Figures 1 – 2 View FIGURE 1 View FIGURE 2
Description. Male. Body small. Head. Face ovoid, fastigium verticis conical, apex rounded, dorsal surface with 1 thin furrow ( Fig. 1A View FIGURE 1 ). Eyes nearly semiglobular, projecting outwards. Apical segments of maxillary palpi almost as long as subapical ones, apices faintly inflated ( Fig. 1B View FIGURE 1 ). Pronotum. Elongate, anterior margin slightly arched, posterior margin narrowly rounded ( Fig. 1A View FIGURE 1 ); lateral lobes longer than deep, narrowing to backward, humeral sinus absent ( Fig. 1B View FIGURE 1 ). Wings. Tegmina strongly short, not surpassing the posterior margin of pronotum, apices obtusely rounded; hind wings absent. Legs. Ventral margins of all femora without spine. Procoxae swollen with 1 spine; protibiae and mesotibiae with 4 internal spines, 5 external spines and 1 pair of apical spurs on ventral surfaces. Hind tibiae with 25–29 internal and 27–30 external spines on dorsal surface, apices bearing 1 pair of dorsal spurs and 2 pairs of ventral spurs. Abdomen. Posterior margin of tenth abdominal tergite significantly projecting with a small median concavity. Cerci densely setose; basal half of cerci stout, slightly narrowing in lateral view ( Fig. 1D View FIGURE 1 ), internal margin lobate expansion with 1 large conical process on dorsal surface ( Fig. 1F View FIGURE 1 ) and 1 small conical process on ventral surface ( Fig. 1G View FIGURE 1 ); apical half slender and spine-shaped which slightly incurved, apices subacute ( Fig. 1G View FIGURE 1 ). Subgenital plate longer than wide, basal area with triangular membranous area in middle, lateral margins terminating, apex triangularly projecting ( Fig. 1G View FIGURE 1 ). Styli densely setose and roughly conical, faintly curving forward, apices obtuse, inserted at the subapical area of subgenital plate on ventral surface ( Fig. 1H View FIGURE 1 ). Genitalia membranous.
Female. Posterior margin of tenth abdominal tergite faintly projected. Epiproct tongue-shaped, dorsal surface furrowed along the midline, posterior margin rounded ( Fig. 2C View FIGURE 2 ). Cerci very short and conical, gradually narrowing, apices acute. Subgenital plate triangular in ventral view, wider than long; baso-lateral areas roundly expanded, curving dorsad; posterior margin narrowly rounded ( Fig. 2E View FIGURE 2 ). Ovipositor slightly upcurved behind middle area, dorsal and ventral margins smooth, dorsal valvulae slightly longer than ventral ones, dorsal valvulae with apices acute, apices of ventral valvulae hook-shaped ( Fig. 2G View FIGURE 2 ).
Coloration. Body yellowish brown. Eyes black. Antennae with light brown rings on each segment. Dorsal surface of head with 2 pairs of longitudinal brown stripes, the lateral stripes extending to the posterior margin of pronotum. Scapes and pedicelli brown. Disc of pronotum light brown between lateral stripes. Apices of femora and basal areas of tibiae brown. Apices of tegmina yellowish brown. Abdominal tergites brown. Subgenital plate yellowish brown.
Material examined. Holotype: male, Dajianshan, Maguan , Yunnan, July 28, 2021, coll. by Xun Bian and Wei Bin . Paratypes: 2 males and 3 females, the other information as holotype.
Measurements (mm). Body: ♂ 7.9 – 9.0, ♀ 9.1 – 9.5; pronotum: ♂ 4.3 – 4.5, ♀ 4.0 – 4.7; tegmen: ♂ 4.0 – 4.5, ♀ 3.7 – 4.1; postfemur: ♂ 8.7 – 9.7, ♀ 8.9 – 9.3; ovipositor: 4.1–4.4.
Distribution. Yunnan (Maguan).
Discussion. The new species can be distinguished from the other species of the genus by the shape of male cerci and male subgenital plate.
Etymology. The name of the new species is derived from male cerci with two conical processes at the basal area.
