SOUTH KOREA: CR16 Gyeongsangbuk Province, Juwangsan NP, Woroe-ri, Cheong song-eup, Dalgikpo, waterfall, 36°26.499'N, 129°08.114'E, 23.v.2013 Pešić & Karanović 0/1/0 (mounted).

Morphology.

Idiosoma L 1800, coxae and genital field: Fig. 2A, Cx-I+II total L 144-146, W 111-125, Cx-III+IV lateral L 144-145; number of coxal setae: Cx-I, 3, Cx-II, 0, Cx-III, 1, Cx-IV, 1; genital field with three pairs of Ac and three setae on a transparent sclerotized strip on each side; gonopore L 106; Ac-1 L 29, L/W 1.28, Ac-2 L 32, L/W 1.5, Ac-3 L 30, L/W 1.2.

Gnathosoma vL 189, chelicera (Fig. 2C) total L 223, H 39, L/H ratio 5.8, basal segment L 150, claw L 60, L basal segment/claw ratio 2.5. Palp: dL/H, dL/H ratio: P-2, 63/41.5, 1.5; P-3, 56/45, 1.26; P-4, 94/27, 3.5; P-5, 25/12, 2.1; L P-2/P-4 ratio 0.67; palp setation as given in Fig. 2B.

Legs: setation as given in Fig. 2 E–H; dorsal margin of I-L-6 and II-L-6 strongly concave (Fig. 2 E–F); dL of I-L-3-6: 95, 118, 123, 123; II-L-3-6: 92, 111, 120, 122; III-L-3-6: 71, 191, 109, 121; IV-L-3-6: 108, 129, 122, 123.

Remarks.

With regard to similar setation of coxae, P-5 without a flagelar seta and dorsal margin of the tarsus of I-L and II-L strongly concave, the new species resembles Wandesia rara Tuzovskij, 1990 a species described from the Primory Territory in the Russian Far East on the basis of a single deutonymph ( Tuzovskij 1990). The difference is found in more elongated Ac (L/W 2.0, calculated from figure 38-1, of Tuzovskij (1990)) in the deutonymph of Wandesia rara . Thus, our assignment of specimen from Korea is tentative. Only with more material in the future, and finding of a adults from the locus typicus it will be possible to decide whether the specimen from Korea is conspecific with Wandesia rara or a species new for science.

Distribution.

Far East of Russia (Primory Territory - Tuzovskij 1990). New for the fauna of Korea.
