Figs. 3q–v , 6a , 14 , 28 .

Description. Male. Forewing length 16–17 mm. Forewing with relatively sharp apex. Upperside brown with light yellow border (width about 1 mm). Wing upperside strongly lightened (on forewing in costal margin and basal area, on hindwing whole surface). Underside light with bright colorful elegant pattern. Cubital eyespots on forewing are slightly enlarged. Veins on hindwing underside are silver. Female. Fore wing length 16.5 mm. Upper side bright, without pattern; underside pattern is thin and elegant. Eyespots on underside are centered by white color in 3 out of 5 available specimens.

Diagnosis. This new subspecies in comparison with other subspecies has more narrow forewings in males, very light-colored wings on the upperside and very thin beautiful pattern on the underside.

Etymology. The name is toponimic.

Material examined. Holotype, male, W. Mongolia, Hovd aimak, 15 km S Khara-Us-Nuur lake, 1300 m, 12-VIII-2004, leg. R. Yakovlev & D. Ryzhkov ( ZISP) . Paratypes: 2 males, same data ( RYB) , 1 male, 1 female, W. Mongolia, Hovd aimak, 50 km W Hovd, 1485 m, 4-VII-2004, leg. R. Yakovlev & D. Ryzhkov ( RYB) ; 1 female, Ms.Alt. [ai] coll. Erschoff ( ZISP) .

Distribution. Western Mongolia (Great Lakes Valley). Area of this subspecies limited very well by deserts that surround the Great Lakes.

Triphysa nervosa mongolaltaica Dubatolov, Korb et Yakovlev , ssp. n. https://zoobank.org/ urn:lsid:zoobank.org:act:D20B7F83-E31C-4880-A806-F5B491279B63

Figs. 4a–h , 6a , 15 , 29 .

Description. Male. Forewing length 17–19 mm. Wings brown with relatively wide pale edge. Costal edge and distal parts of cubital veins on forewing are light. Veins on wings’ underside are light, eyespots with no white centers, small. Female. Forewing length 17–18 mm. Upperside light, without pattern. Underside pattern is strongly diffused. Eyespots with no white centers.

Diagnosis. This subspecies is closely related to T. nervosa glacialis , but it differs from it by its larger size; by white-accented distal parts of cubital vein on forewing upperside; by highly diffused pattern on female wings’ underside.

Etymology. The name is toponimic.

Material examined. Holotype, male, Mongolia, Hovd aimak, Bulgan-Gol basin, middle stream of Ulyasutai-Gol river , 2500−3000 m, 25−26-VI-2004, leg. R. Yakovlev & D. Ryzhkov ( ZISP) . Paratypes: 12 males, 3 females, same locality ( RYB) ; 14 males, 6 females, SW Mongolia, Gobi-Altai aimak, Mongolian Altai Mts., Khasgt-Khairkhan Mts. , 17 km SSW Zhargalan, 19–21-VII-2010, 2500–2900 m, 46°48’N, 95°49’E, leg. R. Yakovlev & E. Guskova ( RYB) ; 4 males, W. Mongolia, Hovd aimak, Bulgan-gol basin, Bayan-Gol river valley, Arshantyn-Nuruu Mts. , Ulyastajn-Sala river , 1900 m, 46°21’N, 91°08’E, 9.-10-VI-2011, R. Yakovlev leg. ( RYB) .

Distribution. Mongolia (Mongolian Altai Mts.). Area of this subspecies on all sides by vast desert territories is restricted: Nuurdun from east and north and Gashun Gobi, Dzhungarian Gobi and Alashan deserts from west and south.
