Propyropterus (s. str.) plateroides sp. n. ( Figs. 54–55 )

Description

Male. Black. Pronotum, scutellum and elytra bright red.

Head flat, with longitudinal depression behind antennal prominence. Eyes small (interocular distance about 4 times as long as the radius). Maxillary palps slender, with ultimate palpomere elongate, widened and flattened apically, about two thirds of length of palpomeres 2 and 3 combined. Ultimate labial palpomere widened apically and considerably larger than palpomeres 2 and 3. Antennae filiform, antennomeres 4–11 slightly compressed, extending to approximately three fourths the length of elytra; antennomere 3 only slightly longer and wider than antennomere 2 and both combined about 1.6 times shorter than antennomere 4; antennomeres 4–11 gradually increasing in length; antennomeres 1–3 with decumbent pubescence, antennomeres 4–11 with short erect pubescence.

Pronotum transverse, 1.1 times wider than long, trapezoidal, with pronounced, blunt anterior angles and conspicuous acute posterior angles. Median areola well­developed, rhomboidal, connected with side margins by prominent, curved carinae. Scutellum elongate, parallel­sided and deeply incised at apex.

Elytra relatively long, about 3 times longer than wide at humeri, noticeably widening posteriorly, with 4 equally developed primary costae; interstices with double rows of weak, irregular cells, with secondary costae more or less prominent and straight in basal fourth. Minute decumbent pubescence distributed along costae.

Legs slender and narrow; metatrochanters short, with rounded posterior angles; tarsomere 1 with plantar pad occupying about half of the tarsomere.

Median lobe of aedeagus narrow, slightly curved in lateral view, with a pair of minute teeth in preapical portion ( Figs. 54–55 ).

Length: 12.9 mm. Width (humerally): 3.7 mm.

Female. Unknown.

Diagnosis

P. plateroides sp. n. differs from P. kanoi Nakane and P. pygidialis Nakane by its uniformly black underside and in the details of the structure of aedeagus ( Figs. 54–55 ).

Etymology

The name is derived from the genus Plateros Bourgeois due to the similarity of the aedeagus of the new species to that of members the aforementioned genus.
