HWL 5.05, DVL 3.72, ML 3.36, HFL 8.44, HTL 5.69, HML 4.13.

Remarks. This species is similar to I. (I.) basidentata in that the epiphallic apex is curved upward, but its lateral lobes of the ectoparamere are very small and expose their inner parts. It is also similar to Itara (Gryllitara) curupi Gorochov, 2009 , but the epiphallus armed with proximal denticles and the ectoparamere lacks inner processes.
