MATERIAL: Holotype, ♂, Indonesia, S Sulawesi, W Palopo, trail nr. Puri Rimba Resort , 2°58´00´´S 120°05´13´´E, 720–850 m, 23–27.I.2020, S. Kazantsev leg. ( ICM).

DESCRIPTION. Male. Dark brown to black; pronotum, except anterior median spot,, very bases of elytra, trochanters, proximal half of femora and tibiae basally testaceous ( Fig. 7 ).

Vertex with inconspicuous elongate sub-rectangular impression behind antennal prominence. Eyes moderately large, interocular distance subequal in length to eye diameter. Labrum small, transverse, slightly convex anteriorly. Palps slender; ultimate palpomeres elongate, gradually narrowing distally, glabrous and almost pointed at apex. Antennal sockets separated by narrow lamina. Antennae long, attaining to elytral three fourths, strongly serrate; antennomere 3 ca. 3.3 times longer than antennomere 2 and subequal in length to antennomere 4; antennomeres 3–11 with short erect pubescence ( Fig. 7 ).

Pronotum transverse, ca. 1.4 times as wide as long, bisinuate basally and moderately semi-triangularly produced anteriorly, with almost parallel and straight sides, short acute posterior and noticeable blunt anterior angles. Scutellum subquadrate, parallel-sided, truncate at apex ( Fig. 7 ).

Elytra long, ca. 3.2 times longer than wide at humeri, almost parallel-sided, only slightly concave at sides, with four more or less equally developed primary costae; interstices with even rows of small roundish cells; pubescence short and decumbent ( Fig. 7 ).

Legs slender ( Fig. 7 ).

Median lobe of aedeagus elongate, narrow and straight, abruptly bent distally and retroussé and dentate at apex ( Figs 25–26 ).

Female. Unknown.

Length: 5.2 mm. Width (humerally): 1.2 mm.

ETYMOLOGY. The name of the new species is derived from´ Puri Rimba´, a resort west of Palopo , South Sulawesi, near which its type specimen was collected; also from´rimba´, the Indonesian for´jungle´ .

DIAGNOSIS. Plateros rimbaensis sp.n. can be placed near P. celebensis Pic, 1921 of a similar coloration pattern, separable by the anterior dark pronotal spot ( Fig. 7 ); it also differs from all known Sulawesi Plateros in the elongate, narrow and straight medial lobe of the aedeagus, abruptly bent distally and retroussé and dentate at apex ( Figs 25–26 ).
