DISTRIBUTION. Russia (South Siberia, Far East), Mongolia, Japan. This species was recorded from Kunashur, Shikotan and Iturup islands (Maslova et al., 2012: 76); here it is new for Chirpoy, Kharimkotan and Paramushir islands.

NOTES. Negrobov et al. (2005) used in their key to distinguish D. ptenopedilus from D.

plumitarsis and D. simius such variable characters as light colour of lower calypter setae and light at base segment 4 of fore tarsus. However, males of D. ptenopedilus are distinct in bearing curved apicoventral seta on segments 1–3 of fore tarsus. The other two species bear straight apicoventral seta on the same segments.
