Cerci in posterior view, scale bar = 0.1 mm; 5. Terminalia in profile, scale bar = 0.1 mm; 6. Genitalia in profile, scale bar = 0.1 mm. Female. Unknown. Type material. Holotype ♂ , CHINA : Baima Snow Mountains , 4100m , 98°58'E , 28°18'N , Deqen , Yunnan Province, 17.vii.2017 , by Chuntian Zhang ( SYNU ). Paratypes , 2♂ , CHINA : Mt. Moirigkawagarbo , 3300 m , 98°88’E, 28°44’N, Deqen , Yunnan Province , 18.vii.2017 , by Xinyi Li ( SYNU ). Etymology. The specific name “scutiseta” is derived from two Latin words and refers to the extremely strong basal scutellar setae. Distribution. China ( Yunnan ).
