Sulabanus brunneus sp. nov.

(Figs. 33–34)

Type material. Holotype. Male. C. Sulawesi, 38 km SE, Pendolo vill., 120.46.55E, 2.14.03 S, 17 July 1999, 1200 m, Bolm lgt. 3 paratypes. 2 males, locality data as the holotype; 1 male, S. Sulawesi, 8 km W Mamasa, 119.20.32E, 2.56.13S, 18-21 July 1999. Bolm lgt. ( LMBC).

Differential diagnosis. Sulabanus brunneus resembles S. dumongabonensis and S. rufomarginatus in the coloration of the elytra, but these species differ in the shape of male genitalia (Figs. 31–36). The phallus of S. brunneus is constricted in the apical part and does not have any erect setae in the middle part of the phallus.

Description. Body dark brown to black, margins of pronotum, trochanters, and bases of femora light brown; elytra slightly lighter in humeral third. Head partly hidden by pronotum. Frontal interocular distance 1.42 times eye diameter. Pronotum flat, 1.02 times wider that long. Elytra parallel–sided, 3.2 times longer than width at humeri. Phallus widest at apical part, slightly constricted at middle, internal sac straight (Figs. 33– 34).

Measurements. BL 6.45 mm, HW 1.65 mm, PL 0.96 mm, PW 1.06 mm, Ediam 0.34 mm, Edist 0.50 mm, EL 5.25 mm.

Distribution. Sulawesi, known from the central part of Sulawesi from western Tana Toraja to the Poso Lake.

Etymology. The specific epithet is derived from the colouration of the pronotal margins.

Remark. The specimen from the Mamasa valley has a distinctly lighter humeral area of the elytra but male genitalia are very similar to the other specimens and we regard both populations as S. brunneus . Va r ia - tion of the color pattern in various populations of mimetic lycids has been observed also in other genera of Metriorrhynchini (Bocak, personal observation).
