Etymology The specific name is a Latin feminine adjective ‘ ungulata ’, which means a periandrium with one pair of forked processes at the apex.

Male length (N = 3) (including tegmen): 14.7–14.9 mm , length of tegmen: 11.9– 12.1 mm . COLORATION. Body and tegmina brown with dark brown marks; vertex, pronotum and mesonotum mottled, median carina of pronotum dark brown; frons light brown with apex mottled fuscous; gena yellowish brown, dorsal portion and anterior portion of eye marked with darker brown color; eyes black, ocelli milk white; tegmina light brown, marked with darker marks, apical portion and costal area dark brown ( Fig. 11 A–D). HEAD AND THORAX. Head anterior margin angulated, about 80°; vertex pentagonal; disc flat; 1.1 times as long as wide, lateral margins highly raised; posterior margin raised; median groove full length of vertex, apex Y-forked ( Fig. 11 B–C). Frons disc flat, 1.4 times as long as wide, median longitudinal carina very short positioned at dorsal portion, lateral margins slightly sinuate, moderately raised ( Fig. 11D ). Frontoclypeal suture pressed, convex, clypeus convex. Rostrum extending beyond metatrochanter ( Fig. 11D ). Antennae short. Pronotum anterior margin truncate, disc pressed, lateral side thick and tended up, median carina weakly raised, ventral margin rolled upwards, postocular eminence evenly convex ( Fig. 11 B–C). Mesonotum humped, anterior margin convex, disc flat, without carina ( Fig. 11 B– C). Metatibia with six spines apically, metatarsal basal segment with two large spines and seven or eight small spines apically ( Fig. 11E ). Tegmina elongate, 12.9 mm in length, 5.4 mm in width, costal membrane 3.5 times as wide as costal cell at level of bulla; costal margin evenly convex, very weak undulated, apical margin convex, sutural margin truncate, apical and sutural angles convex; vein ScP+RA elevated ridgelike above plane of vein Pc+CA and crossing pustulate bulla, CuA forked, clavus with few crossveins; one subapical line present ( Fig. 12A ).

Scale bars = 0.5 mm. MALE GENITALIA. Pygofer ring-like, anterior and posterior margins sinuate, ventral margin truncate, dorsal margin sinuate ( Figs 11F , 12B ). Genital style ventral margin convex, dorsal margin weakly concave with process apically ( Figs 11F , 12B ). Male anal tube elongated and arched ( Figs 11H , 12B ). Phallic complex arched ( Figs 11G , 12 C–E). Periandrium tubular. Dorsal part of periandrium distinctly shorter than ventral part in lateral view, median lobe short and acute. Each side of lateral part of periandrium with recurved process which apex forked. Ventral part of periandrium distinctly slender and tapering in ventral view ( Fig. 12 F–H). Aedeagus bipartite; each side of apex without process; apex of lateral portion with ear-like prominence ( Fig. 12 I–K). Distribution Hainan Province , China .
