Notes.
This new species resembles
A. montana
Hayashi, 1986
, but is distinguished from the latter by the shapes of retorolateral apophysis on palpal tibia and copulatory ducts. This new species is smaller than
A. coreana
and
A. montana
, and its body length is less than
2.5 mm
.
Etymology.
This species is named after the collector, Dr. T. Kamura.
