Diagnosis This species is similar to A . dimidiatus ( Paik, 1974 ) , A . kimi ( Paik, 1974 ) , A. euini ( Paik, 1976 ) , A . bifidus ( Paik, 1976 ) , A . ovatus ( Paik, 1976 ) , A . rostratus (Song et al., 1993) and A . jaegeri (Kim, 2007) in having slender embolus penetrating the tegulum of male palp and epigynal atrium wider than long and copulatory opening located under the lateral atrial margin.
