Prismognathus davidis: Didier & Séguy 1952 : partim [plate 91, Figs. 1–2 ]. Misidentification.

Material examined. CHINA: Liaoning: 12 3, 8 ƤƤ, Dan-dong City, Laogugou, 26.VII.-11.VIII.2008, H.-C. Shan leg.; 2 3, 2 ƤƤ ( CHH, CYXW), Shenyang, no detailed data. Jilin: 2 ƤƤ ( IEAS), Changbaishan, Erdaokouhe, 14.VIII.1984, Z.-Y. Liu leg. KOREA: 6 3, 4 ƤƤ, Mt. Dulunsan, VIII.2009.

Identification. This species is distributed in the Russian part of Amur region and in northeastern China; there are no other species of Prismognathus living in the same area.

Diagnosis. The large and medium-size males of P. dauricus are characterized by the absence of the subbasal teeth along the dorsal ridge of the mandible. The small males of P. dauricus are not easy to separate from those of P. klapperichi and P. davidis (apart for the different geographic distribution) unless the genitalia are examined. The females of P. dauricus are indistinguishable in external characters from those of the similar species, especially P. davidis . To identify the female of P. dauricus , a dissection is always needed. For more details see the keys below.

Distribution. Liaoning; Russia (eastern Siberia), Korea, Mongolia, Japan (Tsushima Island only).
