This species is similar to C . mindanensis Chapin, 1924 from the Philippines , but it is distinguished by the following characters (CORΡORΑΑL +| VΑΝ DΕR WΙΕL 1949): scutellum red; head and pronotum finely and sparsely punctured. Figs 52–58. Metendosternite, terminal parts and genitalia in male of Cladiscus weyersi Kraatz, 1899 . 52 – metendosternite; 53 – pygidium; 54 – ventrite VI; 55 – spicular fork; 56–58 – male genitalia in lateral (56), ventral (57), and dorsal (58) views. Supplementary description. Male ( Fig. 2 ). Head, pronotum, and antennomeres I and II brownish red; antennomeres III to XI, elytra, and legs brownish black. Antennae ( Fig. 16 ) longer than total length of head and pronotum combined; antennomere I swollen and bent; II compact; III to X pectinate, with branches arising at base of antennomeres; XI fusiform. Pronotum smooth at apex; postcoxal projections ( Fig. 35 ) long; prosternal process not extending contact point of postcoxal projections. Elytra with rows of large, deep, asetigerous punctures in basal half; apical margins finely indented. Mesoventrite with sparse setigerous punctures except for central portion. Metaventrite with evenly arranged fine setigerous punctures except for central portion; metaventral anterior process elongate, as wide as mesoventral posterior process. Metendosternite ( Fig. 52 ) without furcal laminae; process extending anteriorly, tapered; furcal arms almost straight, extending anterolaterally. Protibiae ( Fig. 28 ) gently widening from basal 1/3 to apex, weakly curved; meso- and metatibiae almost straight. Tibial spur formula 0–0–0. Apical margin of abdominal ventrite V broadly and weakly emarginate. Apical margin of pygidium ( Fig. 53 ) straight; struts short. Apical margin of ventrite VI ( Fig. 54 ) slightly emarginated. Spicular fork ( Fig. 55 ) with intraspicular plate, which is 1/2 as long as spicular fork. CM ( Figs 56–58 ) covered with large spines and fine spines, 1/4 as long as tegmen. Tegmen shorter than phallus; phallobasic apodeme fused with phallobasic struts. Phallus widest at 1/3, thence tapered apically. Female. Unknown. Measurements and ratios. Male (n Y 2): BL: 8.08–8.82 mm ; PL: 2.08–2.28 mm ; PWA: 1.40 mm ; PWM: 0.73–0.75 mm ; PWB: 0.93–0.98 mm ; EL: 6.00– 6.55 mm ; EW: 1.50–1.63 mm ; EyD: 0.75–0.78 mm ; EyW: 0.38–0.40 mm ; EL/PL: 2.88–2.89; EW/PWA: 1.07–1.16; EW/PWM: 2.07–2.17; EW/PWB: 1.62–1.67; PWA/PWB: 1.44–1.51; PWA/PWM: 1.87–1.93; PWB/PWM: 1.28–1.30; EyD/ EyW: 1.94–2.00.
