Diagnosis.
C. humeralis
has a unique elytral colour pattern with brown humeri and a longitudinal patch in the posterior part of each elytron (
Fig. 40
). Further, the phallus of this species is robust and gradually acuminate apically (
Figs. 61–62
).
C. manokwarensis
was identified as a sister species of
C. humeralis
in the molecular phylogeny (
Fig. 4
). Although these species are very close each to other, they differ besides the colour pattern in the shape of the antennomere 3 and the relative size of eyes. The shape of phallus differs only slightly in this pair of species (
Figs. 61–62, 65–66
)
Redescription.
Male. Body large,
15.5–15.7 mm
long, dark brown to black including pronotum and substantial part of elytra (
Fig. 40
), humeri light brown, bright humeral patches separated by dark coloured area along inner margin of elytra; additionally long, light patch in posterior part of each elytron, posterior patch with gradual transition between dark and light coloured areas of elytron (
Fig. 40
). Head small, with hemispherically prominent eyes, frontal interocular distance 1.92 times maximum diameter; antennae long, reaching beyond two thirds of elytral length, flabellate, antennomere 3 with lamella 2.55 times longer than stem, lamella attached to apical part of antennomere (
Fig. 10
). Pronotum transverse, 1.43 times wider than long at midline, lateral margins apparently elevated, frontal margin widely rounded, frontal angles inconspicuous, rounded, lateral margins slightly convex, posterior angles prominent, all carinae well-developed (
Fig. 24
). Elytra flat, slender, subparallel-sided, transverse costae well-developed, regular, elytral areoles slightly transverse (
Fig. 40
). Phallus robust, parallel-sided in middle, with gradually acuminate apex (
Figs. 61–62
).
