Plateros kalamensis sp. n.

Type material: Holotype: male, S Sulawesi, 25 km E Mamasa , 1100 m, 119.28.39E, 3.02.10S, 22­24 July 1999, Bolm lgt. ( LMBC) ; Paratype: 1 male, the same data ( LMBC) .

Differential diagnosis. Plateros kalamensis sp. n. is very characteristic by the shape of male genitalia ( Figs 1, 2 ). It shares with P. milenae sp. n. eyes larger than interocular distance and differs from the later in parallel­sided antennomere 3 ( Figs 21, 24 ).

Description. Body small, slender, parallel­sided, black, covered with dense grey pubescence. Head small, eyes hemispherically prominent, eye diameter 1.13 times interocular distance. Antennae slender, reaching two thirds of elytral length, antennomeres almost parallel­sided, with long, erected pubescence ( Fig. 21 ). Apical antennomeres slender, weakly flattened. Pronotum 1.5 times wider at base than long at midline, frontal margin widely rounded, frontal angles very obtuse, inconspicuous ( Fig. 14 ). Posterior angles acutely projected. Pronotal disc mat, with deep depressions at frontal angles, with two short keels at middle of basal margin, covered with long light pubescence. Elytra parallelsided, with fine, inconspicuous costae, covered with dense light pubescence. Male genitalia very slender, widened in apical part, internal sac membranous, exposed ( Figs 1, 2 ).

Measurements. BL 5.50 mm, WH 1.22 mm PL 0.71 mm, PW 1.07 mm, Ediam 0.40 mm, Edist 0.36 mm.

Distribution. Central Sulawesi Province, Mamasa valley.

Etymology. The specific name is derived from the name Kalama, a mountain village in the east of the Mamasa valley.
