Diagnosis: Differs from congeners mainly in the unusually strongly sinuate tarsi and the bifid caudofemoral processes of the telopods (Figs 21, 22, 30 and 31), as well as by the colour pattern which is often identical to that of Mauriesia splendida.
Description: Length of non-stretched but unrolled specimens ca 6.0–6.5 (male) or 6.5–9.0 mm (female), width 2.3–2.7 (male) or 2.8–4.0 mm (female), respectively. Holotype ca 6.0 mm long and 2.7 mm wide. General coloration light brown to blackish with contrastingly whitish to yellow or red-yellow spots (Figs 15– 24). Head and antennae marbled castaneous brown to black-brown. Thoracic shield with a large, dark, central spot (almost) reaching fore margin and divided caudad by a light spot, also with large, dark, lateral spot on each side. Following terga in front of pygidium with a light, wide, complete axial line and 1+1 light, large, marbled, oblong, lateral spots. Pygidium mostly light, with a small, or more elongate, longitudinal, dark spot stretching down from base caudad; laterobasal part more or less narrowly infuscate. Venter and legs light yellow to red-brown to marbled brown.
Head with a densely setose labrum (Figs 17 and 20). Gnathochilarium with 2+2 palps of subequal length. Ocellaria blackish, ocelli 6(7, 8)+1, lenses very convex, translucent. Antennae with four large apical cones, segment 6 ca 2.2–2.3 times as long as high. Organ of Tőmősváry oblong-oval, elongate, ca 1.4–1.5 times as long as broad.
Collum as usual, with two transverse striae.
Thoracic shield (Figs 15, 18 and 23) with a small hyposchism field not projecting caudad beyond tergal contour. Striae 8–10, mostly superficial, only first three above schism more evidently impressed: 3–4 lying above schism, one level to schism, remaining 3–5 below schism, with 3–6 (different) complete, crossing the dorsum. Following terga in front of pygidium extremely faintly bisinuate at caudal edge and with two striae starting above lateral edge (Fig. 5). Male pygidium very faintly truncate medially at caudal edge.
Male leg 17 (Fig. 28) particularly strongly reduced, with a low, very small, rounded coxal lobe and a 4- segmented telopodite. Male leg 18 (Figs 22 and 29) less strongly reduced, with a broadly ogival syncoxital notch and a 4-segmented telopodite.
Telopod (Figs 21, 22, 30 and 31) usual, medium-sized, with a broad, rounded to faintly concave, subtrapeziform syncoxital lobe flanked by especially high, slender, setose, distad attenuating horns; latter’s tip bulbous and shaggy. Femur with a conspicuously bifurcate caudomedial process. Tibia on caudal face with a small papillate tubercle at base of caudomedial process. Tarsus unusually sinuate, twisted, very narrowly rounded at apex.
Name: To emphasize the unusually strongly twisted telopod tarsus.
Remarks: This species seems to be rather widespread in and endemic to the central parts of Taiwan proper (Map). Korsós (2004) referred the female from Meifeng to a Hyleoglomeris sp.
