Wakarumbia decepta sp. nov.

(Figs 3–4)

Type material. Holotype. Male, W. Sulawesi, 8 km W of Mamasa (Nepe), 950 m, 119.20.32E 2.56.13S, 29.– 31. June 2001, Bolm lgt. ( LMBC) . Paratype. Male, W. Sulawesi, 8 km W of Mamasa (Nepe), 950 m, 119.20.32E 2.56.13S, 29.–31. June 2001, Bolm lgt. ( LMBC) .

Differential diagnosis. W. decepta sp. nov. resembles W. kundratai sp. nov. in general appearance, but these species differ in the shape of male genitalia. Those of W. decepta are characteristic in the slenderer basal part of the phallus compared with W. kundratai (Figs 3–4 and 9–10). Additionally, these species can easily be distinguished by the relative size of the eyes.

Description. Body medium-sized, dark brown to black, only pronotal carinae and margins light brown, mouthparts and bases of femora testaceous. Head small, partly hidden by pronotum, eyes small, hemispherically prominent, their frontal distance 1.33 times eye diameter. Antennae compressed, antennomere 3 2.1 times longer than maximum width, antennomeres 3–11 gradually slenderer to apex. Pronotum flat, 1.24 times wider than long, with well developed pronotal carinae, disc shining, covered with sparse long pubescence. Elytra parallel-sided, 2.92 times longer than width at humeri, reticulate cells mostly irregular, transverse to quadrate. Phallus slender, with long tubular part, slightly slenderer in middle of its length, apical part symmetrical (Figs 3–4).

Measurements. BL 5.52 mm, HW 1.54 mm, PL 0.83 mm, PW 1.03 mm, EL 4.50 mm, Ediam 0.33 mm, Edist 0.44 mm.

Distribution. Sulawesi, the Mamasa valley.

Etymology. The specific name, meaning ‘deceiving’, refers to the high similarity with other dark colored species and difficult identification of this species according to the general appearance.
