Figs. 72–73 , 95

Holotype (female): Indonesia: Papua, Z.-W. New Guinea, Boven–Digoel, 160km stroomop van Tanah Merah, 1 August– 30.ix.1929, W.G.N. v.d. Sleen . Holotype in Instituut voor Taxonomische Zoologie, Zoologisch Museum Amsterdam, Netherlands .

Specimen Examined (Paratype): 1 female, Indonesia: Papua, Z. New Guinea, 1912–13, Kloofbivak , 13.xi.1912, G. Versteeg ( ZMAN) .

Description. Fastigium verticis: eye length = 1.5: 2.1 mm; projecting 0.8 mm in front of eyes. Femora with the following number of spines on ventral margins: profemur 7–8 external, 6–7 internal; mesofemur 7 external, 3–4 internal; postfemur 14–16 external, 15–17 internal.

Female. Subgenital plate transverse, divided in midline by a narrow hyaline carina; resulting plates short but laterally prolonged and strongly curved dorsad, lateral surface sinuate; apex with a projecting, obtuse-triangular, membranous lobe (somewhat roof-shaped in the second female due to deformation during desiccation); transition between sclerotised plates and membranous apical lobe not well marked ( Figs. 72–73 ).

Coloration. Ochre. Frons concolorous, clypeus and dorsal part of labrum yellow; mandibles dark brown. Pronotum and legs marmorated. Tegmen ochre with little conspicuous brown spots. Postfemur with two medium brown spots in dorsal area and also hind knees medium brown. Female subgenital plate dark brown, midline and apical lobe pale. Ovipositor medium brown.

Measurements of female: body 28–32; pronotum 10.0–10.7; tegmen 46–47; postfemur 26.0–27.5; ovipositor 48–52; -height 3.0– 3.2 mm.

Diagnosis. P. uniformis is probably close to P. maculatus . The female subgenital plates are similar. However, the membranous apical area forms only a simply rounded apex instead of being faintly bilobate; the basal sclerites are without the strong lateral groove that is present in P. maculatus .

Etymology. The species is named for the uniform coloration.
