DESCRIPTION. Male. Dark brown to black; pronotum, scutellum and elytra testaceous ( Fig. 32 View Figs 29–40 ).

Vertex with two distinct elongate narrow impressions behind antennal prominence. Eyes large, interocular distance ca. 1.2 times shorter than eye diameter. Labrum small, transverse, truncate anteriorly. Palps slender; ultimate palpomeres considerably longer than wide, narrow, almost parallel-sided in proximal two thirds, obliquely convex and flattened at apex. Antennal sockets separated by minute lamina. Antennae attaining to elytral middle, antennomeres 3–10 flattened, distinctly pilose; antennomere 3 ca. 5 times longer than antennomere 2 and ca. 1.4 times shorter than antennomere 4; antennomeres 3– 11 with dense short erect pubescence ( Fig. 32 View Figs 29–40 ).

Pronotum transverse, ca. 1.25 times as wide as long, with slightly concave sides, moderately bisinuate basally and semi-circularly produced anteriorly; with short acute, only slightly protruding laterally posterior and rounded anterior angles. Scutellum transverse, narrowing distally, minutely emarginate at apex ( Fig. 32 View Figs 29–40 ).

Elytra long, ca. 3.6 times longer than wide at humeri, slightly widening from humeri; with four almost equally developed primary costae, not significantly different from secondary ones; interstices with even rows of small subquadrate cells; pubescence dense, short and decumbent, obscuring reticulation ( Fig. 32 View Figs 29–40 ).

Legs slender; femoris and tibiae narrow, subequal in length ( Fig. 32 View Figs 29–40 ).

Aedeagus asymmetrical, with narrow phallobase and approximate, but not contiguous phallobasal lateral plates; median lobe straight and narrow, narrowed before proximal nodosity, with dentate distal lobes and only slightly curved apical portion ( Figs 139–140 View Figs 129–144 ).

Female. Unknown.

Length: 7.8–7.9 mm. Width (humerally): 1.8–1.9 mm.

ETYMOLOGY. The name of the new species is derived from the species name ‘ planatus ’ and the Latin for ‘mime’, alluding to the similarity of these two taxa.

DIAGNOSIS. Plateros planatomimus sp.n. may be distinguished from the similar-looking P. planatus Waterhouse, 1879 by the distinctly more pilose antennae and more elongate and rounded anteriorly pronotum ( Fig. 32 View Figs 29–40 ), as well as by the more elongate aedeagus, narrowed before proximal nodosity, with dentate distal lobes and less curved apical portion ( Figs 139–140 View Figs 129–144 ).

DISTRIBUTION. Vietnam, Thailand, Laos.
