Fig. 1

Description. ­Holotype­Male. Body small. Fastigium verticis shovel-shaped, with a indistinct longitudinal sulcus in the midline, protruding forward, apex rounded ( Fig. 1A ). Eyes globular, protruding outwards. Apical segment of maxillary palpi almost as long as subapical one, apex slightly swollen. Anterior margin of pronotum straight, posterior margin obtusely rounded ( Fig. 1D ); lateral lobe longer than deep, humeral sinus comparatively distinct ( Fig. 1B ). Thoracic auditory spiracles peanut-shaped, exposed. All femora unarmed on ventral surfaces. Fore coxa with a short spine; fore tibia with 3–5 long spines on inner side and 2–5 short spines on outer side of ventral surface; fore tibial tympana oblong and open on both sides. Middle tibia with 2–4 short spines on inner side and 4–5 short spines on outer side of ventral surface. Hind tibia with 21–30 spines on inner margin and 23–32 spines on outer margin of dorsal surface, with 2 pairs of ventral apical spurs and 1 pair of dorsal apical spurs. Tegmina developed, surpassing apices of hind femora; hind wings slightly longer than tegmina. Tenth abdominal tergite broad, posterior margin distinctly concave ( Fig. 1E ). Cercus short and stout, base slightly broad, apex rounded; inner surface of base with one short and stout process ( Fig. 1E ), inner surface of basal half longitudinally concave. Genitalia sclerotized, apex with 5 lobes, posterior margin concave in dorsal view; the lobe short and broad, covered with some small spines; ventral lobes short in lateral view, smooth; middle lobe smooth, base broad and apex narrow, which embedded among lobes ( Fig. 1G–I ). Subgenital plate long and narrow, base slightly broad, basal margin concave; middle area narrow; apical area slightly broad and posterior margin truncate. Styli cylindrical, apices rounded, inserted on apices of lateral margins of subgenital plate ( Fig. 1F ).

Female. Cercus conical. Ovipositor moderately upcurved, ventral valvula with apex hook-shaped ( Fig. 1K ). Subgenital plate quadrilateral, base slightly broad, tapering apically, apex rounded ( Fig. 1J ).

Coloration. ­ Body green. Eyes light brown. Disc of pronotum with a pair of longitudinal yellow stripes. Ventral surface of hind femur brown.

Distribution. China (Guangxi).

Discussion. ­ This new species resembles Shoveliteratura triangula Shi, Bian & Chang, 2011 , but it differs from the latter by male tenth abdominal tergite, cercus and genitalia.

Etymology. ­ The name of new species is derived from apex of male genitalia with 5 lobes; Greek penta - means 5 and lob- means lobe.
