description: Hyleoglomeris coloratoides, new species   
(Figs. 36–39)  
 Material examined. Holotype: male (IEBR–Myr 658H) Vietnam, Ha Tinh Province, Huong Son District, Cau Treo, secondary forests, elevation of 800 m, 30 May 2004, coll. Nguyen A.D.   
Paratypes: 4 females (IEBR–Myr 658P) same data as for holotype.  
 Etymology. Named after the similarity to its congener, Hyleoglomeris colorata Golovatch et al., 2013 from the neighbouring province, Quang Binh.   
 Diagnosis. The species is differentiated by the following character combination: Thoracic shield with 10 superficial transverse striae. Telopods with a bilobed chevron-shaped syncoxial lobe. The new species is similar to its congeners, H. colorata, from Quang Binh Province in telopod shape, but differs in syncoxial lobe medially concave (vs roundly sub-trapeziform) and legs of leg-pair 17 with 4 podomeres (vs. 3 podomeres in H. colorata).   
 Description. Holotype male (IEBR–Myr 658H). Width of 2 nd tergum 5.3 mm, body length 6.5 mm.   
 Exoskeleton: Ethanol-preserved specimens light yellow, terga with traces of two paramedian transverse oval spots, and a medioposterior light yellow triangular spot (Fig. 36 A–D).   
 Head: Ocelli 6+1, lenses convex, black contrasting against yellow background of head. Tömösváry organs transverse oval, 2.0× wider than long. Antenna clavate. Antennomere 6 large, about 2.5× longer than wide. Antennal tip with four large, apical sensory cones. Tergites: Collum semicircular, with faint middle transverse oval spot, with two transverse striae. Second tergum with a narrow hyposchism, not reaching caudal margin, with 10 superficial transverse striae. Anal shield rounded, not concave medially. Legs: Leg-pair 17 strongly reduced, 4-segmented, coxa with a regular outer lobe. Leg-pair 17 (Figs. 37A, 38A) in males with a setiferous tubercle distomesally on each side of the syncoxite, with large syncoxial lobe, podomere 1 with small distomesal setiferous knob. Leg-pair 18 less reduced (Figs. 37B, 38B), legs similar to leg pair 17, but podomere 3 strongly reduced, very short, and syncoxial lobe small.   
 Telopods (Figs. 37C, D, 38C, D, 39) with a bilobed chevron-shaped syncoxial lobe, sparsely setose, two horns paramedially (Fig. 39D), each directed ventrad, longer than syncoxial lobe. Prefemur and femur with trichosteles. Femur with a straight, large, triangular, distal process. Tibia with stout, broadened process (tp) near base (Figs. 37C, 38D). Tarsus S-shaped, acuminate apically (Fig. 39A).   
 Variation. Width of tergum 2 ca. 5.5–6.3 mm (female); length ca. 8.5–11.3 mm (female). Holotype ca. 6.5 mm long, width ca. 5.3 mm at tergum 2.
