描述:特征记述 前胸背板背面微凸,沟后区平。前胸背板侧缘宽平凹,中部稍前复为最小宽度侧叶长稍大于最大宽度,腹缘在前半部微凹,在后半部微凸,这两部分在相接处形成非常微弱的圆角。前复翅M脉在基部113的端部发出3分支到达后缘端部。前复翅和后翅均完全发育,前者最大宽度大于前胸背板长度,渐均匀变狭一直到宽圆形的翅端。前足基节不具刺。前足腿节微侧扁,明显“s”形弯曲背面凸,内缘微具脊,更细的基部内缘不具脊。前足胫节听器孔平,壳状。各足腿节膝叶具双刺。前足腿节背面基部3/4扁平。各足腿节腹面具小且不是较宽的刺。前足腿节腹面内缘具11或12刺,外缘具6刺,中足腿节腹面内缘无刺,外缘具15刺,后足腿节内缘无或具1刺,外缘具12-15刺。
雄性 肛上板长盾形,端部狭尖角形。尾须圆柱形,内弯,并向端部渐变狭,在端部稍扩大,外缘在扩大的基部具弱凹,扩大的端部具l浅的纵脊延伸到端部,纵脊在端部突出似l短的钝齿。下生殖板纵长且微突出,从稍超出其1/2处开裂,端部形成微向背面弯曲的平行细端叶,端部圆,等宽。
体色 后头和前胸背板紫红色,这种红色沿着前复翅后缘为较宽的条纹,渐变狭且在端部附近消失。前胸背板背面中纵向显示出稍浅一些的颜色。其余的部分可能在活着时为浅绿色,现在略带黄色,前复翅略为淡绿色。触角腹面为略带黑色的紫红色,背面颜色略浅端部显示出2宽的大距离的较淡黄色小环纹。前复翅在平圆形区域的翅脉间的所有小翅室中均具紫红色小斑点。各足跗节淡棕色。

  • 描述

    Cephalic femora slightly compressed and distinctly curved in a Phasmoid manner; dorsal surface convex, but with its internal margin weakly ridged, except in the more slender proximal portion. Cephalic coxae unarmed. Foramina of cephalic tibiae flattened conchate. Tegmina with median vein branching at end of proximal third, this branch sending three branches to the sutural margin distad. Pronotal disk with surface weakly convex to flattened caudal portion, lateral margins very broadly and evenly concave, the least width of disk meso-cephalad; lateral lobes slightly longer than greatest (caudal) depth, ventral margin weakly concave in cephalic half, weakly convex in caudal half, these portions forming a very weak rounded angulation at their juncture. Tegmina and wings fully developed, the former with greatest width decidedly greater than pronotal length, narrowing very slightly and evenly to the broadly rounded apex. Femora with genicular lobes bispinose. Caudal femora with dorsal surface deplanate in proximal three-quarters. Ventral femoral margins armed with minute but rather broad spines, as follows. Cephalic internal 11 and 12, cephalic external 6, median internal 0, median external 15, caudal internal 0 and 1, caudal external 12 and 15. Supra-anal plate elongate shield-shaped, with apex narrowly acute-angulate. Cerci cylindrical, curved and gradually tapering to near apex, where they are brifly enlarged, the external margins showing weak emargination at base of this enlargement, the apical enlarged portion with a low, longitudinal ridge extending to the apex, which there projects as a short, stout tooth. Subgenital plate elongate and slenderly produced, cleft for slightly over half its length, the two distal portions thus formed slender, parallel, curving very weakly dorsad, of nearly equal width in distal portions to their rounded apices.
