Fore leg brown on apex of femur and dark yellow on anteroapical part of tibia in female, yellow on anteroapical part of femur and anterior part of tibia in male.

Interocellar furrow and lateral ridge of frontal area distinct respectively ( Fig. 12A View FIGURE 12 ). Distance between eyes at anterior tentorial pit 1.1–1.2 × eye height. Antenna gradually tapering ( Fig. 13A, B View FIGURE 13 ), with length 2.4 × head width in female, 3.2 × in male. In female antenna, flagellum not compressed, with setae slanted toward apex of antenna and as long as or somewhat shorter than middle width of flagellomere 1 in dorsal view; middle and basal flagellomeres slightly bulging at apices ( Fig. 13A View FIGURE 13 ); flagellomere 1 with dorsal length 0.63 × eye height, 3.4 × apical breadth in lateral view; flagellomere 2 dorsal length 1.2 × flagellomere 1 dorsal length; flagellomere 7 with length 6.4 × breadth in lateral view. In male antenna, flagellum compressed from both sides; setae, except for dorsal setae, very long and about as long as 1.5 × middle width of flagellomere 1 in dorsal view ( Fig. 8F View FIGURE 8 ); dorsal setae slanted toward apex of antenna, and setae on other sides almost erect; flagellomeres except for apical one bulging at apices ( Fig. 13B View FIGURE 13 ); flagellomere 1 with dorsal length 0.82 × eye height, 3.3 × apical breadth in lateral view; flagellomere 2 dorsal length 1.2 × flagellomere 1 dorsal length; flagellomere 7 with length 7.5 × breadth in lateral view.

Mesoscutum, mesoscutellum and metascutellum densely covered with setae. Epicnemium entirely glabrous, with epicnemial groove distinct except for short posterior part. Mesepisternum broadly glabrous ventrolaterally.Anepimeron without membranous part. Furrow dividing katepimeron into anterior and posterior parts rather deep but vague; setae present only on posterior raised margin. Hind tarsus with length of plantar lobe of tarsomere 1 about 0.7 × distance between plantar lobes of tarsomeres 1 and 2 in female, about 0.4 × in male. Tarsal claws with inner tooth large, shorter than apical tooth ( Fig. 13D View FIGURE 13 ); distance between apices of apical and inner teeth shorter than depth of concavity between these teeth. In fore wing, proximal part of vein 2A+3A bifurcate, with anterior branch short or long and separated from vein 1A; cell 2Rs much longer than cells 1R1 and 1Rs combined in posterior length ( Fig. 13A, B View FIGURE 13 ); junction of vein Rs and crossvein 2r-rs markedly proximally distant from junction of vein Rs and crossvein3r-m.

Dorsum of abdomen mostly mat and distinctly microsculptured in both sexes ( Fig. 12C, D View FIGURE 12 ). In female, ovipositor sheath 0.85 × hind tibia in length (equal in holotype, Wei 2002); valvula 3 slightly extending beyond tergum 10 posteriorly, with apex narrowly rounded, dorsal edge very slightly convex, and ventral edge roundly convex and posteriorly straight ( Fig. 13E View FIGURE 13 ). Ovipositor broad ( Fig. 13F View FIGURE 13 ). Lance with first (most basal) suture slightly curved and diverging from second suture dorsally; other sutures straight. Lancet almost straight, with dorsal edge slightly concave near apical third, with 19 annuli ( Fig. 13G, I View FIGURE 13 ) (17–18 annuli in holotype, Wei 2002); first and second ctenidia each being short dorsal band; third and fourth ctenidia divided into dorsal and ventral bands; apical ctenidia dorsally separated from olistheter ( Fig. 13I View FIGURE 13 ); serrulae, except for some basal and apical ones, each anteriorly with tubercle ( Figs 11G View FIGURE 11 , 13H, I View FIGURE 13 ); middle serrulae (fifth to eighth serrulae from base or 12th to 15th from apex) each with 20–26 denticles ( Fig. 11G View FIGURE 11 ); apical eight serrulae flat ( Fig. 13I View FIGURE 13 ); apical 10 serrulae with denticles lining up without gaps; marginal sensilla pore-shaped or nearly so, and far from serrulae ( Figs 11G View FIGURE 11 , 13H View FIGURE 13 ; fig. 4c, d in Wei 2002), except those of apical annuli very short funnel-shaped and located near serrulae ( Fig. 13I View FIGURE 13 ). Male genitalia ( Figs 11D View FIGURE 11 , 13J, K View FIGURE 13 ) with parapenis extremely deformed, divided into lateral and basal sclerites (for these sclerites, see also Fig. 2N View FIGURE 2 ), without setae; lateral sclerite located laterally to penis valve; basal sclerite apically completely fused with opposite basal sclerite and forming markedly projecting and truncate apex; basal ring basally connecting with basal sclerite of parapenis and apically rounded; digitus of volsella shorter than harpe. In penis valve, valviceps much shorter than valvura, with dorsal edge markedly convex in apical two thirds and ventral edge straight ( Fig. 13L View FIGURE 13 ).

Material examined. This species was described based on only one female ( holotype) from China ( Henan) ( Wei 2002). We have not examined the holotype .
