Plateros tanatorajensis 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, 1 female, same locality data ( LMBC) .

Differential diagnosis. Plateros tanatorajensis sp. n. and P. rubromamasensis sp. n. are two species with light coloured elytral margins, but margins of P. tanatorajensis sp. n. are yellowish, narrower and less apparent. These species differ substantially in the shape of antennae ( P. tanatorajensis sp. n. having antennae acutely serrate; Figs 26, 27 ), in light pronotal margins of P. tanatorajensis sp. n., and in the shape of male genitalia ( Figs 9 , 11 ).

Description. Body small, slender, parallel­sided, black, only legs and margins of pronotum brown, lateral margins of elytra yellow. Head small, hemispherically prominent, interocular distance 1.09 times eye diameter. Antennae reaching slightly over two­thirds of elytral length. Antennomeres 3­10 acutely serrate, flattened, antennomere 5 with apical process as long as width of trunk of antennomere. Antennomeres bearing long erected pubescence ( Fig. 27 ). Pronotum 1.65 times wider at base than long at midline. Frontal margin apparently projected forwards, anterior angles obtuse, apparent, posterior angles acutely projected ( Fig. 19 ). Disc with deep depression at anterior angles, covered with dense pubescence. Elytra parallel­sided, longitudinal costae fine, covered with very dense pubescence. Male genitalia very slender, curved in middle part, widened apically, internal sac membranous ( Figs 9, 10 ).

Measurements. BL 6.33 mm, WH 1.57 mm PL 0.83 mm, PW 1.37 mm, Ediam 0.39 mm, Edist 0.42 mm.

Distribution. Central Sulawesi Province, Mamasa valley.

Etymology. The specific name " tanatorajensis " is derived from the name Tana Toraja, the highland region in the central part of Sulawesi.
