7D4DD51AE053FFD9A7ABC5BD712911D5.taxon	diagnosis	Diagnosis: Small size, body length 10 ~ 15 mm; macropterous, wing length 10 ~ 15 mm, general color dark brown; triocellus, area between posterior ocelli to compound eyes yellow brown. Pronotum width twice its length, darkcolored medially with rugosities, with a smooth longitudinal band present among the centerline. Terga 9 – 10 of male heavily sclerotized posteriorly, posteromedial margin of tergum 10 undivided, with a developed sclerotized process (Fig. 1 A – B) with wide lateral grooves on surface. Vesicle on sternum 8 reduced. Aedeagus membranous, short columnar, without any sclerites but covered ventrally by patches of fine spines. Female coloration similar to male, posterior margin of tergum 10 usually sclerotized and extending as a process like the male (Fig. 1 C – D). Subgenital plate rounded or short triangle, often with a median notch apically.	en	Huo, Qing-Bo, Du, Yu-Zhou (2020): A new genus and two new species of stoneflies (Plecoptera: Perlodidae) from Guizhou Province, China.

Zootaxa 4718 (4): 470-480, DOI: https://doi.org/10.11646/zootaxa.4718.4.2
7D4DD51AE053FFD9A7ABC5BD712911D5.taxon	discussion	Remarks: We previously treated P. oncocauda as a species of Isoperla Banks, 1906 based on the wing venation (Banks 1906) and aedeagal morphology (Sandberg & Kondratieff 2013, Szczytko & Kondratieff 2015). The wing venation and the paraprocts of Parisoperla are most similar to Isoperla, indicating a placement in the subfamily Isoperlinae. Within the Isoperlinae, several genera such as Calliperla Banks, 1948, Cascadoperla Szczytko & Stewart, 1979, Clioperla Needham & Claassen, 1925, Cosumnoperla Szczytko & Bottorff, 1987, Kaszabia Raušer, 1968 and Mesoperlina Klapálek, 1921 are also similar to the new genus. However, the male tergum 10 of Clioperla and Mesoperlina is cleft. The male of Kaszabia can be distinguished by a pair of tergal processes of the abdomen (although these processes are not a unique character of this subfamily, present also I. distincta Nelson, 1976 a Nearctic species of Isoperla) (Teslenko & Zhiltzova 2009, Judson & Nelson 2012, Szczytko & Kondratieff 2015); The monotypic Calliperla from western North America has the male tergum 10 short and broad, crescent-shaped, with a terminal process as well, but the process curving forward and upward, just as similar as Cosumnoperla. The aedeagus of Calliperla and Cosumnoperla are more complex in structure than the new genus (Bottorff 2007, Szczytko & Stewart 1984). Discussion: Geographically, the 15 known Chinese Isoperla species are mainly distributed in Palaearctic Region of China. Whereas Parisoperla is apparently restricted to Guizhou and Zhejiang provinces, which are considered the northern portion of the Oriental Region (Ma 1959, Zhang 2011). Therefore, we speculate that the genus may be an Oriental group of stoneflies.	en	Huo, Qing-Bo, Du, Yu-Zhou (2020): A new genus and two new species of stoneflies (Plecoptera: Perlodidae) from Guizhou Province, China.

7D4DD51AE053FFD9A7ABC1D1763212E4.taxon	discussion	Remarks: Only a single nymph available of the new genus from Tianmu Mountain was available for study. In the new genus, the Y-arms of the mesosternum and mandibles appear to be most similar to nymphs of Calliperla and Isoperla (Szczytko & Stewart 1984, Stewart & Stark 1993). The lacinia of P. oncocauda is similar to C. luctuosa (Banks, 1906) with the apex curved and inner margin straight (Szczytko & Stewart 1984), but the inner lacinial setal row of P. oncocauda is only present on the anterior apex angle, not reaching the base and sparser than C. luctuosa (about 8 thick setae and 20 fine hairs). No additional seta or setal patches occur on the surface of the lacinia.	en	Huo, Qing-Bo, Du, Yu-Zhou (2020): A new genus and two new species of stoneflies (Plecoptera: Perlodidae) from Guizhou Province, China.

7D4DD51AE055FFD0A7ABC38177BF128A.taxon	discussion	Remarks: This species is similar to P. kuankuoshuiensis, except for the longer process on male terminalia and smaller paraprocts (Fig. 14). It is also similar to P. oncocauda, but the sclerotized areas on terminalia are different in shape. The posteromedial margin of tergum 10 of the male of P. leigongshana is narrowed in dorsal view. Parisoperla oncocauda bears a process which is wider at posteromedial tergal margin and tapers distally.	en	Huo, Qing-Bo, Du, Yu-Zhou (2020): A new genus and two new species of stoneflies (Plecoptera: Perlodidae) from Guizhou Province, China.
