Cladiscus terminalis Schenkling, 1912: 322 [original description]. CORΡORΑΑL +| VΑΝ DΕR WΙΕL (1949): 195 [key to species]; CORΡORΑΑL (1950): 23 [listed].
Type locality. Taiwan, Taihorinsho (Y Talin, Chiayi County).
Type material. HOLOΤYΡΕ: 1 ♁, ‘Taihorinsho | Formosa | H Sauter’, ‘7. X’, ‘Holotypus’, ‘♂’, ‘DEI Coleoptera | L 200094’ (SDEI). I examined the holotype based on the photos available in Integrated Insect Types Database of Taiwanese species at http://twinsecttype.nmns.edu.tw/species/ orig/?id Y 9CE4F73E4A51DA32414C50E82EFFDFAF
Additional specimens examined. TAIWAN: TΑIΡEI COUΝτ Y: Mt. Sangmingshan, 24.viii.1966, 1 ♁, H. Kamiya leg. (EUMJ). PIΝGτUΝG COUΝτ Y: Chiupeng, Manchou Township, 16.x.2016, 1 ♁, K. Takahashi leg. (KSCJ); Mt. Dahanshan, Chunri Township, 13.vi.2015, 1 ♁, Sinyan Shih leg. (SSCT). NΑΝτOU COUΝτ Y: Musha, Renai Township, alt. 1,700 m, 24–28.viii.2016, 1 ♀, M. Tanaka leg. (MTCJ).
Differential diagnosis. This species is similar to C. liaoi sp. nov., but distinguished by the following characters: EyD/ EyW 0.68 in male, 1.53 in female; PWA/PWB 1.12–1.24; female antennae (Fig. 20) relatively shorter than male (Fig. 19); apex of elytra round, partly black.
Supplementary description. Male (Fig. 4). Head, pronotum, elytra except for apex yellowish brown; antennae, elytra at apex., and legs brownish black.
Antennae (Fig. 19) 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; tubercles developed in middle; postcoxal projections (Fig. 37) short; prosternal process not extending contact point of postcoxal projections. Elytra with rows of deep, large, asetigerous punctures before apex; apical margins not indented. Mesoventrite evenly covered with setigerous punctures. Metaventral anterior process shorter and wider than mesoventral posterior process. Metendosternite (Fig. 71) without furcal laminae; process extending slightly anteriorly; furcal arms almost straight, extending anterolaterally.
Protibiae (Fig. 30) gently widening to apex., weakly curved. Tibial spur formula 0–0–0.
Apical margin of abdominal ventrite V broadly and slightly emarginated. Apical margin of pygidium (Fig. 72) almost straight; struts short. Apical margin of ventrite VI (Fig. 73) almost straight. Spicular fork (Fig. 74) with short intraspicular plate, which is 1/4 of spicular fork.
CM (Figs 77–79) with fine spines, about 1/2 as long as tegmen. 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, but EyD/EyW 1.53; antennae (Fig. 20) weakly serrate; central portion of metaventrite with pair of bundles of elongate setae-like trichobothria; apical margin of ventrite V truncated broadly and deeply in middle.
Apical margin of pygidium (Fig. 75) almost straight; struts short. Apical margin of ventrite VI (Fig. 76) incised in middle; apodeme 2/3 as long as total length.
Spermatheca weakly sclerotized; Sc lacking. CPr (Figs 80–82) distally trifurcate; central process large; dorsolateral and ventrolateral processes relatively short.
