Lathrobium nikkoense WATANABE 2001

Material examined Japan: Honshu: 1, Gunma Pref., Nikko District, Konsei pass, 1800-1900 m, 13.VIII.1980, leg. Hammond (BMNH).

Comment: The original description is based on type material from three localities in "Oku-Nikkô, Gunma Pref. " and additional material not included in the type series from two localities in Fukushima Prefecture (WATANABE 2001a). Based on the derived morphology of the aedeagus, particularly the shape of the internal structure (basal portion strongly inflated, apical portion spine-shaped), L. nikkoense is undoubtedly closely allied to L. sinense .
