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). Paratypes. Male, ditto; 2 males, W. Sulawesi, 25 km E Mamasa (Kalama), 1100 m, 119.28.39E 3.02.10S, 1.–3. July 2001, Bolm lgt. (LMBC).
Differential diagnosis. W. hanae sp. nov. is the only species of Wakarumbia with two separate simple spines in the internal sac (Figs 5–6). It belongs to a group of dark colored species with considerably rotated apical half of the phallus (W. hanae, W. petri Bocak, 2001, W. celebensis Bocak, 2000 and W. flavohumeralis Bocak, 2000. Only W. petri resembles W. hanae in the uniformly black coloration, but these species differ in the shape of the phallus (Figs 5–6).
Description. Body medium-sized, uniformly dark brown to black, covered with dense grayish pubescence. Head small, partly hidden by pronotum, eyes small, hemispherically prominent, frontal distance between eyes 1.26 times eye diameter. Antennae compressed, antennomeres 3–11 quite slender, parallelsided, antennomere 3 2.75 times longer than maximum width. Pronotum flat, 1.33 times wider than long, with well developed carinae, disc densely pubescent. Elytra parallel-sided, 3.70 times longer than width at humeri, reticulate cells regular, mostly transverse. Phallus slender in middle part, apical half strongly rotated, with two separate sclerotized spines in middle and basal part (Figs 5–6).
