Systematic studies within the family Pterophoridae have been determined by external morpholgical characteristics (Yano 1963, Spuler 1910, Meyrick 1910). However, it is sometimes to be the result of species misplacement by the variation, depending on geographic isolation and genetic drift (Moran, 1986; Shufran et al., 2000; Anstead et al., 2002; Margaritopoulos et al., 2006). The genus Platyptilia Hübner [1925] is one of the largest genera of the family comprising more than 100 species according to the World’s Catalog by Gielis (2003) mainly distributed from Palaearctic and Afrotropical regions. Within the genus, Platyptilia ignifera has been suspected as very differentiated from other congeneric species in the morphological characters. In this study, to ascertain a placement of the species, we performed molecular analysis with one mitochondrial gene, COI and one nuclear gene, 28S, and morphometric analysis based on six ratios characters using principal components analysis (PCA). The sequences of the two genes, COI, 28S, implied that Platyptilia ignifera separated from Platyptilia spp. In addition, P. ignifera exhibited morphological characteristics distinct from other congeneric species. Based on these results, we propose that Neoplatyptilia gen. nov., for Platyptilia ignifera.
