Skleroprotopus chollus sp. n.

( Figs 6–13 )

1 m (holotype), 5 mm, 6 ff, 2 juvs (paratypes) – South Korea, South Cholla Prov. , Mt. Paekun-san, at the vicinity of the pass towards to the Mts Chiri-san , 800–860 m, ca. 3 km NNW of Nonshil , under bark, stones and trunks, No. 1662., 31.Oct.1993., leg. PEREGOVITS L. & RONKAY L .

Male holotype, 3 mm, 4 ff, 2 juvs paratypes are deposited in the HNHM, 1 m , 1 f paratypes in ZMUM, 1 m , 1 f paratypes in IBSV .

Etymology: The specific epithet refers to the locus typicus (South Cholla Province).

Description: Male. Body 15–28 mm long, 0.8–0.9 mm in diameter. Body segments without telson 48(–1) (holotype), 45(–2) (two specimens), 47(–2), 54(–1), 61(–1).

Coloration: Prozona dark brown with a light anterior edge. Metazona dark brown with a light posterior edge. Transverse suture between pro- and metazona light. Each ring with a light spot around ozopore. Anterior part of body with metazona marble brown dorsally. Antennae brown. Legs light brown, eyes black.

Body subcylindrical, smooth. About 40 ocelli in a subtriangular eyepatch on each side of head. Vertigial setae absent. Supralabral setae 2+2, labral ones 10+10. Mandibular stipes subtriangular with two small tubercles on lower border. Gnathochilarium with three distal setae on stipes and six setae on each lamella linguales; stretched promentum with low tubercle at base and apical process ( Fig. 6 ). Antennae ( Fig. 7 ) relatively short, clavate, 5th and 6th antennomeres with a distal corolla of tiny bacilli, ventrally these corolla incomplete. Prozona with uneven striations directed obliquely laterally and increasingly transversely dorsad. Metazona with distinct striae below ozopores. Collum with 6–7 striae. Ozopores small, beginning from somite 6, lying behind and far set off from suture dividing pro- and metazona. Telson with some setae along hind margin, without tail. Each anal valve and an oval subanal scale with two setae.

view. Scales in mm

Legs moderately long, slender, claws long with an additional claw at base. Legpair 1 ( Fig. 8 ) relatively enlarged, modified, curved forward. Penes ( Fig. 9 ) elongated, with three short setae apically. Leg-pair 7 ( Fig. 10 ) with the remnant of telopodite bearing long setae apically ( Fig. 11 ) and a small coxal process covering with setae mesally and apically.

Gonopods: Anterior gonopods ( Fig. 12 ) with 1-segmented telopodites bearing out some setae apically. Coxal process flat, lateral edge curved caudally. Parabasal long flagella with thin spines apically. Posterior gonopods ( Fig. 13 ) with very low sublateral tubercle bearing tiny setae. Distocoxal portion biramous, posterior branch setose, anterior one bare with pointed apex.

Female. Body 21–23 mm long, 0.8–1.0 mm in diameter. About 45 ocelli. Body segments without telson up to 53(–1) (paratype from IBSV). Mandibular stipes oval without tubercles on lower bor- der. Promentum of gnathochilarium without tubercle at base and apical process. Vulva not dissected for examination .

Remarks: Legpair 7 of one of male paratypes is devoid of left telopodite remnant while right such remnant is expressed.
