Holotype (male): Indonesia, Papua: Dorei Hum [? 0° 54' S, 134° 3' E], II.1875, Beccari, labelled " Pseudonicsara hura ", depository: Museo Civico di Storia Naturale "Giacomo Doria", Genova , Italy ( MCSN).

Diagnosis. P. hum comes close to P. nana and P. spinibranchis in that the male tenth abdominal tergite is slightly globular with the apex deeply excised in middle. It differs by the apical lobes of the tenth abdominal tergite being depressed ( Fig. 123), the cercus has both apico-internal processes spinose ( Fig. 165), the basointernal processes inserted upon each other ( Figs. 257–258), and the apical parts of the are titillators narrow with the apex rounded ( Figs. 428–429). Differences to other species are outlined in the key.

Description. Fastigium verticis in front of eyes 0,9 mm, from base 1,4 mm; dorsal eye length 1,7 mm; index fastigium verticis from base: eye length 0.8–0.9. Face rugose. Tegmen little surpassing hind knees; rather narrow; basal two thirds with pre-subcostal area widened, apical third narrow. Prosternal spine short; mesosternal lobes rounded. Femora with the following number of spines on ventral margins: fore femur 6 external, 6 internal; mid femur 6–7 external, 2 internal near base; hind femur 10–14 external, 3–6 minute internal in basal area.

Male. Stridulatory file with about 110 teeth ( Fig. 90). Tenth abdominal tergite globular, apex roundly excised in middle and with long obtuse projecting lobes on both sides of excision ( Figs. 123, 165). Cerci short, stout, with external surface convex, internal surface concave, shining and with a low dorsal and a high ventral carina, both carinae with a long projection at base and a short projection at apex; basal projections compressed, apex hook-shaped; apical projections conical, apex acute ( Figs. 165, 227, 257–258). Styli very long and thin, longer than half the length of subgenital plate ( Fig. 295).

Titillators with apical part ovoid, ventro-apical surface dark, with clinging hairs and a fleck of little longer hairs surpassing apex of titillator; margin granular; apico-lateral sclerite band-shaped, curved [broken in preparation] ( Figs. 323, 371, 428–429).

Female unknown.

Coloration. Uniformly medium brown (discoloured due to former conservation in alcohol). Face concolorous, dorsal area of clypeus dark brown, mandibles blackish brown. Hind knees darkened.

Measurements of male: body 25, pronotum 7.8, tegmen 24, hind femur 17 mm.

Etymology. Named after the type locality; noun in apposition.
