Differential diagnosis.
O. xunyanbaensis
resembles
O. hainanensis
. These species differ mainly in elytral coloration, when
O. xunyanbaensis
has entire elytra brown while primary elytral costae of
O. hainanensis
are yellow to brown and secondary and transverse costae are dark brown.
O. xunyanbaensis
has well visible pronotal fronto-lateral carinae while in
O. hainanensis
the carinae are very weak. The phallus of
O. xunyanbaensis
is robust, almost parallel-sided, slender apically, those of
O. hainanensis
has widely rounded apical part (
Figs. 29–32
).
Description.
Male. Body ~
9 mm
long, elongate, 4.4–4.8 times longer than width at humeri; entire body dark brown, only elytra lighter brown; whole body covered with short, dense pubescence. Head with hemispherically prominent eyes, interocular distance 1.00–1.08 times larger than maximum eye diameter. Antennomeres 3-10 flabellate (
Fig. 14
), apical antennomere slender, parallel-sided. Pronotum flat, trapezoidal, 1.3–1.5 times wider at base than long at midline, with strong middle and frontal carinae, postero-lateral carinae weaker (
Fig. 6
). Elytra slender, widened backward, 3.8–4.0 times longer than their combined width at humeri, with four strong primary costae and five irregularly developed secondary costae (
Fig. 20
). Phallus only slightly widened apically, almost parallel-sided, with gradually slenderer apical part; internal sac with inconspicuous sclerotized and pigmented structures (
Figs. 29–30
).
