Holotype: male, P. R. China: Sichuan Province: Luding: Yanzigou , 2000–2600 m, 7. VII. 2006, Coll. JIAYU LIU.

Paratype: 2 males, same data as holotype ; 2 males, P. R. China: Sichuan Province: Luding: Yanzigou , 2000–2600 m, 7. VII. 2006, Coll. LIYONG FENG .

Etymology – According to the specific name of the resemble species, latilamella , we named the new taxon name as “ sublatilamella ”, the Latin word sub- refer to likeness.

Remarks – This species belongs to Phaonia oxystoma -group, and resembles Phaonia latilamella FENG et MA, 2002 , but it differs from the latter in eyes bare, ommatidiae not expanded on upper medium part; genal height about 1/5 of eye height; acr 1+1; spiracles dark brown; coxae of legs dark brown; the inner lobe of cerci of male wide and long, surstyli rather wide on apical part, the length of sternite 5 longer than its width.
