( Figs. 11, 25 , 41 , 63–64 ) Type material. Holotype . Male, Papua New Guinea , Pt. Moresby , Kailaki, Berem, 09°26´S 147°33´E , 530–940 m (A00122, LMBC ) ; Paratype , male, Papua New Guinea , Pt. Moresby , Varirata N. P. , 09°26´S 147°22´E , 700–800 m ( A00176 , LMBC ) . Diagnosis. In contrast with distant relationships, C. kailakiensis resembles in the general colour pattern C. manokwarensis ( Figs. 4 , 37–38 ). Both species have brightly yellow coloured pronotum, the extensive black coloured humeral part of elytra and brightly coloured rest of elytra ( Figs. 41–42 ). The molecular phylogeny identified C. mindikensis as a sister species ( Fig. 4 ) and these species differ in the elytral and pronotal coloration ( Figs. 25, 27 , 41, 43 ) and the length of antennal lamellae ( Figs. 11, 13 ). Description. Male. Body medium-sized, 10.5–12.9 mm long, body dark brown to black, pronotum and substantial part of elytra brightly yellow ( Fig. 41 ), humeral tenth of elytra black, other parts of elytra brightly yellow ( Fig. 41 ). Head small, with small, hemispherically prominent eyes, frontal interocular distance 1.87 times maximum eye diameter; antennae long, reaching beyond two thirds of elytral length, flabellate, antennomere 3 with lamella 2.56 times longer than stem of antennomere, lamella attached close to middle part of antennomere ( Fig. 11 ). Pronotum transverse, 1.3 times wider than long at midline, lateral margins elevated, frontal margin widely rounded, frontal angles inconspicuous, rounded, lateral margins slightly convex, posterior angles moderately prominent, postero-lateral carinae weak ( Fig. 25 ). Elytra flat, slightly widened posteriorly, transverse costae weak, regular, elytral areoles slightly transverse ( Fig. 41 ). Phallus robust, parallel-sided in middle part, apparently constricted basally, with gradually acuminate apex ( Figs. 63–64 ). Measurements. BL 10.5–12.9 mm , PL 1.5–1.8 mm , PW 2.20–2.65 mm , WH 1.30–1.54 mm , Edist 0.99 mm , Ediam 0.53 mm , LE 10.6 mm , antennomere 3: stem 0.9 mm , lamella 2.3 mm . Distribution. Eastern New Guinea , the southern slope of the Owen Stanley Range ( Fig. 3 ). Etymology. The epithet refers to the local name ‘Kailaki’, the type locality of the species.
