Leptocera (Scotophilella) Czernyi. — Duda, 1925: 156 [generic combination]. Limosina (Limosina) Czernyi. — Duda, 1938: 117 [subgeneric combination, redescription, illustr.]. Opalimosina (Hackmanina) czernyi.— Roháček, 1983: 143–144 [generic combination, redescription, phylogenetic notes]; Roháček, 1985: 162–163 [illustr.]. Limosina czernyi.— Papp, 1984: 97 [Palaearctic catalog]. Limosina (Scotophilella) Lambi Duda, 1928: 143 [both sexes]. Type locality: England, New Forest. [synonymy]. Leptocera (Limosina) lambi.— Richards, 1930: 294 [generic combination]. Opalimosina (Hackmanina) czernyi.— Hayashi, 2010: 309–319 [diagnosis, illustr.]. Opalimosina (Hackmanina) czernyi.— Dong, 2016: 52–81 [illustr.]. Diagnosis: An additional small inclinate setula present between inner occipital bristles and outer occipital bristles; mid femur basally with a group of setae (Roháček, 1985, Fig. 983); hind tibia without ventral preapical spur; S5 posteromedially with a large oval area, densely covered by small blunt cuticular projections (Roháček, 1985, Fig. 1001). Material examined: CHINA: Liaoning: Fushu: 1♂, Donggualingcun, 1232 m, 10.vii.2022, Tao Li (M); 1♂, Laotudingzi, 1376 m, 28.v.2022, Tao Li (M). (all EMCAU). Comments: O. czernyi (Duda) is reported as a widespread Palaearctic species. Chinese records of this species are from Liaoning and Zhejiang previously (Cong et al., 2017; Dong et al., 2016). The record from Zhejiang suggests that it distributes in Oriental region, too. It is the only Opalimosina known from China that lacks hind tibial spur.
