The long-legged chafer Hoplia spectabilis Medvedev was described in 1952. Its occurrence was rarely reported and the document about its morphological details was not found. However,the chafer did frequently break out at Buha River valley in Tianjun county,Qinghai province,China since 2005. In this paper,we present a comprehensive description and illustrations of morphological characteristics of H. spectabilis from local collection,including developmental stages of adult,egg,larva and pupa. Among them,characteristics of the larva and pupa,the male genitalia as well as the difference between male and female are described for the first time. The morphological data will be quite useful for identification and characterization of the chafer,a poorly known species. It will also be an important basis for the chafer control when it breaks out.
