Material examined

Holotype: 1 male (ChNU) from Jeongok, Yeonchon­gun, Gyeongi­do, South Korea, collected 17 May 1991 by K.­Y. Lim.

Diagnosis

Differs from congeners mainly by the coloration pattern of dorsum with pair of indistinct, weakly marbled black­brown oval lateral spots on each tergite as well as with a yellowish, wide transverse band interrupted centrally on the thoracic shield, combined with the syncoxital lobe of the telopods being relatively large and rounded apically, the telopod syncoxital horns devoid of apical modifications, the caudotibial outgrowths of the telopods strongly curved anteriad, the shape of the syncoxital notch (as vertical section of a crater) of male leg pair 18.

Description

Male. Length 9.0 mm, width 4.5 mm. Background coloration of head black­brown; clypeus, labrum and Tömösvary’s organs light brown. Ocelli black. Antennae brown with black­brown distal parts. Dorsum black­brown. Collum with a large vague, oval marbled brown central spot ( Fig. 15 ). Thoracic shield with a yellowish wide transverse band occupying its anterior portion and somewhat widening laterad; the band interrupted centrally as a narrow stripe; pair of indistinct weakly marbled black­brown oval spots placed laterally ( Fig. 16 ). Each following tergite with pair of relatively indistinct weakly marbled black­brown oval lateral spots and a translucid caudal margin ( Fig. 17 ). Hidden anterior portion of tergite weakly marbled brown or black­brown. Pigidium black­brown, without any pattern. Venter yellowish, with brownish sternites. Distal parts of legs brownish, growing increasingly dark distad. Leg coxae brown apically. Coxal lobes of leg pair 17 brownish. Telopods brownish laterally.

Ocelli convex, 9+1 on each side of head. Antennomere 6 about 2.1–2.2 times longer than wide. Dorsum smooth. Collum semicircular, with two transverse striae. Thoracic shield with a relatively narrow hyposchism reaching but not protruding beyond hind tergal margin, with 7 delicate striae of which only three entirely crossing dorsum. Length of the striae varied. 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. 18 ) with high and regularly rounded outer coxal lobes, telopodite 4­ segmented with three claws apically. Leg pair 18 ( Fig. 19 ) with syncoxital notch as vertical section of a crater, telopodite 4­segmented.

Telopods ( Fig. 20 ) with a relatively large subovoid, horizontally stretched, central syncoxital lobe covered with microscopic hairs, curved anteriad. Surface of syncoxital lobe smooth frontally and shagreen caudally. Syncoxital lateral horns high, slender, directed strongly caudoventrad, covered with setae laterally but not mesally. Distal portion of syncoxital horns without modifications. Prefemur micropapillate laterally and 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. 21 ). Tibia with a long anteromedial seta, posteriorly with medial outgrowth strongly curved anteriad. Caudomedial outgrowth of tibia with a weakly micropapillate tubercle at base. Tarsus with a strongly curved caudad distal part and a subapical seta.

Female unknown.

Remarks

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