Historically the arctiid Syntominae was often confused with Zygaenidae, Sesiidae, Euchromiini and Ctenuchini due to the convergent wing shape and colour patterns. According to the phylogenetic hypothesis being more accepted in recent years, the subfamily comprises two tribes, the pan-Old World Syntominiand the Africa-restricted Thyretini.

The short tandem repeats is a kind of DNA sequence formed repeatedly and connectively subjected to a core unit of several base pairs.The non-interfered multi-PCR was applied with 3 loci in the same reaction system.By using the technique of denaturing polyacrylamide gel electrophoresis and silver stain,the allele frequencies distributions of 3loci:F13A01,FESFPS and vWA in 10 minority populations only resided in Yunnan Province:Bai,Dai,Achang,Jingpo,Deang,Lahu,Bulang,Hani,Pumi and Jino.A satisfactory result was obtained and some significant genetic differences were noticed in different populations.
