Figures 1–2
Description. Male.
Body small. Face vertical. Fastigium verticis conical, apex obtusely rounded, with a narrow longitudinal furrow on dorsal surface (
Fig. 1A
). Eyes nearly spherical, projecting outwards. Apical segments of maxillary palpi slightly longer than subapical ones, apices faintly inflated. Pronotum short with the anterior margin straight and posterior margin narrowly rounded; lateral lobes longer than high, the posterior margin straight, humeral sinus indistinct (
Fig. 1A
–
B
).
Fore coxae with 1 small spine. All femora unarmed on ventral surfaces, apices of genicular lobes of hind femora obtusely rounded. Fore tibiae ventrally with 4 pairs of spines and 1 pair of apical spurs; tibial tympana nearly ovoid, the internal and external ones nearly equal in size. Middle tibiae with 3 internal spines and 4 external spines, apices with 1 pair of spurs on ventral surfaces. Hind tibiae with 28–33 internal spines and 27–33 external spines on dorsal surfaces, ventral surfaces with 2 internal spines and 5 external spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs.
Tegmina slightly beyond pronotum, reaching the middle of the 4th abdominal tergite or extending the anterior margin of 5th abdominal tergite. Hind wings slightly shorter than tegmina (
Fig. 1C
).
Posterior margin of ninth abdominal tergite slightly concave, lateral margins slightly extend backwards (
Fig. 1E, F
). Posterior margin of tenth abdominal tergite obviously concave with 1 pair of long processes (
Fig. 1D, E
), bases of the processes separated from each other (
Fig. 1D
), apical areas circular extension with the dorsal area contracted each other (
Fig. 1H
) and the ventral area swollen (
Fig. 1G
). Epiproct membranous and fused with tenth abdominal tergite (
Fig. 1I
). Cerci short, internal margins of apical half of cerci significantly expanded (
Fig. 1F
), internal margins concave; the middle of ventral margins with 1 small triangular lobe (
Fig. 1F
); interno-dorsal margins of apical area with 1 long triangular lobe, which subapical area slightly constricted and apex obtuse (
Fig. 1E
), interno-ventral margins with 1 long spine-shaped process which curved ventrally and slightly backwards, its apex slightly acute (
Fig. 1G
). Genitalia membranous. Subgenital plate longer than wide, with basal area broader, narrowing toward tip, lateral margins rolled dorsally, posterior margin arched (
Fig. 1I
). Styli cylindrical, apices obtuse, inserted on the ventral surface of subgenital plate near apical area (
Fig. 1E
).
Female.
Tenth abdominal tergite with posterior margin slightly concave in the middle. Cerci conical, apices acute. Ovipositor slender, slightly curved dorsally, dorsal and ventral margins smooth, ventral valvulae with a small hook at apices (
Fig. 1L
). Subgenital plate nearly semicircular, basal margin straight, posterior margin narrowly rounded (
Fig. 1M
).
Coloration.
Body yellowish brown (
Fig. 2
). Internal margins of antennal sockets, scape, pedicelli and the first segment of flagellum black brown, flagellum with brownish rings at apical area of each segment. Dorsal surface of head with 4 longitudinal black stripes, the external stripes extending to the internal margins of antennal sockets, the internal ones fused at the apices of fastigium verticis. Pronotum with a longitudinal black stripe in the middle, the external stripes black brown. Apices of middle femora, apices and bases of tarsi blackish brown, hind femora with black spots in the middle, fore and middle tibiae with black brown spines, spines of hind tibiae with black apices, apices of hind tibiae brown. Tegmina brown, with black spots. Abdominal tergites black brown with yellowish brown spots; sternites yellowish brown.

Etymology.
Named comes from the posterior margin of male tenth abdominal tergite with 1 pair of long processes.
