Material examined. Holotype female, dissected and slide mounted, Korea, CR10 Jeollabuk Province, Ne myeon Mt, stream near Silsung temple, 1.7 km to Jiksopolpol falls, Naebyeansan NP, 0.6 km from Naebyeansan Info Center, 35°64'65.978"N, 126°58'62.285"E, 10.x.2012, Pešić & Choi. Paratype: one female, same locality and data as holotype.
Diagnosis (Male unknown). Idiosoma> 800; dorsal shield with colour pattern as illustrated in Fig. 5C. Cx­II and ­III with a spine­like seta; suture line Cx­II/III undulating, forming a bay embracing Cxgl­4, located anterior to IV­L insertions; L1 anteromedially to L2.
Description
Female – Colour pale yellow, dorsal shield with colour pattern as illustrated in Fig. 5C. Dorsal shield L 813, W 597, L/W ratio 1.36. Coxal field: Cx­II and Cx­III each with two spine­like setae; gnathosomal bay L 138; suture lines of Cx­II/III and Cx­III/IV continuous, reaching the median line; Cx­II/III median fusion point between Cx­III/IV median fusion point and Cx­I/II median fusion point; suture line Cx­II/III undulating, forming a bay embracing Cxgl­4, located anterior to IV­L insertions (Fig. 4B). Distance Cxgl4­Cxgl4 142, Cxgl 2­Cxgl 2 197; distance between IV­L­insertions 250. L1 anteromedially to L2 Genital field: Acetabular plate L/W 94/98­100, each plate with 37­38 acetabula.
Palp (Fig. 4C): palp total L 325­326, dL/H, d/H ratio: P­1, 40/39, 1.02; P­2, 81/48, 1.7; P­3, 57/43, 1.32; P­4, 106/33, 3.19; P­5, 41­42/18, 2.3; L ratio P­2/P­4 0.76; P­4 with 2 setae in the distal half of ventral margin and 5­6 dorsodistal setae. Gnathosoma vL 134, with apodemes 207; chelicera total L 221, basal segment L 157, claw L 66.
Leg swimming setae numbers: II­L­5, 4; III­L­5, 4­7; IV­L­5, 6­7. dL of I­L­2­6: 49, 65, 80, 91, 104; dL of II­L­2­6: 55, 74, 86, 104, 102; dL of III­L­2­6: 59, 76, 92, 103, 99; dL of IV­L: 126, 52, 93, 111, 122, 97.
Male – unknown.
Etymology. Named after Ksenia Semenchenko (Vladivostok, Russia), for her contribution to the taxonomy of water mites.
Remarks. Due to the similar configuration of coxal suture lines and shifting of Cxgl­4 anterior to IV­L insertions, the new species is most similar to A. vanimoensis Wiles, 1992 and A. papuaensis Smit, 2013, from Papua, New Guinea, both only known in the female sex (see Wiles 1992 and Smit 2013, respectively). The new species can be distinguished from the abovementioned species by the different colour pattern (dorsal shield posteriorly with a rose tinge in A. papuaensis, a blue band across the middle of the dorsal shield in A. vanimoensis) and by having a spine­like seta on Cx­II and Cx­III. Albia papuaensis (in parentheses data taken from Smit 2013), is similar in a broader idiosoma (L/W ratio 1.32), and L2 lying anteromedially to L1, but differs in minor idiosoma and palp dimensions (L idiosoma 664, P­2, 60; P­4, 62). A. vanimoensis differs in a more slender idiosoma (L/W ratio 1.59) and L2 lying anterior, but both median (Wiles 1992).
Habitat. A small sandy/bouldary pool near the main stream, shaded by riparian vegetation (Fig. 11).
Distribution. South Korea; known only from the type locality.
