Ljania orientalis Tuzovskij, 2012

( Figs. 6 C­D)

New records: South Korea: CR4 Gangwon Province, Seoraksan NP, stream near Temple , 38º10.399' N, 128º29.050' E, 196 m asl., 8.x.2012, Pešić & Karanović 0/1/0; CR9 Jeollabuk Province, Ne myeon Mt, Naebyeansan NP, stream near Naebyeansan Info Center, 35°38'25.623"N, 126°34'53.1438"E, 10.x.2012, Pešić & Choi 1/1/0 (1/0/0 mounted) .

Remarks: This species, recently described from the Primory Territory in the Russian Far East, can be distinguished from L. japonica Imamura, 1956 (described after a single male from Japan, Imamura 1956) by the posterior pair of setae on dorsal shield associated with glandularia, the excretory pore located dorsally, the complete median suture line Cx­II/III, P­3 dorsoproximal setae considerably shorter than dorsodistal setae, and presence of a transverse suture line between the middle of the lateral margin of the Cx­IV and the lateral margin of the ventral shield ( Tuzovskij 2012).

Kim and Chung (1996) reported and illustrated L. japonica from Korea. As their illustrations ( Kim and Chung 1996: Figs. 12, 13A­B) show a general conformity with L. orientalis in all abovementioned characters, it is very likely that the specimens attributed to L. japonica refers to L. orientalis .

Habitat: Streams.

Distribution: Russia (Primory Territory), Korea.
