The first record of the family Chloroperlidae (Plecoptera) from the Guangxi Zhuang Autonomous Region of southern China, with description of a new species of Sweltsa Ricker, 1943 

Abstract

The family Chloroperlidae is reported from Guangxi Zhuang Autonomous Region of southern China for the first time with a description of a new species of the genus Sweltsa, S. bilobata sp. nov. The new species is compared to two similar species.

A new species of the genus Sweltsa Ricker, 1943 (Plecoptera, Chloroperlidae) from Guizhou Province, China

“… Sweltsa was proposed by Ricker (1943) as a subgenus of Alloperla and given generic status by Illies (1966) . Presently, 11 species of this genus are known from China ( Wu 1938 , De Figueroa and Fochetti 2002 , Li et al 2014 , Li et al 2017 , Chen and Du 2017 , Dong et al 2018 , Mo et al 2020 , Li et al 2021a ). This study represents the first record of the family Chloroperlidae from Guizhou Province, China.…”

A new species of Suwallia Ricker, 1943 (Plecoptera, Chloroperlidae) from southwestern China, with an updated key to male Suwallia species

“…It consists of two subfamilies: Chloroperlinae Okamoto, 1912 and Paraperlinae Ricker, 1943. Presently, more than 29 species of the family Chloroperlidae are reported from China, belonging to six genera, namely: Alloperla Banks, 1906, Alaskaperla Stewart & DeWalt, 1991, Haploperla Navás, 1934, Suwallia Ricker, 1943, Sweltsa Ricker, 1943 and Utaperla Ricker, 1952 ( Wu 1938 ; Nelson and Hanson 1968 ; Du 1999 ; Li and Wang 2011 ; Li et al 2013 , 2014 , 2015a , b ; Chen and Du 2015 , 2016a , b , 2017 ; Dong et al 2018 ; Yang and Li 2018 ; Chen 2019 ; Mo et al 2020 ; Shi et al 2022 ).…”

A new species of Sweltsa Ricker, 1943 (Plecoptera, Chloroperlidae) and a supplementary description of Sweltsa hamula Chen & Du, 2017 from China

“…This genus is currently distributed in western and eastern Nearctic and eastern Palearctic/Oriental Regions ( Stark and Baumann 2007 , Kondratieff and Baumann 2009 , Stark and Baumann 2021 , DeWalt et al 2022 ). Presently, 14 species of this genus are known from China ( Wu 1938 , Du 1999 , Figueroa and Fochetti 2002 , Stark and Sivec 2009 , Li et al 2014 , Li et al 2017 , Chen and Du 2017 , Yang and Li 2018 , Dong et al 2018 , Mo et al 2020 , Li et al 2021 , Rehman et al 2022a , Rehman et al 2022b ). Most of these recorded species bear a prominent transverse ridge on tergum 9 and this was previously considered as an obvious characteristic of the genus Sweltsa .…”
