A new species of Nemoura (Plecoptera: Nemouridae) from Kyushu, Japan, with notes on male vibrational signals.

摘要

A new species of Nemoura from Japan is described from male and female adults. In addition, the male vibrational signals under solitary condition are described. The new species, N. sefuriensis sp. n. is similar to N. stratum Kawai, 1966 in adult habitus with somewhat shortened wings, but can be distinguished from N. stratum by lacking large sclerotized prolongation on hind margin of male tergum 8, and by having membranous female sternum 8 with a pair of weakly sclerotized small areas.
