Figs 3 View Figs 1–3 , 19–20.

MATERIAL: Holotype, ♂, Indonesia, N Sulawesi, Bogani Nani Wartabone N.P., 17–25.I.2011, A. Gorochov leg. ( ZIN).

DESCRIPTION. Male. Dark brown; narrow elytral margins, trochanters and bases of femora light brown ( Fig. 3 View Figs 1–3 ).

Vertex with transverse impression behind antennal prominence. Eyes relatively small, interocular distance ca. 1.2 times greater than eye diameter. Labrum small, transverse, almost truncate anteriorly. Palps slender; ultimate palpomeres small, elongate, widest in the middle, obliquely truncate and flattened at apex. Antennal sockets separated by minute lamina. Antennae attaining to elytral two thirds, narrow, antennomeres 5–7 feebly serrate; antennomere 3 ca. 2.8 times longer than antennomere 2 and 1.4 times shorter than antennomere 4; antennomeres 3–11 with relatively long scarce erect pubescence ( Fig. 3 View Figs 1–3 ).

Pronotum transverse, ca. 1.8 times as wide as long, trapezoidal, slightly bisinuate basally and semi-circularly produced anteriorly, with long narrow acute posterior and blunt rounded anterior angles. Scutellum subquadrate, parallel-sided, truncate at apex ( Fig. 3 View Figs 1–3 ).

Elytra long, ca. 3.9 times longer than wide at humeri, parallel-sided, slightly concave at lateral margins, with four equally developed primary costae; interstices with even rows of small subquadrate cells; pubescence short and decumbent ( Fig. 3 View Figs 1–3 ).

Median lobe of aedeagus relatively straight, narrow and conspicuously widened distally, provided with long and broad bidental blade ( Figs 19–20).

Female. Unknown.

Length: 7.0 mm. Width (humerally): 1.6 mm.

ETYMOLOGY. The new species is named after Dr. A.V. Gorochov ( ZIN) who collected the unique type specimen .

DIAGNOSIS. Plateros gorochovi sp.n. can be readily distinguished from all Sulawesi Plateros by the long narrow posterior pronotal angles and the peculiar aedeagal structures ( Figs 3 View Figs 1–3 , 19–20).
