MATERIAL: Holotype, ♂, Indonesia, N Sulawesi, Bogani Nani Wartabone N.P., 1100 m, 09.VIII.2018, S. Young leg. ( ICM). DESCRIPTION. Male. Dark brown; pronotum, except at disk, elytra and terminal abdominal segments (ventrite 8 and tergites 9–10) testaceous ( Fig. 14 View Figs 10–14 ).

Vertex with conspicuous round impression behind antennal prominence. Eyes moderately large, interocular distance ca. 1.1 times shorter than eye diameter. Labrum small, transverse, truncate anteriorly. Palps slender; ultimate palpomeres narrow, elongate, almost parallel-sided, obliquely truncate and flattened at apex. Antennal sockets separated by minute lamina. Antennae attaining to elytral four fifths, antennomeres 3–10 ramose, rami of antennomeres 3–7 ca. 2 times shorter than stems, rami of antennomeres 8–10 ca. 3.3–5.3 times shorter than stems; antennomere 3 (stem) ca. 3 times longer than antennomere 2 and ca. 1.3 times shorter than antennomere 4; antennomeres 3–11 with very long semi-erect pubescence ( Fig. 14 View Figs 10–14 ).

Pronotum transverse, ca. 1.6 times as wide as long, moderately bisinuate basally and strongly triangularly produced anteriorly, with almost straight sides, short acute posterior and conspicuous blunt anterior angles. Scutellum subquadrate, parallel-sided, slightly emarginate at apex ( Fig. 14 View Figs 10–14 ).

Elytra long, ca. 3.4 times longer than wide at humeri, slightly widening distally, with four equally developed primary costae; interstices with even rows of small subquadrate to elongate sub-rectangular cells; dense pubescence short and decumbent ( Fig. 14 View Figs 10–14 ).

Legs slender ( Fig. 14 View Figs 10–14 ).

Median lobe of aedeagus elongate and narrow, with conspicuously widened and twisted distal third ( Figs 31–32 View Figs 23–32 ).

Female. Unknown.

Length: 5.1 mm. Width (humerally): 1.4 mm.

ETYMOLOGY. The name of the new species is derived from´ Bogani Nani Wartabone´ Park , in North Sulawesi, where its type specimen was collected .

DIAGNOSIS. Plateros wartabonensis sp.n. is easily separable from other Sulawesi Plateros with ramose male antennae by the combination of testaceous upperside and short antennal rami ( Fig. 14 View Figs 10–14 ). It may be distinguished from P. flavidus Kleine, 1933 and P. toliensis Tvardik et Bocák, 2001 , in neither of which males are known, but ramose antennae expected due to their serrate female antennae, by the strongly produced forward anterior pronotal margin. The characteristic male genital structures also distinguish the new species from all Sulawesi congeners ( Figs 31–32 View Figs 23–32 ).
