Figs 1–6 .

Material examined

Holotype: 1 male (ChNU), from Goyang, Gyeonggi­do, South Korea, collected 17 May 1991 by K.­Y. Lim. Paratypes: 1 male, 2 females (ChNU), same locality as for holotype, collected 17 May 1991 by K.­Y. Lim.

Diagnosis. Differs from congeners mainly by the monochrome coloration without any pattern, combined with the ovoid syncoxital lobe of the telopods and syncoxital lateral horn crowned with wrinkles and a subapical setoid.

Etymology

The specific epithet refers to the monochrome coloration of the body.

Description

Male. Length 7.5–8.0 mm, width 4.0– 4.5 mm. Body coloration in alcohol light tan, without any pattern of spots and stripes. Clypeus light tan. Antennae light tan with distal antennomeres brownish tan. Ocelli tan. Tömösváry’s organ light tan. Venter somewhat lighter than dorsum. Legs light tan.

Ocelli convex. Holotype with 8+1 ocelli on each side of head. Paratype with 7+1 ocelli on right side and 8+1 ocelli on left side of head. Antennomere 6 about 2.1–2.2 times longer than wide. Dorsum smooth. Collum with two transverse striae. Thoracic shield with a narrow hyposchism reaching but not protruding beyond hind tergal contour, with 8 delicate striae, of which only four entirely crossing dorsum ( Fig. 1 ). Some of the striae with branch. Length of striae varied. As usual, anterior border of the thoracic shield with one stria concealed under caudal margin of collum. Pigidium delicately sinuate medially at caudal margin.

Leg pair 17 ( Fig. 2 ) with high, regularly rounded, outer coxal lobes, telopodite 4–jointed. Leg pair 18 ( Fig. 3 ) with a lancet­shaped syncoxital notch, telopodite 4­jointed, basal segment with sparsely papillate laterally.

Telopods ( Fig. 4 ) massive; central lobe of syncoxite rather large, ovoid, microsetose, with a low and smooth prominence frontally and a shagreen shallow cavity caudally. Syncoxital lateral horns high, slender, setose, directed caudad, each crowned with wrinkles and a subapical setoid ( Fig. 5 ). Both prefemur and femur micropapillate laterally and mesally. Prefemur with a long, inner, setose finger crowned with a long flagelloid. Femur with a similar but 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 relatively narrow at base ( Fig. 6 ). Tibia with a long anteromedial seta, with a curved dentiform medial outgrowth posteriorly.

Caudomedial outgrowth of tibia with a weakly micropapillate tubercle at base. Tarsus with a somewhat curved caudad distal part and a strong subapical seta.

Female. Length 9.5–10.0 mm, width 5.0– 5.5 mm. Ocelli 7+1 to 8+1. Antennomere 6 about 2.2–2.3 times longer than wide. Pigidium very slightly sinuate medially at caudal margin. One paratype with hyposchism somewhat protruding beyond hind tergal contour.
