The description is based on two male specimens from Honshu (Iwate Pref.), Japan (JAEGER & WRASE 1994: 476). A third male specimen was recorded by ITO & JAEGER (2000: 1217). from Honshu (Nagano Pref.). The examined specimens from the Chinese mainland agree in external characters including the markant enlarged apical lamella and the construction of the internal sac of the median lobe with the Japanese specimens, however the median lobe is stouter and the apical lamella somewhat wider and shorter. Hence the identification of the Chinese specimens is provisional, investigation of further Japanese males is needed to get to know the possible range of variation in the external construction of the median lobe and for clarifying the taxonomic position of the Chinese specimens.
