Recent studies have clarified the nomen cla ture dojana floresina sp. n. (male holotype in Senck en bergMu of the family (Nässig & Oberprieler 2007) and of the se um Frankfurt am Main, Germany). The species, one of the easternmost representatives of the genus in the In do ne 53 currently recognised genera (Näs sig & Ober prie ler si an archipelago, is rather bright in ground colour but with 2008) and have begun to address the com po si tion of a welldeveloped dark pattern. Main diagnostic dif ferences natural groups (subfamilies) in the fa mi ly (Ober prieler are found in the com para tive ly small male geni talia. et al. 2003) and their rela tion ships (Zwick 2008).

The such group is the “Ganisa group”, an infor mal collective species appears to have more than one gene ra tion per year; group proposed by Oberprieler et al.
