Figs 22–29 .

Material examined

Holotype: 1 male (ChNU) from Jeongok, Yeonchon­gun, Gyeongi­do, South Korea, collected 17 May 1991 by K.­Y. Lim. Parartype: 1 female (ChNU), same locality as for holotype, collected 17 May 1991 by K.­Y. Lim.

Diagnosis

Differs from congeners mainly by the thoracic coloration pattern of the anterior whiteyellowish transverse band and pair of marbled brown oblong lateral spots, combined with the oval, vertically stretched syncoxital lobe of the telopods, the very high telopod syncoxital horns without apical modifications, the strongly curved anteriad caudotibial outgrowths of the telopods, the irregularly rounded edge of the small coxal lobe of the male leg pair 17.

Description

Male. Length 5.5 mm, width 2.9 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 dark­brown; antennal sockets yellow. Dorsum brown. Collum with a large oval marbled brown central spot ( Fig. 22 ). Thoracic shield with a white­yellowish transverse band occupying its anterior striate portion; pair of marbled brown oblong spots placed laterally ( Fig. 23 ). Each following tergite with pair of marbled brown oblong lateral spots and a translucid caudal margin ( Fig. 24 ). Hidden anterior portion of tergite marbled brown. Pigidium brown with lucid caudal margin and without any pattern. Venter, legs and 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 9 delicate striae of which only three entirely crossing dorsum, with a relatively narrow hyposchism reaching but not protruding beyond caudal tergal margin. Anterolateral corners of hyposchism lobe­shaped and protruding anteriad ( Fig. 23 ). Length of stria varied. A broad hollow occupying 4 striae placed between schism and hyposchism laterally. As usual, anterior border of thoracic shield with one stria concealed under caudal margin of collum. Pigidium delicately sinuate medially at caudal margin.

Leg pair 17 ( Fig. 25 ) with small and irregularly rounded outer coxal lobes, telopodite 4­segmented with three claws apically. Leg pair 18 ( Fig. 26 ) with a lancet­shaped syncoxital notch; telopodite 4­segmented.

Telopods ( Fig. 27 ) with a relatively small, thick, oval, vertically stretched, microsetose central syncoxital lobe. Surface of syncoxital lobe with a low smooth prominence frontally and shagreen shallow cavity caudally. Syncoxital lateral horns very high, slender, covered with setae proximally. Distal portion of syncoxital horn without visible modifications, excluding tiny wrinkles ( Fig. 28 ). 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 with a flagelloid and posteriorly with a large inner outgrowth apically bearing a membranous sack curved forward. Caudomedial outgrowth of femur wide at base ( Fig. 29 ). Tibia with a long anteromedial seta, posteriorly with medial outgrowth strongly curved anteriad. Caudomedial outgrowth of tibia bearing a micropapillate tubercle. Tarsus with a strongly curved caudad distal part and a subapical seta.

Female. Length 7.0 mm, width 3.0 mm. Pigidium regularly margined. Ocelli 6+1 on each side of head. Thoracic shield with 10 delicate striae on left side and 11 such striae on right side, of which only three entirely crossing dorsum. Length of the striae varied. A broad hollow occupying 4 striae placed between schism and hyposchism.

Remarks

A restudy of the above material proves that Mikhaljova & Lim (2000) misidentified Hyleoglomeris confragosa sp. n. specimens (male and female) from Gyeongi­do, South Korea as belonging to H. koreana .
