| Summary: | 碩士 === 國立臺灣大學 === 植物病蟲害學系研究所 === 86 === This thesis is to study the taxonomy of Plectoptera from Fushan to Wulai
at the water shed of Nan-Shih stream in Taipei Prefecture collected during
1996 June to 1998 June. Mature stonefly nymphs were collected from different
habitats and transported to the laboratory. They were reared in aquariums at
the laboratory until emergence and subsequently identified. Seven species in
6 genera and 3 families, including both nymphs and their adults, are reported
in the thesis. They are Cryptoperla formosana（Okamoto）of the family of
Peltoperlidae; Cerconychia brunnea Klapalek of Styloperlidae; Paragnetina
planidorsa （Klapalek）、Agnetina aequalis （Banks）、 Kamimuria formosana
（Klapalek）、Neoperla cavaleriei （Navas）and Neoperla formosana Okamoto of
Perlidae. Among them 5 species with their nymphs are described for the first
time. Keys to nymphs and adults of species are provided, and the distribution
of Plecoptera in the water shed of Nan-Shih stream are discussed.
