Cladophorus kailakiensis sp. nov.

(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.
