摘要
Species from the Trimeresurus popeiorum complex(Subgenus: Popeia) is a very complex group. T. popeiorum is the only Popeia species known from China. During the past two years, five adult Popeia specimens(4 males, 1 female) were collected from Yingjiang County, Southern Yunnan, China. Molecular, morphological and ecological data show distinct differences from known species, herein we describe these specimens as a new species Trimeresurus yingjiangensis sp. nov Chen, Ding, Shi and Zhang, 2018. Morphologically, the new species distinct from other Popeia species by a combination of following characters:(1) dorsal body olive drab,without cross bands on the scales;(2) a conspicuous bicolor ventrolateral stripe present on each side of males, first row of dorsal scales firebrick with a white ellipse dot on posterior upper part in male, these strips absent in females;(3) eyes firebrick in both gender;(4) suboculars separated from 3rd upper labial by one scale on each side;(5) ventrals 164–168(n = 5);(6) MSR 21.
