Cladophorus craterensis sp. nov.

(Figs. 8, 22, 38, 57–58)

Type material. Holotype. Male. Papua New Guinea, Crater Mt., Haia, 06°42´S 145°00´E, 780 m (A00171, LMBC).

Diagnosis. Cladophorus craterensis belongs to the group of mostly light-yellow coloured species such as C. praecipuus, C. riedeli, and C. motykai . The phylogenetic analysis showed that these species are not closely related (Fig. 4) despite the quite similar shape of their male genitalia (Fig. 57–58, 69–70, 73–76). The closest relative of C. craterensis is C. motykai and these two species differ in short lamellae of C. craterensis and the long lamellae of C. motykai (Figs. 8, 14).

Description. Male. Body medium-sized, 13.3 mm long, dark brown to black, pronotum and elytra almost completely uniformly yellow, only very narrow part of humeral margin and the apex slightly darkened (Fig. 38), scutellum black. Head small, with small hemispherically prominent eyes, frontal interocular distance 1.78 times maximum eye diameter; antennae long, reaching two thirds of elytral length, flabellate, antennomere 3 with lamella 1.4 times longer than stem of antennomere, lamella attached to apical part of antennomere (Fig. 8). Pronotum transverse, 1.5 times wider than long at midline, lateral margins conspicuously elevated, frontal margin slightly rounded, frontal angles obtuse, inconspicuous, lateral margins straight, posterior angles prominent, postero-lateral carinae weak in middle of pronotal disc, median anterior carina weak (Fig. 22). Elytra flat, very slightly widened posteriorly, transverse costae weak, partly covered by pubescence, elytral areoles slightly transverse (Fig. 38). Phallus moderately slender, parallel-sided, gradually acuminate apically (Figs. 57–58).

Measurements. BL 13.3 mm, PL 1.74 mm, PW 2.58 mm, WH 1.56 mm, Edist 0.96 mm, Ediam 0.54 mm, LE 11.1 mm, antennomere 3: stem 1.2 mm, lamella 1.6 mm.

Distribution. Eastern New Guinea, Chimbu province (Fig. 3).

Etymology. The epithet refers to the Crater Mts., the type locality of the species.
