Figs 4 , 21–22.

MATERIAL: Holotype, ♂, Indonesia, S Sulawesi, Latimojong Mts,N slopes [of] Sinaji Mt., env. Uluway , 3°18´36´´S 120°01´40´´E, 2000 m, 19– 20.01.2020, S. Kazantsev leg. ( ICM).

DESCRIPTION. Male. Uniformly black ( Fig. 4 ).

Vertex with small inconspicuous round impression behind antennal prominence. Eyes relatively small, interocular distance ca. 1.2 times greater than eye diameter. Labrum small, transverse, truncate anteriorly. Palps slender; ultimate palpomeres small, elongate, slightly widened distally, obliquely truncate and flattened at apex. Antennal sockets separated by minute lamina. Antennae attaining to elytral two thirds, filiform; antennomere 3 ca. 2.3 times longer than antennomere 2 and ca. 1.2 times shorter than antennomere 4; antennomeres 3–11 with scarce erect pubescence ( Fig. 4 ).

Pronotum transverse, ca. 1.1 times as wide as long, moderately bisinuate basally and strongly produced forward anteriorly, with straight, parallel-sided lateral margins, straight posterior and conspicuous blunt anterior angles. Scutellum transverse, slightly narrowing distally, truncate at apex ( Fig. 4 ).

Elytra long, ca. 4 times longer than wide at humeri, parallel-sided, with four primary costae, costae 2 and 4 noticeably more raised than costae 1 and 3; interstices with uneven rows of small roundish cells; dense pubescence short and semi-erect ( Fig. 4 ).

Legs slender (Fig.).

Median lobe of aedeagus more or less straight, its basal half with distinct constriction, distal half bearing dorsal paired hooked blades and ventral triangular projection ( Figs 21–22).

Female. Unknown.

Length: 4.8 mm. Width (humerally): 0.9 mm.

ETYMOLOGY. The name of the new species is derived from the ‘ Latimojong Mountains’ , a locality in South Sulawesi where its type specimen was collected .

DIAGNOSIS. Plateros latimojongensis sp.n., being similar in coloration and general appearance to P. orobuensis Tvardik et Bocák, 2001 , is easily separable by the shape of the median lobe of the aedeagus with paired hooked blades ( Figs 21–22).
