Type material. 1 M Holotype, Hyllus barbipalpis   , ZMH, Mus. Godeffroy 8641, Australia: Gayndah [Queensland].

Diagnosis. Male cheliceral retromargins unidentate, both promarginal teeth of similar size, small. Frontal spurs small and cone-like, ventral ones small and lobe-like ( Figs 6 View FIGURE 6 B, E). Fangs with internal outgrowths ( Fig. 6 View FIGURE 6 B). Tegulum elliptic, embolus moderately long, arising at 7 o’clock, spermophore not meandering, palpal tibia elongate. In comparison with similar O. bellus   palpal organ more slender, with tibia relatively longer (its length about 80 % of cymbium length).

Description. Male ( Fig. 6 View FIGURE 6 ) about 7 mm long. Cephalothorax broadest anteriorly (CW = 86 % of CL), with strongly developed cheek swellings, moderately high ( CH = 51 % of CL), brown, covered with fine, short, pallid hairs ( Figs 6 View FIGURE 6 A, C). Surrounding of eyes almost black. Clypeus narrow, with numerous whitish setae, overhanging its ventral edge ( Fig. 6 View FIGURE 6 B). Chelicerae, endites and labium brown, anterior margins of endites and labium yellow. Sternum round, orange, clothed in fine, short and brown hairs. Abdomen cylindrical, yellow, with orange dorsal scutum (mostly discoloured, therefore colour pattern rather invisible), covered with sparse, brown hairs and mostly rubbed pale scales ( Figs 6 View FIGURE 6 A, D). Venter dark yellow. Spinnerets orange. Legs I brown, others orange with brownish femora. Pedipalps orange, tinted brown. Palpal organ as in Figs 6 View FIGURE 6 F –I.
