Sinochlora semicircula sp. nov.

(Plate 7 a–e)

Holotype: male, China: Guangxi Prov.: Maoershan Mt., Jinshi, 2007. VII.20, Coll. Liu Chunxiang ( IZAS).

Description. Male (Holotype). Size large. Fastigium verticis dorsally sulcate, with obtuse apex; not deflexed, narrower than first segment of antennae, not touching fastigium frons. Antennae thin, long. Compound eyes moderately large, almost round. Pronotal disc with fully cylindrical prozona, and without lateral carina; anterior margin approximately straight, posterior margin obtuse rounded; median transverse furrow “V”-like. Lateral lobe of pronotum moderately higher than long; humeral sinus distinct.

Anterior coxae with a distinct spine. Anterior femur with 6-7 interior and 6 exterior ventral spines; median femur with 6 exterior ventral spines; posterior femur with 8 exterior and 7 interior ventral spines. Anterior tibiae dorsally sulcate and with 2 interior spines as well as 1 interior spine above tympana; median tibiae with 8 interior and 3 exterior dorsal spines; posterior tibiae with numerous exterior and interior dorsal spines. Each genicular lobe with 1 large middle sharp spine and 1 small lower one.

Tegmen extending beyond apex of posterior femur, hind wing longer than tegmen. Costa vein indistinct, Sc and R running closely until middle of tegmen. Rs vein branching slightly before middle of tegmen, bifurcate; R stem also with other 2 lateral branches.

Tenth abdominal tergum produced backwards, with lateral margins concave in middle; lateral forcipate processes gently decurved in apical half, middle protuberance indistinct, apical margin with distinct semicircular notch (Plate 7a,c). Epriproct rather short, wider than long, approximately trapeziform, dorsally sulcate; apical part upcurved, with two lateral posterior spines which directing dorso-apicad, notch between which wide trapeziform (Plate 7d). Cerci long, conical; exterior margin slightly concave in apical half, interior margin slightly convex in apical third (Plate 7b). Subgenital plate broad at base and very deeply cleft at basal third, and long arms strongly recurved and terminated with minute apical styli, notch between shaped into obtuse 60-degree angle (Plate 7a,e).

Female unknown.

Color. Green. Costal vein white and black, each tegmen with a black spot at base of the green subcostal vein.

Measurements (mm). length of body 36.0; length of pronotum 7.1; length of tegmen 50.5; largest width of tegmen 10.5; hind wing 58.2; length of anterior femur 8.9; length of median femur 13.0; length of posterior femur 33.5; length of anterior tibiae 11.5; length of median tibiae 15.0; length of posterior tibiae 36.5.

Etymology. The name shows that the new species possesses the apical margin of male tenth abdominal tergite with distinct semicircular notch.

Discussion. The new species distinctly differs from other congeners by the male tenth abdominal tergum with lateral margins concave in middle, lateral forcipate processes gently decurved in apical half, middle protuberance indistinct, apical margin with distinct semicircular notch (Plate 7a,c), and male epriproct wider than long, approximately trapeziform, with two lateral posterior spines at apex which directing dorso-apicad, notch between which wide trapeziform (Plate 7d).

Distribution. China (Guangxi Province).
