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.I.2020, S. Kazantsev leg. ( ICM).

DESCRIPTION. Female. Dark brown to black; elytral apices, with lateral streak extending to proximal third, testaceous ( Fig. 10 ).

Vertex with inconspicuous transverse impression and two small roundish pits behind antennal prominence. Eyes relatively small, interocular distance ca. 1.4 times greater than eye diameter. Labrum small, transverse, almost 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. 2.2 times longer than antennomere 2 and ca. 1.3 times shorter than antennomere 4; antennomeres 3–11 with short decumbent pubescence and separate longer erect bristles ( Figs 10–11 ).

Pronotum transverse, ca. 1.4 times as wide as long, semitrapezoidal, moderately bisinuate posteriorly and semi-circularly produced anteriorly, densely pubescent, with long sharp posterior and blunt rounded anterior angles. Scutellum transverse, almost parallel-sided, medially emarginate at apex ( Figs 10–11 ).

Elytra long, ca. 3.6 times longer than wide at humeri, parallel-sided, densely pubescent, with four almost equally developed primary costae, only costa 3 noticeably weaker in distal fourth; interstices with even proximally to uneven distally rows of small roundish cells; pubescence dense, short and decumbent ( Fig. 10 ).

Male. Unknown.

Length: 6.1 mm. Width (humerally): 1.5 mm.

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

DIAGNOSIS. Plateros uluwayensis sp.n. can be easily separated from all other Sulawesi Plateros by the coloration ( Fig. 10 ).

REMARKS. Plateros uluwayensis sp.n. is being described after a female due to its peculiar coloration pattern, very different from all other Sulawesi Plateros .
