Neoperla ussurica Sivec & Zhiltzova, 1996

( Figs. 38–42 )

Type locality: Russia, Primorsky Krai, River Ussuri, 6 km from village Stepanovka (N44°57’ E133°32’). Neoperla ussurica Sivec & Zhiltzova, 1996 — Sivec & Zhiltzova 1996: 14. (original description of the male, female and larva); Teslenko & Zhiltzova 2009: 50. (monography); Stark 2010: 7. (first records from South Korea); DeWalt et al. 2014 (catalog).

Literature data. Stark (2010): South Korea, Kangwondo, Chuncheon Nam, Myson, Magog-li (Gangwon Province, Chuncheon City), Malaise trap in larch planted forest, 70 m, N37°43.786’ E127°34.689’, 24.V.–12.VI.2004, leg. Pierre Tripotin: 1♂.

Material examined. NORTH KOREA: Pyongyang Capital city, Pyongyang, at light in the garden of Hotel Pyongyang, 25 m a.s.l., N39°00’ E125°45’, 06.VIII.1971, leg. Sándor Horvatovich, Jenő Papp: 1♂ ( HNHM; terminalia and aedeagus cleared in KOH and stored in the same vial).

Remarks. Our specimen agrees well with the original description of the species, the only slight difference is the more extended field of spinules on the aedeagal sac ( Figs. 38–40 ).

Distribution and ecology. The species is widely distributed in the Amur Basin in Russia and reaches the central portion of the Korean Peninsula, but was not presently collected in northeastern China ( Figs. 41–42 ). It is a potamal species, both Korean specimens were caught at large rivers. The South Korean male probably emerged from the Bukhan River, while the present North Korean specimen probably came from the Taedong River.
