Holotype male, China: Henan Province, Xinyang City, <a href="http://tb.plazi.org/GgServer/search?materialsCitation.longitude=114.25486&amp;materialsCitation.latitude=31.949566" title="Search Plazi for locations around (long 114.25486/lat 31.949566)">Dongzhai National Nature Reserve</a> (Fig. 11), 31.94956609° N, 114.25485947° E, 160 m, 6-IV-2021, Si-Kai, Du (ICJUST). Paratypes: four males and five females, same locality and date as holotype (ICJUST).</p> <p>Etymology. The species is named for Mr. Xu Chong who has helped the authors in previous works.</p> <p>Remarks. The new species can be easily distinguished from its congeners by the presence of projected lobes on male abdominal terga 7–9 and smaller humps on previous tergal segments. In I. sextuberculata, the finger-shaped lobes are present on terga 4, 7 and 8 (Huo &amp; Du 2020). Other species of Isoperlinae with abdominal processes include Isoperla distincta Nelson, 1976 from North America, Kaszabia digitata (Kawai, 1963), Isoperla sp. (Maruyama &amp; Hanada 2016) from Japan, and Kaszabia nigricauda (Navás, 1923) from Mongolia and Russia. Locations of tergal lobes on these species are on different segments than those found on the new species.</p> </div>	http://treatment.plazi.org/id/03E387930B2FFFBEFF3DFF17905AF85B	Public Domain	No known copyright restrictions apply.

Paraprocts long, triangular.</p> <p>Habitat. This species was collected crawling across the sandy bank of the Nenjiang River (Fig. 12), a large, perennial, braided, sand river. The sandy habitat made the specimens always accompanied with sand when collected by hand (Fig. 12D). Riparian vegetation of the collecting location was poorly developed, but the vegetation on the opposite shore was well developed (Fig. 12).</p> <p>Remarks. Adult morphology of the new specimens is generally identical to the drawings in Teslenko &amp; Zhiltzova (2009).
