Comparative notes.

The original description was based on three type specimens from Guadun, Fujian ( Smetana 1996). Considerable interspecific variability of D. hamatum was observed not only in external characters such as body size, coloration, punctation, and shapes of head, pronotum and elytra (Fig. 1), but also in the shape of parameres and internal structures of aedeagus (Fig. 2A, B). The shape of the posterior margin of the male tergite VIII is constant (Fig. 2D). It is recorded here from Anhui, Zhejiang and Jiangxi for the first time. Some specimens were sifted from wet leaves and moss on the rocks near a stream at altitudes from about 460 to 910 m (Fig. 5).
