Remarks.
Both sexes of
A.
coreana
were described by
Namkung
(1989)
from Korea. The male from Japan well agrees with that of the figure made by N a
m
k u n
g
. The figure of female by N
am kung
strongly resembles that of
A.
montana
Hayashi, 1986
, from Japan, but the opening part of epigynum of
coreana
seems wider than that of
montana
.
This species is new to the fauna of Japan, on the basis of the male specimen.
