( Figs. 17, 29 , 46 , 71–72 ) Type material. Holotype . Male , Indonesia , Papua prov., 3 km N of Bokondini , 03°40´S 138°40´E , 1750–1900 m (JB0121, LMBC ) ; Paratype , male, same locality data (JB0103, LMBC ) . Diagnosis. C. pallescens is the only species with black, metallically shining pronotum and yellow elytra except for a humeral patch ( Figs. 29 , 46 ). The yellow form of closely related C. bicolor can be similar in the general appearance, but all available C. bicolor have at least a small apical part of elytra infuscate ( Fig. 33 ). Further, C. pallescens has a robust phallus with the short apex ( Figs. 71–72 ), long antennal lamellae ( Fig. 15 ), and quite large eyes. Description. Male. Body medium-sized, 10.2–10.7 mm long, dark brown to black, pronotum and very narrow humeral margin of elytra dark coloured, rest of elytra light yellow ( Figs. 29 , 46 ). Head small, with quite large hemispherically prominent eyes, frontal interocular distance 1.7 times maximum diameter; antennae flabellate, long, reaching to three quarters of elytral length if inclined, antennomere 3 with lamella 3.0 times longer than stem of antennomere, lamella attached to apex of antennomere ( Fig. 17 ). Pronotum transverse, 1.4 times wider than long at midline, lateral margins slightly elevated, frontal margin moderately projected, frontal angles sharply marked, lateral margins straight, with small bump in posterior third, posterior angles projected, all carinae well-developed ( Fig. 29 ). Elytra flat, parallel-sided, transverse costae well-developed, regular, elytral areoles slightly transverse ( Fig. 45 ). Phallus robust, parallel-sided in apical half, with short slender apical process ( Figs. 71–72 ). Measurements. BL 10.2–10.7 mm , PL 1.30–1.40 mm , PW 1.90–1.95 mm , WH 1.15–1.20 mm , Edist 0.8 mm , Ediam 0.47 mm , LE 8.5–8.9 mm , antennomere 3: stem 0.8 mm , lamella 2.4 mm . Distribution. Central New Guinea , Tolikara regency ( Fig. 3 ) Etymology. The species name refers to the pale coloration of elytra.
