Fig. 6 .

MATERIAL: Holotype, ♀, Indonesia, S Sulawesi, N slopes [of] Mt. Pangopango , 3°09´46´´S 119°49´45´´E, 1740–1780 m, 9– 11.I.2020, S. Kazantsev leg. ( ICM).

DESCRIPTION. Female. Dark brown to black; pronotal margins light brown; elytra, except relatively broad sutural stripe, testaceous ( Fig. 6 ).

Vertex with prominent transverse impression behind antennal prominence. Eyes relatively small, interocular distance ca. 1.2 times greater than eye diameter. Labrum transverse, anteriorly slightly emarginate. Palps slender; ultimate palpomeres considerably longer than wide, almost parallel-sided, obliquely truncate and flattened at apex. Antennal sockets separated by relatively broad lamina. Antennae attaining to elytral middle, antennomeres 4–10 strongly serrate; antennomere 3 ca. 3.4 times longer than antennomere 2 and 1.2 times longer than antennomere 4; antennomeres 3–11 with relatively long decumbent pubescence and separate longer erect apical bristles ( Fig. 6 ).

Pronotum transverse, ca. 1.3 times as wide as long, trapezoidal, slightly bisinuate posteriorly and strongly semi-circularly produced anteriorly, with long sharp posterior and obsolete anterior angles. Scutellum subquadrate, slightly widening distally, medially minutely emarginate at apex ( Fig. 6 ).

Elytra long, ca. 3.3 times longer than wide at humeri, parallel-sided, with four almost equally developed primary costae; interstices with even rows of small roundish cells; pubescence short and decumbent ( Fig. 6 ).

Male. Unknown.

Length: 8.5 mm. Width (humerally): 2.0 mm.

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

DIAGNOSIS. Plateros pangoensis sp.n. can be easily separated from all other Sulawesi Plateros by the coloration ( Fig. 6 ).

REMARKS. Plateros pangoensis sp.n. is being described after a female due to its peculiar coloration pattern, very different from all other Sulawesi Plateros . As the serrate female antennae are usually characteristic of species with ramose male antennae, it seems reasonable to expect the same antennal structure in P. pangoensis sp.n. males.
