Figs 1 , 15–16.

MATERIAL: Holotype, ♂, Indonesia, S Sulawesi, ca. 10 km NE Bantaeng , 5°26´S 119°55´E, 440 m, 06.I.2020, S. Kazantsev leg. ( ICM).

DESCRIPTION. Male. Testaceous; head, metaventrite and tarsi light brown; antennomeres 3–10 dark brown (antennomere 11 missing in both antennae) ( Fig. 1 ).

Vertex shining, with broad shallow round impression behind antennal prominence. Eyes relatively large, interocular distance ca. 1.4 times shorter than eye diameter. Labrum small, transverse, truncate anteriorly. Palps slender; ultimate palpomeres elongate, widest in the middle, obliquely truncate and flattened at apex. Antennal sockets separated by minute lamina. Antennae attaining to elytral two thirds, from antennomere 3 serrate; antennomere 3 ca. 4.3 times longer than antennomere 2 and 1.2 times shorter than antennomere 4; antennomeres 3–11 with long erect pubescence ( Fig. 1 ).

Pronotum transverse, ca. 1.2 times as wide as long, moderately bisinuate basally and strongly semi-circularly produced anteriorly, with almost parallel, slightly concave sides, conspicuous acute posterior and blunt anterior angles. Scutellum subquadrate, parallel-sided, truncate and medially slightly emarginate at apex ( Fig. 1 ).

Elytra long, ca. 3.6 times longer than wide at humeri, parallel-sided, with four equally developed primary costae; interstices with even rows of small roundish cells; pubescence short and decumbent ( Fig. 1 ).

Legs slender ( Fig. 1 ).

Median lobe of aedeagus relatively short, widened in distal two thirds, with paired toothed blades apically ( Figs 15–16).

Female. Unknown.

Length: 4.9 mm. Width (humerally): 1.1 mm.

ETYMOLOGY. The name of the new species is derived from´Bantaeng´, a locality in South Sulawesi where its type specimen was collected .

DIAGNOSIS. Plateros bantaengensis sp.n., resembling P. lalui Tvardik et Bocák, 2001 in appearance, may be easily separated from all Sulawesi Plateros by the unique structures of the aedeagus ( Figs 15–16).

REMARKS. Antennomere 11 is missing in the left antenna and antennomeres 10–11 are missing in the right antenna of the holotype.
