The type specimens deposited in the Insect Collection of Beijing Agricultural University. Key to separated genear of Stingaphalariini 1 Forewing without pterostigma or not distinct(fig.1C,3C)……Crastina Forewing with distinctly pterostigma(fig.6C)……2 2 Forewing with Rs strongly upturned toward anterior margin,far away apical angle;hind-leg tarsus shorter than tibia……Colpsoscena Forewing with Rs to ward apical angle(fig.6C);hind-leg tarsus longer or equal than tibia(fig.6F) ……Eustigmatia Loginova,stat.n. Type species:Eustigmatia tamaricina(Loginova,1974) Crastina multipunctata,sp.n.(fig.1,2) Holotype ♂,Tewo Co.(County)(1700 m),Gansu Prov.(Province),1980-Ⅷ-2;partypes 48 ♂ ♂,39 ♀♀,data same as holotype;34 ♂♂,27 ♀♀ Zhangye Co.Qilianshan Mt.(Mountain) (2700 m),Gansu Prov.,1993-Ⅴ Ⅰ-24;52 ♂♂,58 ♀♀,Liupanshan Mt.(2100 m)Ningxia Hui Aut.Reg.,1992-Ⅴ Ⅱ-30. Host plant:Myricariae germanica(L.)Desv. This new species resembles Crastina myricariae Loginova but differs from the latter in having parameres narrow at base,the hind angle with finger-lide process,the female dorsal valve shorter,and anus bigger.

This new species is similar to Crastina tamaricina(Loginova,1960),hut differs from the latter in having parameres narrower at base,and nearly quadrate at apex and black,forewings M+Cu_1 equal R. Crastina tibetiensis,sp.n.(fig.4) Holotype ♂,Nyingchi Co.(3050 m),Xizang Aut.Reg.,1978-Ⅵ-8;paratypes 2 ♂♂,place same as holotype,1978-Ⅵ-7,8. Host plant:Descurainia sophia(L.)Schur.(Cruciferae).
