Distribution. Previously known only from the Russian Far East, this species is recorded in China for the first time. In China, it was found in the Fenglin National Nature Reserve, located on the northern section of the southern slope of Lesser Khingan Mountains in northeast Heilongjiang Province.

Remarks. This species was also collected from the Lesser Khingan (Xiao Hinggan Range), the same mountain range as mentioned in Teslenko (2019). Based on the structure of the epiproct that divided longitudinally into ventral and dorsal halves, and the presence of the posteromedial process on male tergum 7, C. khingana was provisionally assigned to the C. atra species group ( Zhiltzova 2001; Teslenko, 2019). However, upon examination of its visible characters, it was identified as a member of genus Capniella , instead of a member of genus Capnia for the following reasons. Forewing: R1 vein strongly curved, A1 vein straight, typical of Capniella ( Fig. 1a View FIGURE 1 ). There are slight differences in curvature of the A 1 in forewing from that described in Teslenko (2019), but such differences of curvature of the A1 veins had been already suggested Capniella ( Murányi et al. 2014) . Hindwing is generally similar to the types ( Fig. 1b View FIGURE 1 ). The male subgenital plate is weakly fused with the base of the sternum 9, and the base of the sternum is weakly fused with the tergum as well ( Fig. 2a–c View FIGURE 2 ), however, those are also widely fused in Capnia sensu stricto ( Fig. 2e View FIGURE 2 ). The fusion plate is very broad ( Fig. 2d View FIGURE 2 ), a character typical in Capniella , whereas the plate is medium wide in Capnia sensu stricto ( Fig. 2e View FIGURE 2 ). The lower portion of the main sclerite is sclerotized, basally narrowing and long, apex weakly sclerotized and hook curved upward then downward with a wide and blunt apex ( Fig. 3a–b View FIGURE 3 ) which is not clearly described and shown in original illustrations in Teslenko (2019); in fact, that character is most closely related to Capniella gibba Hwang, Li & Murányi, 2021 .
