Figs 7–14.
Material examined
Holotype: 1 male (ChNU) from Buan­gun, Jeollabuk­do, South Korea, collected 18 May 1991 by K.­Y. Lim. Paratypes: 1 male, 1female (ChNU), 1 male (ZMUM), same locality as for holotype, collected 18 May 1991 by K.­Y. Lim.
Diagnosis
Differs from congeners mainly by the syncoxital lobe of the telopods being relatively large, subovoid and stretched horizontally, by the high telopod syncoxital lateral horn supplied with a subapical setoid, as well as by the coloration pattern of a white, wide, unbroken, widened laterad belt on the thoracic shield and of pair of marbled brown oblong lateral spots on each following tergite.
Etymology
The specific epithet refers to the type locality.
Description
Male. Length ca.8.0 mm, width 3.5–3.7 mm. Background coloration of head blackbrown with several small yellowish­white spots above level of antennal sockets; clypeus and labrum yellowish­white. Antennae brown; antennomeres 1 and 2 light brown. Tömösváry’s organs white. Ocelli black. Dorsum black­brown. Collum with a marbled brown central pattern (Fig. 7). Thoracic shield with a white, wide, unbroken transverse belt occupying its anterior portion and widening laterad (Fig. 8). Each following tergite with pair of marbled brown oblong lateral spots and a translucid caudal margin. Hidden anterior portion of the tergite marbled brown. Pigidium black­brown with a white caudal margin and five indistinct, small, subtriangular central spots near somite 11. Some specimens with very weak traces of an axial stripe on posterior 3–4 somites. Venter white. Distal parts of legs brownish. Telopods white.
Ocelli convex, gradually reducing in size toward Tömösváry’s organ. Holotype with 9+1 ocelli and paratypes with 8+1 or 9+1 ocelli on each 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 relatively narrow hyposchism reaching but not protruding beyond hind tergal margin, with 9 delicate striae of which only four entirely crossing dorsum (Fig. 9). 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. 10) with high, regularly rounded outer coxal lobes, telopodite 4­ segmented. Leg pair 18 (Fig. 11) with a lancet­shaped syncoxital notch, telopodite 4­ segmented, basal segment with rare papillae laterally.
Telopods (Fig. 12) massive; central lobe of syncoxite relatively large, subovoid, stretched horizontally, covered with microscopic hairs, very weakly curved anteriad. Surface of syncoxital lobe smooth frontally and shagreen caudally. Syncoxital lateral horns high, slender, setose, directed somewhat caudoventrad, each with a setoid subapically (Fig. 13). Prefemur micropapillate laterally and mesally. Prefemur with a long inner setose finger crowned with a long flagelloid. Femur with a shorter anteromesal setose finger also crowned by a flagelloid, posteriorly with a large inner outgrowth apically bearing a membranous sack curved forward. A small papillate field at base of femoral anteromesal finger. Caudomedial outgrowth of femur relatively narrow at base (Fig. 14). Tibia with a long anteromedial seta, posteriorly with a curved, dentiform, medial outgrowth. 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 8.0 mm, width 4.0 mm. Ocelli 9+1 on right side of head, 8+1 on left side of head. Antennae reduced, deformed. Pigidium regularly margined.
Remarks
A restudy of the above material from South Korea, which was misidentified as Hyleoglomeris emarginata Golovatch, 1981 by Mikhaljova & Lim (2000) proves that it actually belongs to H. buana sp. n. Thus, at present only six species of Hyleoglomeris (including new species) definitely occur in Korea.
This new species seems to be particularly closely related to H. koreana Golovatch, 1978 described from the environs of Kannyn, South Korea, but differs by the shape of the caudomedial outgrowth of the telopod femur, by the structure of syncoxital lobe and lateral horns of the telopods, as well as by arrangement of thoracic striae and body coloration.
