description: <i>Amphinemura coreana</i> Zwick 1973 (Figs. 1-4) <i>Amphinemura coreana</i> Zwick 1973 — Zwick 1973:157. (description of male and female from People’s Republic of Korea); Zhiltzova 2003:179. (monograph, with the original figures); Teslenko &amp; Zhiltzova 2009:113. (key, with the original figures); Zwick 2010:76. (additional description of female). <b>Material examined.</b> PEOPLE’S REPUBLIC OF KOREA: Kanwon Province, Diamond Range, Hotel Go-song, 30.05.1970, leg. S{ndor Mahunka, Henrik Steinmann: holotype &amp;male;, 2&amp;male;, 4&amp;female; paratypes (HNHM); Kengi Province, Bagyon Mts., Kaesong, Bagyon Waterfall about 27km SW of the town, 07.06.1970: 1&amp;male; paratype (HNHM). KAZAKHSTAN: Almaty Province, Kapchagay, Ili River 20km NNW of the town, 550m, 30.08.1997, leg. Andr {s Orosz: 2&amp;male; (HNHM). <b>Morphology</b> (Figs. 1-4): Habitus of the Kazakh specimens agree with the Korean types, being large and dark nemourids. Their genital organs differ slightly in two aspects: The outer surface of the paraproct median lobe bear more spines than shown for the holotype (Zwick 1973: Fig. 3), and the epiproct has a shorter fold of the lateral arms above the denticulate crest of the ventral sclerite (Zwick 1973: Fig 4). Nevertheless, the paratypes also show some variability in these features, and the small differences of the Kazakh specimens should be regarded as individual variability more than a geographical race. <b>Geographical distribution and ecology</b> (Fig. 5): The species is known from throughout the Korean Peninsula and the southern part of the Russian Far East (Teslenko &amp; Zhiltzova 2009, Zwick 2010). It is not yet found in China, despite huge work on Chinese <i>Amphinemura</i> carried out since the description of this species (Du &amp; Wang 2007, Du, Wang &amp; Zhou 2007, Li &amp; Yang 2005, 2006, 2007, 2008a, 2008b, 2008c, 2008d, 2008e, Li, Yang &amp; Sivec 2005, Wang, Du, Sivec &amp; Li 2006, Wang, Zhang &amp; Zhu 2007, Wu 1973, Yang, Li &amp; Sivec 2005, Yang, Li &amp; Zhu 2004, Zhu &amp; Yang 2002, 2003). Due to its seeming absence in China, the occurrence in Kazakhstan was highly unexpected. <i>Amphinemura coreana</i> is regarded as an inhabitant of submontane rivers and streams (Zhiltzova 2003), its flight period extends from May to August (Zhiltzova 2003, Zwick 2010). Its Kazakh habitat is a large river with sandy bottom, flowing through a steppe vegetation on the foothills of the Tien San. The two males were found together with a <i>Nemoura</i> female (probably <i>N. lepnevae</i> Zhiltzova 1971). It is worth mentioning that the Trichoptera species collected during the same light trapping resulted in additional unexpected data of species hitherto known exclusively from the Far East (<i>Wormaldia niiensis</i>, <i>Plectrocnemia wui</i>, <i>Goera japonica</i>, <i>Lepidostoma itoae</i>); however, they were found together with typical Central Asian species (e.g. <i>Psychomyia usitata Potamyia straminea</i>) (Ol{h 2010).
