Plateros milenae sp. n.

Type material. Holotype: male, S Sulawesi, 25 km SSE Malino, Gn. Lompobatang, 1800 m, 119.53.31E, 5.17.50S, 26­28 July 1999, Bolm lgt. ( LMBC) ; Paratype: 1 male, 4 females, same locality data ( LMBC) .

Differential diagnosis. Plateros milenae sp. n. is the species with largest male eyes in Sulawesi, only P. kalamensis sp. n. also having eyes diameter larger than interocular distance. The male genitalia enable sure identification ( Figs 5, 6 ). P. milenae sp. n. reminds P. rubromamasensis sp. n. in the shape of the third antennomere ( Figs 24, 26 ), but these species differ in the pronotum colouration.

Description. Body small, slender, parallel­sided, black, only legs brown. Body covered with dense light pubescence, elytral pubescence darker. Head small, eye diameter 1.46 times interocular distance. Antennae moderately robust ( Fig. 24 ), reaching two­fifths of elytral length, antennomeres 3­9 slightly triangular, antennomeres 10­11 parallel­sided. Antennae covered with long erected pubescence. Pronotum 1.5 times width at base than long at midline ( Fig. 16 ). Frontal margin rounded, anterior angles weak, posterior angles acutely projected. Disc shining, with long light pubescence. Elytra parallel­sided, 4.0 times longer than width at humeri. Costae fine, covered with dense black pubescence. Phallus curved apically, internal sac exposed, with sclerotized plate ( Figs 5, 6 ).

Measurements. BL 6.07 mm, WH 1.31 mm PL 0.79 mm, PW 1.17 mm, Ediam 0.42 mm, Edist 0.29 mm.

Distribution. Central Sulawesi Province, Mamasa valley.

Etymology. The specific name " milenae " is a matronym dedicated to Mrs. Milena Tvardikova, the mother of the first author.
