Middle Ural, Yamalo-Nenets Autonomous Okrug, Altai Mountain, Irkutskaya Oblast, Buryatia, Transbaikalia, Yakutia, Chukotka, Magadanskaya Oblast, southern part of Khabarovsky Kray, Primorye. Outside Russia: N Mongolia. Hostplants: Brassicaceae (Burnasheva 2011). Note. The subgenus Dysgnophos Wehrli, 1951 is currently represented by two species in the Baikal region: Ch. (D.) subsplendidaria (Wehrli, 1922) and Ch. (D.) turfosaria (Wehrli, 1922) (Beljaev & Mironov 2019). I studied about 50 specimens of Dysgnophos from different locations in Irkutskaya Oblast and Republic of Buryatia. Male genitalia were revealed to be rather variable in this sample, and some variants of this variability have been considered to be diagnostic at the species level by some authors (e. g. Wehrli 1922; Smiles 1979). Thus, Siberian Dysgnophos show different degree of sclerotization of the U-shaped cornutus (see Fig 17 J – 17 O), and inconstant number of spines on the costa of the valva has been found even within the same sample: from 0 to 2. The size and coloration of the adults are also markedly variable. Beljaev (2016) doubted the species rank of Ch. (D.) subsplendidaria. However, I found a female with some genital characters different from typical to Ch. (D.) turfosaria that could suggest separate species. The Ch. (D.) turfosaria species-group requires a revision based on more abundant materials.	en	Makhov, Ilya (2021): Geometridae (Lepidoptera) of the Baikal region: keys to species and an annotated catalogue.

Outside Russia: China (Inner Mongolia, Shanxi, Hebei, Beijing, Gansu, Qinghai, Sichuan). Hostplants: unknown. Note. The taxon reticulata was described together with monotypic genus Scardostrenia Sterneck, 1928. Later, Wehrli (1939) placed reticulata in the genus Proteostrenia Warren, 1895 according to its external morphology. Recently, this association was questioned (Makhov & Beljaev, 2019) and the original combination, Scardostrenia reticulata Sterneck, 1928, was restored. Simultaneously, D. Stüning (personal communication) paid attention on the evident similarity between the male genitalia of S. reticulata and Hypoxystis pulcheraria (Herz, 1905) (Fig. 19 E, 19 F). I studied the genitalia of a female S. reticulata and found the structure of its genitalia to correspond to the features of Hypoxystis Prout, 1915, particularly, the shape of the sterigma, hollow signum and the excavated posterior margin of the abdominal sternite VII. Thus, I agree completely with Stüning’s opinion and move S. reticulata in the genus Hypoxystis as follows: Hypoxystis reticulata (Sterneck, 1928) comb. nov. As Scardostrenia Sterneck, 1928 is a monotypic genus, it is therefore considered a junior synonym of Hypoxystis Prout, 1915 syn. n.	en	Makhov, Ilya (2021): Geometridae (Lepidoptera) of the Baikal region: keys to species and an annotated catalogue.

Recently S. strictaria was transferred to the genus Phthonandria (Müller et al. 2019) but in the new edition of the Catalogue of the Lepidoptera of Russia (Beljaev & Mironov 2019) it was kept in the genus Synopsia. Indeed, S. strictaria does not correspond to type species of the genus Synopsia, Geometra sociaria Hübner, 1799, and should be replaced in another genus within Gnophini. However, E. Beljaev points out (personal communication) that the genus Phthonandria is not appropriate for this species too. S. strictaria possesses a number of considerable morphological differences from the type species of the genus Phthonandria, Hemerophila atrilineata Butler, 1881, e. g. reduced proboscis, the absence of hair pencil on the hindtibia, small and weak uncus in male (in contrast to one in Ph. emaria, see Fig. 19 I).	en	Makhov, Ilya (2021): Geometridae (Lepidoptera) of the Baikal region: keys to species and an annotated catalogue.

1314BF10FFBAFFD8FF27FC79F46C9ACB.taxon	distribution	Distribution. Endemic to mountains of Southern Siberia. Altai, Tuva, Buryatia. Outside Russia in Mongolia. Hostplants: unknown. Note. The specimens mentioned above were collected close to the type locality of the A. heterogynoides, Munku-Sardyk Mountain. However, they conspicuously differ from each other in the shape of valvula, harpe and saccus (Figs 26 E, 26 G). Appearance of their genitalia has also some differences from the illustration of the genitalia “ Orthotrichia heteroginoides Whrl. ” provided by Vasilenko (2002: 557). Moreover, the curved shape of cornutus in these specomens corresponds to that in Pleotrichia Vasilenko, 2005. The diagnostic features of related species, i. e. A. karanguica Vasilenko, 2003, A. lysimeles (Prout, 1924) and P. kurenica Vasilenko, 2005 discussed earlier (Vasilenko 2001, 2002, 2005) evidently requires a reexamination. Due to the scanty material I assigned the Buryatian representatives of this genus with heterogynoides described from the neighbouring location.
