Type materials
Holotype. Male ( NPRI), Dolsan Island , Dadohaehaesang marine National Park, Korea, 26 February 2009, collected D.Y. Choi and B.W. Kim.
Paratypes. 1 ♀ ( NPRI), the same data as holotype ; 1 ♂ ( NPRI), the same collection, 13 October 2008, leg. B.W. Kim.
Diagnosis
This species is similar to A. napolovi Ovtchinnikov, 1999 , A. paiki Ovtchinnikov, 1999 and A. coreana ( Paik, 1992) in having male palpal organs with embolus not penetrating the tegulum and conductor surrounding the distal part of embolus and female epigynum with genital opening located on the lateral of atrium and without atrial septum and hood. The species can be distinguished by the presence of a median apophysis (absent in A. paiki ), embolus with a horseshoe-like bifurcated distal part (thickly linear in A. napolovi ); and in female by distinctly spiral copulatory duct (indistinctly wound in A. dimidiatus ), spermathecal head located on the inner side of copulatory duct (outer in A. coreana ).
Etymology
The specific name is derived from the special distal part (Latin, horseshoe) of embolus in male palpal organ.
