Diagnosis.

Tetraserica pseudoliangheensis sp. n. differs from T. falciformis by the dorsal lobe of right paramere having a sharp hook at its apex (dorsal view). The species is also rather similar to T. liangheensis Liu et al., 2014; however, in the new species the posterior margin of metafemur does not possess a tooth and the dorsal lobe of the right paramere is much wider at the base.

Etymology.

The species name (adjective in the nominative singular) is derived from the combined Latin words pseudo- (nearly) and the species name liangheensis , with reference to the similarity to T. liangheensis Liu et al., 2014.
