About Erebia maurisius Esper, 1800
This description of Erebia maurisius is taken from Seitz. The reddish-brown band on the forewing is divided by veins into several elongated spots, usually 6 in total. The cell is more or less filled with ferruginous brown. Behind the cross-vein, there are 2 somewhat diffuse narrow streaks that extend toward the distal band and disappear into it. The hindwing bears 6 round russet-yellow spots. On the underside of the forewing, the band is lighter in color. The space between this band and the darkened base of the wing is russet-brown, while the inner and distal margins are blackish brown. For males, the underside of the hindwing is dark brown, with very small, point-like russet-yellow spots. For females, the underside of the hindwing is grey-brown, finely dusted with greyish yellow; the ochre-yellow dots along the distal margin are elongated into small stripes. On the upperside of the wing, the cell has a diffuse whitish yellow spot. Fringes are grey-brown in males and whitish grey in females. The antenna is finely ringed; the club is white on the inner side and black-brown on the outer side. Adults fly in mid-July, found in the Altai at elevations between 2000 and 2700 m on grassy slopes.
