Type material.
Holotype. ♂ (#04172), CHINA: Mengyuan Substation, Mengla Station, Xishuangbanna National Nature Reserve, Guanlei, Mengla, Xishuangbanna, Yunnan, 14-15.xi.2012, JJ Gao (KIZ).
Paratypes: same data as holotype (5♂, 2♀: #04171, #04173-4178, KIZ, SEHU).
Diagnosis.
Wing largely clouded, except for central pale patch around dm-cu vein and periphery (Fig. 3J View Figure 3 ); dorsolateral tentorial apodemes slightly divergent in basal half (Fig. 4M View Figure 4 ); tenth sternite nearly flat (Fig. 7E View Figure 7 ); oviscapt valve half as broad as long (Fig. 7J View Figure 7 ).
Description.
Head (Figs 3H, I View Figure 3 , 4K-O View Figure 4 ): First flagellomere grayish yellow. Supercervical setae 17-18 per side; postocular setae 20-22 per side. Palpus with one subprominent lateromedial seta. Cibarium with 77-79 medial and ca. 10 posterior sensilla per side.
Wings (Fig. 3J View Figure 3 ): Veins pale brown to dark brown, but pale within central pale patch. Halter pale gray; stem darker.
Legs (Fig. 3H View Figure 3 ) pale grayish yellow; foreleg tibia and tarsus, mid-leg femur and distal portion of hindleg femur darker. Hindleg tibia lacking apical seta. Mid-leg first tarsomere longer than total length of four succeeding tarsomeres; hindleg first tarsomere as long as total length of four succeeding tarsomeres.
Male terminalia (Fig. 7A-I View Figure 7 ): Epandrium pubescent except for anterior portion, with ca. three dorsal and 10-11 ventral, long setae per side. Surstylus with prensisetae in slightly concave row on caudal margin, 2-3 apically pointed spines but no pubescence on outer surface and ca. 16 apically pointed, recurved spines on inner, caudal portion. Cercus pubescent except for caudal margin, with 10-13 long setae near dorsal to posterior margin and 8-10 short setae in cluster on ventral portion of sclerotized marginal plate. Paramere with sensilla subapically.
Female terminalia (Fig. 7J-L View Figure 7 ): Oviscapt valve with ca. four lateral and 12-13 marginal, peg-like ovisensilla. Introvert of spermathecal capsule 1/4 as deep as capsule height.
