Figs 30–37 .

Material examined

Holotype: 1 male (ChNU), from Gyorye, Jeju­do, South Korea, collected 3 June1992 by K.­Y. Lim. Paratypes: 4 males, 3 females (ChNU), 1 male, 1 female ( ZMUM), same locality as for holotype, collected 3 June 1992 by K.­Y. Lim.

Diagnosis

Differs from congeners mainly by the shagreen striate portion of the thoracic shield and the thoracic coloration pattern of an anterior white­yellowish narrow transverse band and pair of marbled brown oblong lateral spots, combined with the subovoid syncoxital lobe of the telopods, the very high telopod syncoxital horn with subapical setigerous processes and the small coxal lobe of male leg pair 17.

Etymology

The specific epithet refers to the shagreen striate portion of the thoracic shield.

Description

Male. Length 4.5–5.5 mm, width 2.5–3.0 mm. Background coloration of head brown with several small light spots between and above antennal sockets; clypeus, labrum and Tömösváry’s organs yellow. Ocelli black. Antennae brown; antennomeres 1 and 2 light brown. Dorsum brown. Collum with a large oval marbled brown central spot ( Fig. 30 ). Thoracic shield with a white­yellowish narrow transverse band; pair of marbled brown oblong spots placed laterally ( Fig. 31 ). Each following tergite with pair of marbled brown lateral spots and a translucid caudal margin ( Fig. 32 ). Hidden anterior portion of tergite brown. Pigidium brown with a lucid caudal margin but without any pattern. Venter yellowish. Legs yellowish with light brown distal and dorsal portions. Telopods yellowish.

Ocelli convex, 6+1 on each side of head. Antennomere 6 about 2.0 time longer than wide. Dorsum smooth. Collum semicircular, with two transverse striae. Thoracic shield with 9­10 delicate striae, of which only three entirely crossing dorsum; lateral striate portion shagreen. Length of the striae varied. As usual, anterior border of thoracic shield with one stria concealed under caudal margin of collum. Hyposchism relatively narrow, reaching but not protruding beyond caudal tergal margin. Anterolateral corners of hyposchism rounded and somewhat protruding anteriad ( Fig. 31 ). A broad hollow occupying 4–5 striae placed between schism and hyposchism laterally. Pigidium very indistinctly sinuate medially at caudal margin.

Leg pair 17 ( Fig. 33 ) with small and irregularly rounded outer coxal lobes, telopodite 4­segmented with three or four claws apically. Leg pair 18 ( Fig. 34 ) with a lancet­shaped syncoxital notch; telopodite 4­segmented.

Telopods with a small thick subovoid microsetose central syncoxital lobe having a low smooth prominence frontally and shagreen shallow cavity caudally ( Fig. 35 ). Syncoxital lateral horns very high, slender, directed caudad, covered with setae proximally. Distal portion of the syncoxite horn with subapical curved setigerous processes caudally ( Fig. 36 ). Prefemur micropapillate laterally and somewhat mesally, with a long inner setose finger crowned with a long flagelloid. Femur with a shorter anteromesal setose finger also crowned by a flagelloid and posteriorly with a large inner outgrowth apically bearing a membranous sack curved forward. Caudomedial outgrowth of femur narrow at base ( Fig. 37 ). Tibia with a long anteromedial seta, posteriorly with a medial outgrowth strongly curved anteriad. Caudomedial outgrowth of tibia with a micropapillate tubercle at base. Tarsus with strongly curved caudad distal part and a subapical seta.

Female. Length 6.0–7.0 mm, width 3.0– 3.5 mm. Pigidium regularly margined. Ocelli 6+1 on each side of head. Thoracic shield with 9–10 delicate striae, of which only three entirely crossing dorsum; lateral striate portion shagreen. Length of the striae varied. A broad hollow occupying 4–5 striae placed between schism and hyposchism laterally.
