Pronotum ~ 1.43-1.60 x as width across humeral angles as its median length; scutellum ~ 0.96-1.16 x as long as its width. Anterior peritreme of metathoracic scent gland slightly larger than protruding posterior peritreme, gyrification of evaporatorium deep (Fig. 4C, D ). Pregenital abdomen . Abdomen oblong, spiracles situated near lateral margin of abdominal sterna III-VII (segments III to VIII in female), before middle line of each segment; sternum VII of male strongly concave medially, length of concave part ~ 1/2 length of sternum VIII in ventral view; in female plica triangular, and partly exposed out of sternum VI, posterior margin of sternum VII sinuated. External male genitalia . Genital capsule opening dorsally (Fig. 4E, F ), dorsoposterior rim wide, median projection conspicuous, triangular (Fig. 5D : mdp), posterior margin of genital capsule broadly sinuate and ventroposterior process median (Fig. 5D : mvp), lateral portion of posterior margin roundly produced on each side (Fig. 5D ); dorsal margin of base of paramere near straight, ventral region of base of paramere with triangular lobe (Fig. 5E-G ), distal portion sickle-shaped (Fig. 5E-G ); phallus with a sclerotized articulatory apparatus (Fig. 5A-C ), phallotheca barrel-shaped, unarmed (Fig. 5A-C : phth), conjunctiva rigid and complex, with one pair of membranous processes and a pair of slender, triangular adjacent ventral conjunctival sclerites (Fig. 5B, C : vcs), aedeagus coiled, strongly sclerotized, distal portion tubular, obliquely truncate apically (Fig. 5A-C : aed). External female genitalia . Laterotergite VIII subtriangular, with sinuate inner margin, spiracles nearer to basal margin than to lateral margin; laterotergites IX subtriangular, posterior portion of inner margin concave (Figs 6C , 14D ). Valvifers VIII nearly triangular, posterior portion of outer margin slightly convex (Fig. 6C : vf8); posterior distal portions of valvulae VIII with dense hair-like setae (Fig. 6C : va8); valvifers IX slightly sclerotized (Fig. 6A : vf9); distal portions of valvulae IX strongly sclerotized, sheath-like, downcurved (Fig. 6A : va9); ring sclerite of gynatrium large, slender and curved (Fig. 6A : rs); spermatheca with a conspicuous ampulla subapically, distal area of ampulla expanded, body of ampulla elongate (Fig. 6B, D : am); distal region with relatively long flexible zone (Fig. 6B, D : fz), with sclerotized, tightly tangled coiled duct (Fig. 6B, D : cd), and not distinctly sclerotized seminal receptacle globose (Fig. 6B, D : sr).
