Abstract
The species in genus Campsosternus Latreille, 1834 are few of the click beetles which have metallic colors. This genus contains about 80 species mostly from Oriental realm, with an exceptional species: C. papuensis Van Zwaluwenburg, 1931, distributed in Papau New Guinea in Australian realm. According to references, 5 species was recorded in Taiwan: C. auratus (Drury, 1773), C. guishuni Ohira, 1977, C. mirabilis Fleutiaux, 1930, C. watanabei Miwa, 1927, and C. yasuakii Suzuki, 2002. The diagnosis is based on adult morphology: body size, body color, maculation, antennal length-width ratio, and compare the male genitalia. However, the species is difficult to identify due to the highly variable body color and maculation. Therefore, a molecular phylogeny study of Campsosternus in Taiwan was conducted in this study by molecular marker. The results of mitochondrial DNA COI and 16S rDNA show excellent resolution on species level. Both genes support that C. gemma Candèze, 1857, C. watanabei, and C. yasuakii are three independent taxa. C. mirabilis and C. yasuakii cannot be separate from each other and should be treated as synonym. C. guishuni has only one collection female type specimen as representative. It needs more evidence to check whether C. guishuni is a variant of C. mirabilis or not.
