Figs. 1q–z , 6a , 22 .

Triphysa phryne striatula Elwes, 1899 ; Trans. Entomol. Soc. London 1899: 365.

Type locality: Kuruktagh near Korla [East Tian-Shan, Xinjiang, China]. “Lastly, there is a form found in the Kuruktagh near Korla, var. Striatula, Stgr. (MSS.) , which is distinguished by pale longitudinal striations on the fore-wing of the male. This form seems by the position of the spots to belong to phryne rather than to dohrnii” ( Elwes 1899) .

Description. Forewing length 17−18 mm. Upperside with light strokes between veins. Underside with expanded light pattern (in comparison to T. phryne ). White centers of postdiscal spots can be absent on both forewing and hindwing undersides. In addition to the white lines on the upperside, the eyespot between cubital veins on the forewing underside is somewhat larger than its neighbors.

Male genitalia. Aedeagus densely covered by teeth with caudally directed apex. Valva with much prolonged distal end and pointed obliquely truncated apex. Four specimens have been dissected.

Material examined. 1 male, Kuruktag ( ZISP) ; 1 male, Kutscha mont., Tian-Shan, 3000 m ( LNK) ; 4 males, 6 females, Korla ( ZFMK) ; 2 males, 2 females, Asia centr., Koterlbei (Korla?), April – Mai 1902 ( MHUB) ; 5 males, 3 females, Korla ( MHUB) ; 6 males, 4 females, Tian Shan, Merzb. ( ZSSM) ; 9 males, 15 females, Korla , Tancre coll. ( ZSSM) ; 2 males, 2 females, Asia centr., Koter (bei Korla), Mit. V-1902 ( ZMHU) ; 2 males, 3 females, Korla ( ZISP) ; 1 male, 1 female, Korla , coll. Deckert ( ZISP) .

Distribution. China: Xinjiang: East Tian-Shan, Kuruktag, Eastern part of Boro-Khoro.

Triphysa striatula urumtshiensis Dubatolov, Korb et Yakovlev , ssp. n. https://zoobank.org/ urn:lsid:zoobank.org:act:94F088B5-6F21-41B1-88CE-9821F6261F52

Figs. 2a–b , 6a , 23 .

Description. Male. Forewing length 20–21 mm, wings dark-brown. Eyespots of the postdiscal row on hindwing underside are almost equal in size and very small. Very wide light suffusion along the veins is present, especially in the central cell (almost touching the internal stroke); strong overall expansion of light pattern is present. Postdiscal row of eyespots in forewing underside with band between cubital and other eyespots, cubital eyespots are slightly larger. Female. Forewing length 18−20 mm. Upperside white or whitish, underside pattern as in male.

Diagnosis. Slightly larger than nominotypical subspecies. There is no lightening on upperside like in Triphysa striatula striatula .

Material examined. Holotype, male, Urumtchi ( ZISP) . Paratypes: 2 males, 1 female, Turkestan , Urumtchi, Ruckbeil, 1904 ( MHUB) ; 1 male, Kazakhstan, Boro-Khoro Mts. , 35 km N of Dzharkent, Sarybel environs, 1600–2000 m, 30-VI-2010, leg. S.K. Korb ( SKNN) ; 1 male, 1 female, Kuldscha , VII-1902 ( ZSSM) ; 1 male, Urumtchi ( ZISP) .

Distribution. China: Xinjiang Prov. (Urumqi environs); Kazakhstan: eastern part of Boro-Khoro Mts.; very local. The isolation border between T. striatula striatula and T. striatula urumtshiensis ssp.n. is in high-mountainous glaciers of Boro-Khoro and Sarmin-Ula Mountain ridges.
