Calcaeron sundaicus sp. nov.

(Figs. 48–52)

Description

Male. Dark brown. Elytral costae and suture basally and trochanter­femoral joints testaceous.

Head feebly grooved behind antennal prominence. Eyes relatively large (interocular distance about twice as long as the radius). Ultimate joint of maxillary palpi about 3 times longer than palpomere 3. Antennae slightly reaching over elytral middle, with antennomere 3 and following antennomeres subequal in length to scape.

Pronotum elongate, 1.2 times longer than wide, anterior half roughly punctured, with conspicuous median carina; lateral margins parallel­sided, with hind angles acute and moderately produced latero­posteriorly. Scutellum square, parallel­sided, rounded and finely emarginate at apex.

Elytra long, 3.5 times longer than wide humerally, almost parallel­sided, interstices with 2 to 3 rows of irregular punctures. Dense pubescence short and decumbent.

Metatrochanters with blunt posterior angles.

Aedeagus with straight median lobe and relatively short narrow inner sac (Figs. 51– 52).

Length: 4.8–5.1 mm. Width (humerally): 1.1–1.2 mm.

Female. Unknown.

FIGURES 48–54. Details of Calcaeron gen. nov. 48 — C. sundaicus sp. nov., male, protibia; 49 — same, protarsal claw; 50 — same, ultimate sternite; 51 — same, aedeagus, dorsally; 52 — same, laterally; 53 — C. baluensis sp. nov., male, aedeagus, dorsally; 54 — same, laterally.

Diagnosis

Calcaeron sundaicus sp. nov. differs from C. baluensis sp. nov., the second known Calcaeron species, by the structures of the inner sac (Fig. 51–52).

Etymology

Named after the Great Sunda region, where the species is distributed.
