Paratype. 1♀, same data as holotype. Diagnosis. Only one pair of long spines on the pronotum present, located at the anterior margin in both sexes can be distinguished, and the male occipital with only one pair of spines can be separated from other species (Fig. 3–4, 10A).

General coloration green. Head. Globose, longer than wide. Compound eyes black and rounded. Antennae long, longer than forelegs. scapus rectangular; pedicellus shorter than scapus and the third segment. Occiput indistinctly swollen, with three pairs of spines on both sides of the median longitudinal sulci; anterior pair of spines very small; median and posterior pairs of spines strong and without branches (Fig. 3A, C, 10A). Thorax. Pronotum as long as the head, sparsely covered with a few small granules; transverse and longitudinal sulci distinct; only one pair of strong spines located at the anterior margins of pronotum. Mesonotum distinctly swollen, sparely covered with granules, top of the swollen part covered with spines; mainly with five pairs of strong spines on the mesonotum, the first pair of strong spines located at the anterior margins and without branches, the second pair of strong spines located slightly forward of the top of the swollen part and with a few branches, the third pair of spines just behind the second pair but located on the lateral side of the swollen part and with a few branches, the fourth pair of spines located slightly behind the top of the swollen part and with a few branches, the last pair of spines located near the posterior margin of mesonotum and without branches (Fig. 3C); the lateral carina of mesonotum with several spines. Metanotum rectangle, with mainly two pairs of strong spines, the first pair of spines located at the middle of metanotum, largest and with small branches, the second pair of spines located near the posterior margin of metanotum with one branch; the lateral carina of metanotum with one pair of spines. Abdomen. Cylindrical. Median segment not obvious. Terga II–IX with a prominent triangular, apically pointed lobe on the posterolateral angle (Fig. 3A–C). Terga II–V with three spines, two anterior spines located at 2/3 of tergites, largest and with one branch at base, one posterior spine on the middle of the posterior margin. Terga VI–IX with one spine postmedian margin of tergite. Anal segment covered with tiny tubercles, posterolateral angle and middle convex. Sternite VII with a flat praeopercular organ (Fig. 3E). Subgenital plate scoop-shaped, tapering posteriorly with a distinct median carina (Fig. 3E). Cerci long, slightly flat, not reaching the posterior margin of the anal segment (Fig. 3F). Legs. Slender. Profemora distinctly curved basally. All carinae of femora with distinct small serration (Fig. 3A– C). Pro- and mesofemora slightly shorter than pro- and mesotibiae. Metafemora slightly longer than metatibiae. Male. Small size.Apterous. General coloration brown with a black band running dorsally from head to abdomen (Fig. 4A). Head. Oval and smooth, longer than wide. Compound eyes black and rounded. Antennae filiform and long, scapus flattened, pedicellus shorter than scapus and the third segment, the third segment longest. Occiput with only one pair of strong spines (Fig. 4C). Thorax. Pronotum rectangular and smooth, a dark brown band across the pronotum, transverse and longitudinal sulci distinct, one pair of spines located at the anterior margin. Mesonotum almost 4x length of pronotum, indistinctly swollen at the 2/3 length of mesonotum; with eleven strong spines, the first pair of spines located at the anterior margins and without branches, three spines arranged irregularly on the front part of the top of the swollen part and without branches, the second pair of spines just behind the three spines but located on the lateral side of the swollen part and without branches, the fourth pair of spines largest with branches and located slightly behind the top of the swollen part, the fifth pair of spines smaller and located behind the swollen part, near the posterior margin of mesonotum (Fig. 4C); the lateral carina of mesonotum with several spines. Metanotum rectangle; with six spines, four spines horizontally located at the 1/2 length of metanotum, a pair of spines located near the posterior margin of metanotum; the lateral carina of metanotum with two spines. Abdomen. Cylindrical. Terga II–IX with a prominent triangular, apically pointed lobe on the posterolateral angle (Fig. 4A). Terga II–V with three spines; two anterior spines located at 2/3 of tergites, largest, a posterior spine on the postmedian margin of tergite (Fig. 4C–D). Terga VI–IX with one crest-like spine on the postmedian margin of tergite. Anal segment longer than tergum IX, posterior margin with shallow V-shaped emargination (Fig. 4D). Poculum cup-shaped, posterior margin rounded. Cerci flattened. Legs. Slender. Profemora base curved indistinctly. All carinae of femora and tibiae without distinct serration. Pro-, meso- and metafemora slightly shorter than pro-, meso- and metatibiae. Measurements. See Table 1. Distribution. China (Yunnan). Only known from the type locality.
