Abstract: In order to reduce insect molecular systematics research costs and improve resource utilization,dried specimens to extract genomic DNA were used.DNA was extracted from dried specimens and liquid dip samples of Pimeliinae kept in Museum of Hebei University for different storage life, which was used as template to amplify some specific gene fragments via PCR. No significant difference was noticed between those DNA from different samples. UPGMA phylogenetic tree was made up using the sequence information of Cytochrome B (Cytb) genetic fragments, and which was compared with traditional taxonomy to discuss the phylogenetic relationships of tribe Platyopini. Results support Reitter's opinion(2005) that Platyopini and Pimeliini belong to two tribes, negate Beutle's standpoint(1893) that belong to one tribe. This paper also provides experience for molecular systematic research of using dried coleoptera insect specimens.

Key words: Platyopini, dry preserved specimen, DNA extraction, phylogeny
