Two new species of Amphinemura (Plecoptera, Nemouridae) from the southern Qinling Mountains of China, based on male, female and larvae

Abstract

Two new species of the genus Amphinemura, A. albicauda sp. n. and A. dingoidea sp. n. from the southern Qinling Mountains, Foping County of Shaanxi Province, western China, are described based on both sexes and the larval stage. The new species are compared with related taxa, and the A. sinensis species group is defined for an Oriental lineage of the genus. Amphinemura sinensis (Wu, 1926) and A. unihamata (Wu, 1973) are reported from Shaanxi for the first time, and the hitherto unknown female of A. unihamata is described. A distribution map of the Amphinemurinae known from Qinling Mountains is given.
