The only species of Calvisia (Phasmatodea, Necrosciinae) from China, with a new synonymy and additional descriptions

Calvisia is a colorful winged stick insect genus consisting of 6 subgenera and 44 species widely distributed in temperate and tropical Asia. C. medogensis syn. nov. was discovered in Mêdog, Xizang (Tibet), China and is so far the only species recorded from China. We here propose that C. medogensis syn. nov. is a synonym of C. fuscoalata after checking type specimens of both species. New materials studied are deposited in Yunnan Agricultural University, China (YNAU).
