(Figs 8, 9, 12, 13, 25, 26, 33, 107–118, 123)
Type material. HOLOΤYΡΕ: 1 ♁, ‘[Taiwan] Dahanshan (Mt.). | Alt. ca. 1,200 m, Chunrih | Township, Pingtung County | DZAEḆĦHṞ†Oiffi | 28. V. 2015, W. C. Liao leg.’ (EUMJ). PΑRΑΤYΡΕ: 1 ♀, ‘FORMOSA | TAIWAN | 1968.....1971’, unknown collector. (EUMJ).
Description. Male (Figs 8, 12). Head, pronotum, elytra yellowish brown; antennae and legs brownish black.
Antennae (Fig. 25) longer than total length of head and pronotum combined, antennomeres III to X acutely serrate; XI fusiform, twice as long as X.
Pronotum smooth at apex; postcoxal projections short; prosternal process long, completely separating postcoxal projections. Elytra with rows of deep, large, asetigerous punctures in basal 5/6; apical margins not indented. Mesoventrite with evenly and densely arranged setigerous punctures. Metaventral anterior process tapered and as wide as mesoventral posterior process. Metendosternite (Fig. 107) with short furcal laminae; process extending anteriorly, tapered; furcal arms almost straight, extending anterolaterally.
Protibiae (Fig. 33) gently widening from base to apex., weakly curved. Tibial spur formula 0–0–0.
Apical margin of abdominal ventrite V emarginated broadly. Apical margin of pygidium (Fig. 108) rounded posteriorly; struts short. Apical margin of ventrite VI (Fig. 109) weakly emarginated. Spicular fork (Fig. 110) with intraspicular plate, which is 1/3 of spicular fork.
CM (Figs 113–115) bearing fine spines. Tegmen shorter than phallus; phallobase incised dorsally; phallobasic struts reaching phallobasic apodeme, which is 3/4 as long as tegmen. Phallus flattened, divaricated in apical 1/3, rounded at apex.
Female. Similar to male (Fig. 9), but EyD/EyW 2.30; antennae (Fig. 26) weakly serrate; elytra pointed posteriorly at apex; central portion of metaventrite with pair of bundles of elongate setae-like trichobothria; apical margin of abdominal ventrite V truncated broadly and deeply in middle.
Pygidium (Fig. 111) rounded posteriorly, with struts short. Ventrite VI (Fig. 112) rounded posteriorly, with apodeme 2/3 as long as ventrite VI.
Spermatheca membranous; Sc lacking. CPr (Figs 116–118) distally trifurcate; central process large; dorsolateral and ventrolateral processes relatively short.
Measurements and ratios. Male (n Y 1): BL: 10.18 mm; PL: 2.18 mm; PWA: 1.28 mm; PWM: 0.48 mm; PWB: 1.03 mm; EL: 8.00 mm; EW: 1.83 mm; EyD: 0.35 mm; EyW: 0.63 mm; EL/PL: 3.68; EW/PWA: 1.43; EW/PWM: 3.84; EW/PWB: 1.78; PWA/PWB: 1.24; PWA/PWM: 2.68; PWB/PWM: 2.16; EyD/EyW: 0.56. Female (n Y 1): BL: 13.4 mm; PL: 2.18 mm; PWA: 1.28 mm; PWM: 0.98 mm; PWB: 1.43 mm; EL: 10.9 mm; EW: 2.20 mm; EyD: 1.15 mm; EyW: 0.50 mm; EL/PL: 4.36; EW/PWA: 1.21; EW/ PWM: 2.26; EW/PWB: 1.54; PWA/PWB: 1.28; PWA/ PWM: 1.87; PWB/PWM: 1.46; EyD/EyW: 2.30.
Differential diagnosis. This new species is similar to C. terminalis, but it is distinguishable by the following characters: EyD/EyW 0.56 in male, 2.30 in female; PWA/ PWB 1.24–1.28; female antennae (Fig. 26) as long as male (Fig. 25); whole elytra yellowish brown, in female pointed at apex.
Etymology. The species name is dedicated to Mr. Wen -Chuan Liao, the collector of the holotype; noun in genitive case standing in apposition.
Distribution (Fig. 126). Taiwan.
