Type material.

Holotype: ♂, China: Yunnan Province, Longling County (24°35'N, 98°41'E), 9-11 June 2011, Jian-Kun Long. Paratypes: 22♂♂25♀♀, same data as holotype, Yu-Jian Li, Zai-Hua Yang and Jian-Kun Long.

Description.

Body length: male 5.3-5.8 mm (N = 23), female 6.2-6.7 mm (N = 25).

Coloration. General color black (Fig. 3A-D ). Eyes brown, ocelli yellowish brown. Vertex black. Face generally blackish brown, carinae and margins brown. Rostrum brown. Pronotum dark to blackish brown, carinae paler; mesonotum black. Forewing semi-translucent, pale brown, stigma brown. Hind tibiae and abdominal sternites blackish brown.

Head and thorax. Vertex (Fig. 3A, C ) broad, 1.3 times wider than long; anterior margin arched convex; subapical transverse carina arc-shaped, connected with anterior border of vertex by two longitudinal small carinae; median carina absent; posterior margin nearly excavated at right angle. Frons (Fig. 3D ) 1.3 times as wide as long, with median carina distinct and fork of median carina near apex. Pronotum (Fig. 3C ) 1.3 times longer than vertex, posterior margin concaved in obtuse angle. Mesonotum 1.5 times longer than pronotum and vertex combined. Forewing (Fig. 3E ) 3.0 times longer than wide, with 10 apical and 5 subapical cells; fork Sc+RP slightly distad of fork CuA1+CuA2; first crossvein r-m basad of fork MP; RP 3 branches, MP with 4 terminals: MP 1, MP2, MP3, and MP4, fork MP1+MP2 distad of fork MP3+MP4. Hind tibia with 3 lateral spines; chaetotaxy of hind tarsi: 6/5, second segment of hind tarsus without platellae.

Male genitalia. Pygofer (Fig. 3F, G ) symmetrical, dorsal margin concave and U-shaped ventrally, widened towards apex; in lateral view, lateral lobes trapezoidally extended caudally. Medioventral process absent, replaced by two small projections. Anal segment (Fig. 3F, H, I ) asymmetrical, in lateral view, dorsal margin almost straight, ventral margin convex, right lobe larger than left one and apical lobe extended ventrally; 1.5 times longer than wide in dorsal view; anal style finger-like, beyond anal segment. Gonostyli (Fig. 3F, G, J ) symmetrical in ventral view; in inner lateral view, thumb-shaped, apical margin round, basal 1/3 with a deep round excavation and a tusk-like tooth. Aedeagus (Fig. 3K-N ) with total of seven processes. Base of periandrium with a scoop-like laminal process positioning slightly to right side of its ventral margin, directed cephalad. Endosoma convoluted with two sinuations, a right lateral one (Fig. 3K ) and a left lateral one (Fig. 3L ). In the right lateral view, endosoma with a long ribbon-like process, apex slightly expanded and round, curving left-dorsocaudally; basal portion of the ribbon-like process with two short laminal processes, apex acute, directed ventrocaudally. In left lateral view, the base of endosoma with a strongly curved process, apex acute, directed dorsocaudally; a long rod-like process arising from basal 1/3 of endosoma on the dorsal margin, curving downwards, apex round, directed dorsally, base of the long process with an extremely short spinose process, apex directed dorsocaudally.

Female genitalia. Pregenital sternite (Fig. 4A ) with caudal margin slightly convex in the middle, 2.3 times wider than long. Tergite IX (Fig. 4A, C ) moderately sclerotized, with a large nearly oval wax plate. Anal segment (Fig. 4B ) oval, 1.8 times longer than wide in dorsal view, anal style finger-like. Gonapophysis VIII (Fig. 4D ) reduced, apex acute. Gonapophysis IX (Fig. 4E ) comparatively short and thin. Gonoplac (Fig. 4F ) strap-shaped. Posterior vagina as shown in Fig. 4G, H . In ventral view, left side with a nearly rectangular sclerite, which with a pouch-like structure at the base and terminal; in dorsal view, basal area with an irregular large sclerite, which with a process basally.

Distribution.

China (Yunnan) (Fig. 5 ).

Etymology.

The species name is derived from Longling County, Yunan Province, where the type locality is located.

Remarks.

Male genitalia of I. longlingensis sp. nov. is similar to I. huapingensis Luo, Liu & Feng, 2019, but differs in: (1) left side of endosoma with a long rod-like process at basal 1/3, which with an extremely short spinose process basally (the latter in the same position with a foliaceous process, which without spinose process basally); (2) ventral margin of endosoma without process (in I. huapingensis , ventral margin of endosoma with a tusk-like process); (3) forewing with 10 apical cells (the latter with 9 apical cells).
