03AF6B47D26FFFF0FF30FBC7DB697868.taxon	etymology	Etymology. The genus name is derived from the Latin words mons and cola, which means mountain dweller.	en	Mi, Xiaoye, Han, Hongxiang, Pan, Zhao, Zhu, Chaodong, Cheng, Rui (2025): Montiscola gen. n., a new alpine genus of Gnophini (Lepidoptera, Geometridae, Ennominae) from Xizang, China, with brachypterous females. Zootaxa 5621 (5): 594-600, DOI: 10.11646/zootaxa.5621.5.7, URL: https://doi.org/10.11646/zootaxa.5621.5.7
03AF6B47D26FFFF0FF30FBC7DB697868.taxon	diagnosis	Diagnosis. Although Montiscola is clustered with Sciadia + Crocota, it differs distinctly from Crocota in both the wing shape and genitalia. Compared to Psodos (Müller et al. 2019: male genitalia Figs 35 – 48), the juxta of Montiscola lacks spines on its posterior arms, and the apex of the valva is broader. Montiscola is very close to Elophos (which is synonymized with Sciadia in Lee et al. 2024: we use Sciadia below and the comparison is mainly with former Elophos species (Müller et al. 2019 )), but it can be distinguished by the following differences: The antennae are filiform in both male and female in Montiscola, while they are bipectinate in males of Sciadia. The significant difference in the female wing shape is that the apex of the forewing is rounded in Montiscola but very pointed in Sciadia (Müller et al. 2019: plate 8, Figs 56 d, 56 g, 57 c). In the male genitalia (Fig. 7; Müller et al. 2019: male genitalia Figs 56 – 59), Montiscola possesses a broad and apically round valvae, while the apex of the valva in Sciadia is very narrow; the juxta of Montiscola is much slender and forked at the distal one-third, whereas that of Sciadia is broader and divided basally; a cornutus is absent in Montiscola, but present in Sciadia. In the female genitalia (Fig. 8; Müller et al. 2019: female genitalia Figs 56 – 59), Montiscola has a long and narrow ductus bursae, while the ductus bursae of Sciadia is stout.	en	Mi, Xiaoye, Han, Hongxiang, Pan, Zhao, Zhu, Chaodong, Cheng, Rui (2025): Montiscola gen. n., a new alpine genus of Gnophini (Lepidoptera, Geometridae, Ennominae) from Xizang, China, with brachypterous females.

03AF6B47D269FFF2FF30FD76D8A77AF0.taxon	biology_ecology	Biology. Field observations indicate this species demonstrates seasonal abundance within its specific ecological niche, showing particularly high population densities. Found at altitudes ranging from 4200 to 5000 meters (Figs 16 – 17), the species is characterized by brachypterous (short-winged) females, which implies an adaptation to endure cold temperatures, strong winds, and thin air. It appears to complete one generation per year, with its potential food sources being low shrubs.	en	Mi, Xiaoye, Han, Hongxiang, Pan, Zhao, Zhu, Chaodong, Cheng, Rui (2025): Montiscola gen. n., a new alpine genus of Gnophini (Lepidoptera, Geometridae, Ennominae) from Xizang, China, with brachypterous females.
