Systematics of the new genus Spinosuncus Chen Zhang Li with descriptions of four new species (Lepidoptera Crambidae Pyraustinae)

摘要

The new genus Spinosuncus>gen. n. is proposed for three known species, S.contractalis (Warren, 1896), >comb. n., S.praepandalis (Snellen, 1890), >comb. n., and S.aureolalis (Lederer, 1863), >comb. n. and four new species, S.rectacutus>sp. n., S.brevacutus>sp. n., S.curvisetaceus>sp. n., and S.quadracutus>sp. n. from the Oriental Region. An identification key is provided for all species. The habiti and genitalia of all species are figured. The monophyly of the genus is well supported by a phylogenetic analysis based on sequence data of the COI, 16S rRNA, and EF-1α genes. The potential sister groups of the new genus, the interspecific relationships and some intraspecific variations within the genus are discussed.
