Material examined. 10 males Indonesia , Papua prov., Elelim , km 5 on the Apalapsili road, S03°49´ E139°22´ , 580 m (JB0562–66) ; Indonesia , Papua , Dombomi , Lower Pass Valley , 1150 m , S03°50´ E 139°10´ (JB0514–15, 18, 20) ; Indonesia , Papua prov., E slope of the Cyclops Mts. , 450 m , S02°31´ E140°42´ (JB0715, all LMBC ) . Diagnosis. Cladophorus praecipuus and C. boceki are closely related species ( Fig. 4 ) and they are very similar in the general appearance and coloration ( Figs. 21, 30 , 37, 47 ). These species differ in the length of antennal lamellae and the size of eyes. C. praecipuus has the apparently shorter lamella of the antennomere 3 ( Fig. 16 ) and a slender phallus ( Figs. 73–74 ). Redescription. Male. Body medium-sized, 11.0– 12.1 mm long, dark brown to black, thorax and abdomen with apparent blue metallic shine, pronotum and elytra except apical part brightly yellow, apical part of elytra slightly infuscate, seldom light coloured, transition between light and dark coloured part of elytra abrupt ( Figs. 30 , 47 ). Head small, with small, hemispherically prominent eyes, frontal interocular distance 2.0 times maximum diameter; antennae flabellate, long, reaching to three quarters of elytral length if inclined, antennomere 3 with lamella 1.3 times longer than stem, lamella attached to apical part of antennomere ( Fig. 14 ). Pronotum transverse, 1.5 times wider than long at midline, lateral margins elevated, frontal margin almost straight, frontal angles clearly marked, lateral margins straight to convex, posterior angles projected, all carinae well-developed ( Fig. 30 ). Elytra flat, subparallel-sided, transverse costae well-developed, regular, elytral areoles slightly transverse ( Fig. 47 ). Phallus slender, subparallel-sided in apical half, with gradually acuminate apical process ( Figs. 73–74 ). Color polymorphism. The extent of the black coloured part of elytra is variable, but never more than one ninth of elytral length was dark colored. We found only a single specimen with uniformly yellow colored elytra. Measurements. BL 11.0– 12.1 mm , PL 1.40–1.60 mm , PW 2.25–2.40 mm , WH 1.65–1.75 mm , Edist 0.99 mm , Ediam 0.49 mm , LE 9.2–9.9 mm , antennomere 3: stem 1.0 mm, lamella 1.3 mm . Distribution. Central New Guinea , Yalimo and Jayapura regencies ( Fig. 3 ).
