Tribe Sarimini Wang, Zhang & Bourgoin, 2016

Type genus

Sarima Melichar, 1903 .

Diagnosis

The tribe Sarimini was defined by Wang et al. (2016) based on a combination of characters of the hind wings: three lobed, with Pcu-A1 lobe more or less as wide as ScP-R-MP-Cu lobe, and Pcu single or branched; Pcu and A1 anastomosing on a short or longer distance; A2 non branched.
