Type materials

Holotype. Male ( NIBR), Korea, Jeollanam-do, Mt Wolchulsan National Park, Dogabsa Temple (34°45′05′′ N, 126°39′45′′ E), 8 August 2006, leg. B.W. Kim. GoogleMaps Paratypes ( NPRI), three males and three females, data as holotype GoogleMaps .

Diagnosis

This new species resemble A. dimidiatus , A. kimi , A. rostratus by slender embolus penetrating the tegulum and no atrial septum but can be distinguished by a heartshaped conductor with rounded base in male palp and large genital opening situated in the middle of atrium, and a broadly cylinder-like copulatory duct in female.

Etymology

The specific name is taken from the type locality: Mt Wolchulsan.
