Material examined. Holotype: ♂, mixed forest (36°29′ 35″N, 127°49′36″E, alt. 347 m), 5.3 km south of Beopju Temple in Mt. Songni, Songnisanmyeon, Boeungun , Chungcheongbukdo, 22 August 2011, T. B. Ryu GoogleMaps . Paratype: 1$, same data as holotype.
Etymology. The specific name comes from the type lo cality, Mt. Songni.
Diagnosis. The new species is similar to C. jiriensis n. sp. in the abdominal pattern, the embolus length of male palp, the interval between the embolic base and the conductor of male palp, the apophysis teeth number and the apophysis shape of male palpal patella, and the vesicle shape of female spermatheca, but can be easily distinguished from the latter by the normal cymbium tip of male palp, the epygine, the small size and the separated position of the anterior vesicles, and the curved copulatory duct connected with the anterior vesicle of female spermatheca ( Figs. 4 View Fig AE, 5L, M, 7PR).
