Abstract

A new species ofPareasis described from Yunnan Province, China, based on morphological comparisons and molecular data. Genetically, the new species is most closely related to the recently-describedPareas geminatus, for which we present new topotypic findings. The genetic divergence (uncorrected p-distance) of the cytb gene between the new species and congeners ranged from 6.14% to 24.68%. Morphologically, the new species can be distinguished fromP. geminatusand all other congeners. Our work brings the total number of species within the genusPareasto 22.
