Coptotettix acutiangulus Zha sp. nov. from northern Thailand is described and illustrated with photographs. Morphological differences with a similar species C. annandalei are described in detail. C. acutiangulus Zha sp. nov. may be potentially distributed in Nepal. A brief discussion of the ecology and habitat of C. acutiangulus is given.
During the investigation of species diversity at the Lengshuihe Nature Preserve in Jinsha, Guizhou,China in Aug. 2015, a new species of the genus Bolivaritettix, B. jinshaensis Zha Wen sp. nov. was found.Herein we introduce it with description and illustration. It is similar to but differs from B. yuanbaoshanensis Zheng Jiang by： 1） vertex 1.8（♂） or 2.0（♀） times as wide as one eye; 2） in profile, vertex together with frontal ridge protruding and distinctly visible before eyes; 3） midkeel of pronotum interrupted or obscure between lateral keels of prozona; 4） pronotum and hind femur distinctly longer than those of the latter; 5）upper valvulae of ovipositor only 3.8 times as long as wide.
