Sweltsa QL 1 [temporary name]

Tibetisoperla sclerotica: Yan, Chen, Bozdogan & Li, 2022 , 125 (misidentification, the female and egg of this species unknown).

Supplementary description: Female head (lateral occiput) and median pronotum with rugosities ( Fig. 12A ); wing veins typical in this genus ( Fig. 12B ); subgenital plate triangular, with a large median notch ( Fig. 12C ).

Male: Unknown.

Nymph: Unknown.

Mature egg: General color brown. Oval in shape, collar absent. Length 370.7 μm, width 83.2 μm (n = 1). Chorion surface rough, irregularly covered with tiny shallow pits ( Fig. 12D–E ).

Material examined: 5 females, China, Qinghai Province, Qilian County, Zhamashigou , 2021-VII-9, 38.155274°N, 100.022593°E, 3010 m, leg. Huo Qing-Bo ( ICYZU), the same locality and date with Yan et al. (2022) .

Distribution: China (Qinghai).

Remarks: The subgenital plate of these females is most similar to Sweltsa ligula Rehman, Huo & Du, 2022 . The egg of S. ligula lacks a collar, yet the morphology is typical in this genus and also similar to several American species ( Stark & Baumann, 2007). The female adults often occurred under the rocks near the stream, but seldom inhabit in the riparian plants ( Fig. 13 ).
