( Figs. 7, 21 , 37 , 55–56 ) Type material. Holotype , male. Indonesia , Papua Prov., Yapen Island , Road Konti Unai –Ambaid, 136°19´E 1°45´S , 600–700 m ( A00407 , LMBC ) ; Paratypes , 2 males , same locality data (A00406, 408, LMBC ) . Diagnosis. Cladophorus boceki is closely related to C. praecipuus ( Fig. 4 ) and both species are similar in the general appearance ( Figs. 21, 30 , 37, 47 ). Despite their very low genetic divergence, these species are clearly defined by the length of antennal lamella 3 ( Figs. 7, 14 ), the relative size of male eyes (ratio 1.55 and 2.02 in C. boceki and C. praecipuus , respectively) and C. boceki has a robust phallus with the gradually pointed apical part unlike C. praecipuus , which has the slender phallus, parallel-sided in four-fifths of its length ( Figs. 55–56, 73–74 ). Description. Male. Body large, 13.6–14.1 mm long, dark brown to black, elytra yellow, only apical 1/12 black ( Fig. 37 ), transition between dark and light coloured parts of elytra abrupt, only elytral costae with slightly larger dark part ( Fig. 37 ). Head small, with hemispherically prominent eyes, frontal interocular distance 1.52 times maximum diameter; antennae long, reaching two thirds of elytral length, flabellate, antennomere 3 with lamella 2.4 times longer than stem of antennomere, lamella attached to apical part of antennomere ( Fig. 7 ). Pronotum transverse, 1.5 times wider than long at midline, lateral margins slightly elevated, frontal margin rounded, lateral margins bi-sinuate, frontal angles well marked, posterior angles sharply prominent, postero-lateral carinae weak ( Fig. 21 ). Elytra flat, slightly widened posteriorly, transverse costae weak, partly covered by pubescence, elytral areoles slightly transverse ( Fig. 37 ). Phallus robust, widest in apical third, gradually acuminate apically, with robust apical process ( Figs. 55–56 ). Measurements. BL 13.6–14.1 mm , PL 1.95–2.0 mm, PW 2.85–2.95 mm , WH 1.60–1.65 mm , Edist 1.02 mm , Ediam 0.66 mm , LE 11.6 mm , antennomere 3: stem 1.1 mm , lamella 2.6 mm . Distribution. Yapen Island ( Fig. 3 ). Etymology. The species name is a patronym in honor of Matej Bocek (Olomouc).
