Phanoperla namcattien, a new stonefly from Vietnam (Plecoptera: Perlidae)

Abstract

The stonefly genus Phanoperla Banks is endemic to the Oriental region, and occurs from insular and peninsular Southeast Asia to the Indian subcontinent, including Sri Lanka and the Himalayas (Sivec et al. 1988, Zwick 1982), and 19 species are known from the region (Kawai 1968, Zwick 1982, Zwick 1986, Zwick & Sivec 1985, Stark 1983, 1987, Cao et al. 2007). Adults of four species of Phanoperla were recorded in Vietnam by Zwick (1986): P. imitatrix Zwick, 1986, P. malayana Zwick, 1982, P. simplex Zwick, 1982, and P. vietnamensis Zwick, 1986. Stark (1987) provided additional locality data regarding Phanoperla from Vietnam. As part of a series of studies of stonefly systematics in Vietnam, we are describing one new species of Phanoperla based on our samples from southern Vietnam.
