description: Genus Qinlingea gen. nov.
Type species: Isopsera brachystylata Liu & Wang, 1998
Diagnosis: Fastigium verticis slightly narrower than first segment of antenna. Surface of disc in prozona smooth, without lateral carina. Anterior coxae armed; with open tympanum on both sides. Each femur with one ventral spine and one dorsal spine on the genicular lobe. Tegmen widened in middle, with radical sector bifurcated. Male subgenital plate with robust styli. Ovipositor with margins somewhat crenulate.
Description: Head ovoid, occiput convex and smooth (Figs. 31, 33); fastigium verticis (Fig. 32) dorsally sulcate, obtuse, slightly deflexed, not touching fastigium frontis; fastigium frontis inversely triangular, apex obtuse (Fig. 31). Compound eye semi-spherical, greatly bulging, venral margin less extending beyond ventral margin of antennal scrobe (Fig. 33). Antenna silk-like, long. Pronotum slightly constricted anteriorly (Fig. 35); anterior margin slightly concave in middle, posterior margin wide, obtuse (Fig.35); disc in prozona smooth, and that in metazona flat (Fig. 35); lateral lobe of pronotum approximately slightly higher than long; humeral sinus distinct (Fig. 34). Anterior tibiae dorsally sulcate, widened at and gradually constricted below tympana. Anterior and median femora provided with spines on ventro-anterior margin; posterior femur with spines on both ventral margins. Anterior tibiae without dorsal spines except with one dorsal exterior apical spine; median tibiae with dorso-internal spines; posterior tibiae with dorsal spines on both sides. Tegmen translucent, with irregular veinlets. Costa indistinct; subcostal vein and radial vein joined at base, then separated but closely abutted together till before apical part of tegmen. Apex of tegmen rounded. Male tenth abdominal tergum normal; apical margin truncate. Female tenth abdominal tergum normal; apical margin slightly concave in middle. Female epiproct equilateral triangular; apex rounded.
Discussion: Isopsera brachystylata Liu & Wang, 1998 was distinguished from other species of Isopsera by smooth disc of pronotum without distinct lateral carinae (Figs. 34–35), tegmen distinctly widened (Fig. 37), and male subgenital plate with much shorter styli (Figs. 36, 39). All above characters separate I. brachystylata from the genus Isopsera. In this study, we designate I. brachystylata the type species of Qinlingea.
The new genus is distinguished from genera of the tribe Phaneropterini and Ducetiini by male subgenital plate possessing distinct styli. It is distinct from genera of Ducetiini by the pronotum having a distinct humeral sinus and the male stridulatory area not haveing secondary cross veinlets. It differs from Isopsera in the pronotum being without lateral carinae, the tegmina being rather wide, and the male subgenital plate having rather short styli. This genus resembles Ruidocollaris in the characteristics of leg spination, structures of the male abdominal apex and the male stridulatory area, but differs by the shape of tegmina and the tympanal organs.
Distribution: China.
