Abstract: Paralycus subiasi Oshima & Shimano sp. nov. [Japanese name: Koke-oboro-dani] (Figures 1–3) Materials Examined. Holotype: adult female, Japan, Torigajo-catsle, Yamanouchi, Touon City, Ehime Prefecture, 28-VI-2004, coll. M. Shiba from the moss on the bark of L yonia ovalifolia var. elliptica (Siebold & Zucc.) Hand. - Mazz. Type deposition. Holotype was deposited in the Collection of Arachnida, Department of Zoology, National Museum of Nature and Science, Tokyo (NSMT) [collection number: NSMT-Ac 14773]. Diagnosis. Female Rostral seta long, reaching half the length of chelicera. Bases of lamellar setae slightly adjacent. Cheliceral seta cha shorter than half length of chelicera. Gastronotal setae d 1 and e 1 not reaching bases of next row of setae; c 2 reaching base of c p seta; f 1 and h 1 reaching bases of next row of setae. Epimeral seta 2a relatively short, not exceeding base of 1a. Epimeral seta 4a absent. Four pairs of genital setae present; distance g 3 – g 4 <g 1 – g 2 <g 2 – g 3. Leg trochanteral formula 0-0-0-0. Four setae on genu I; d, (l) and v′, genu II with two setae (l). Solenidion ω of tarsus I not expanding in middle; solenidion φ of tibia III short. Description. Female Measurements. Idiosomal length 199, width 66. Integument. Colorless, elongate and weakly sclerotized. Prodorsal shield, legs and coxae smooth. Dorsal side (except segment H and P), ventral side, chelicerae (basal part), and ovipositor finely striated. Gnathosoma. Subcapitulum (28 × 24) with three pairs of filiform, smooth setae (a 11; m 12; h 9) and two pairs of filiform and smooth adoral setae (2, 4). Palp (22) simple, with four free segments; femur and genu separated by incomplete suture. Palpal setae formula: 0-1-0-1-9+ ω, including four eupathidia (sul, acm, ul; sul, acm, ul′ with expanded tips); inf absent. Postpalpal seta (ep 2) blunt. Chelicera (22) with two filiform and smooth setae (cha 4; chb 7); cha shorter than half of cheliceral length. Pharyngeal cupola long, reaching level of bs. Prodorsum. Mid-dorsal region covered with shield-shaped plate, bearing two pairs of filiform and smooth setae (ro 14; le 21); ro reaching half the length of chelicera. Bases of setae le slightly adjacent. In dorsolateral region, three pairs of filiform setae (in, exa, exp) and one pair of clavate bothridial setae (bs) present; in (32), exa (13), exp (3) and bs (15 × 7) smooth. Notogaster. Three transverse scissures divide notogaster into four regions; tf 1 and tf 2 faint while tf 3 conspicuous. Sixteen pairs of notogastral setae present. Four pairs of setae in region of segment C: c 1 (10), c 2 (16), c 3 (18) and c p (26). Four pairs of setae in region of segment DE: d 1 (14), d 2 (17), e 1 (22) and e 2 (23). Two pairs of setae in region of segment F: f 1 (35) and f 2 (30). Segments H and P fused with six pairs of setae: h 1 (30), h 2 (30), h 3 (21), p 1 (21), p 2 (25) and p 3 (10). All gastronotal setae filiform and smooth, not expanded at their bases. Seta c 2 reaching base of c p; d 1 not reaching base of e 1; e 1 not reaching base of f 1; f 1 reaching base of h 1; h 1 reaching base of p 1. Seta p 2 longer than p 1. Notogastral cupules absent. Epimeral and podosomal regions. Epimeral setation 3-2-3-2; 1а (7), 1b (10), 1с (7), 2a (13), 2b (12), 3a (4), 3b (11), 3c (6), 4b (8) and 4c (3) filiform and smooth. Seta 2a not reaching base of 1a. Bases of 3a close to each other. One pair of triangular supracoxal setae (el 2) with rounded tips. Anogenital region. Four pairs of genital setae: g 1 (7), g 2 (4), g 3 (9) and g 4 (8). Distance g 3 – g 4 <g 1 – g 2
