NAME DERIVATION.– Kalbarri is a town in western Australia (and also an aboriginal word of unknown meaning) near which the holotype was collected; a noun in apposition.

RECOGNITION.– Pison kalbarri is an all black species with three submarginal cells, the second recurrent vein interstitial with the second intersubmarginal vein, the tegula partly impunctate and asetose, and setae appressed on tergum I and sinuous, erect on the lower gena. Furthermore, it has no longitudinal carina separating the propodeal side from the dorsum and the posterior surface, the ocellocular distance in the female equals 0.8 × hindocellar diameter (the male is unknown), and the gastral setae are silvery. The female is strikingly similar to that of P. ovale , but differs in having the clypeal lamella not divided into a ventral and a dorsal part by a transverse sulcus.

DESCRIPTION.– Frons dull, punctate, punctures less than one diameter apart. Labrum not emarginate. Anteromedian pronotal pit transversely elongate, slightly shorter than midocellar diameter. Scutum not foveate along flange, without longitudinal ridges adjacent to posterior margin; scutal punctures well defined, less than one diameter apart; interspaces markedly microsculptured. Tegula slightly enlarged. Mesopleural punctures well defined, less than one diameter apart. Postspiracular carina evanescent, as long as midocellar diameter. Metapleural sulcus costulate between dorsal and ventral metapleural pits. Propodeum without longitudinal carina separating side from dorsum and posterior surface and extending from gastral socket area toward spiracle; dorsum obliquely ridged; side punctate, interspaces merging into minute ridges; posterior surface transversely ridged, punctate between ridges. Posteroventral forefemoral surface closely punctate. Punctures of tergum I about one diameter apart on horizontal part anterior to apical depression. Sterna punctate throughout, about two diameters apart on center of sternum II.

Setae silvery, appressed and also erect on upper frons (erect setae about as long as midocellar with), erect on postocellar area, appressed on scutum and tergum I; on lower gena erect, sinuous, up to 1.5 × midocellar diameter; not concealing integument on clypeus. Apical depressions of terga with silvery, setal fasciae.

Body all black, mandible dark reddish apically.

♀.– Upper interocular distance equal to 0.70 × lower interocular distance; ocellocular distance equal to 0.8 × hindocellar diameter, distance between hindocelli equal to 1.1-1.2 × hindocellar diameter; eye height equal to 0.92 × distance between eye notches. Free margin of clypeal lamella roundly triangular ( Fig. 555 ). Dorsal length of flagellomere I 1.8 × apical width in specimens from Western Australia), 2.2 × apical width in that from New South Wales, of flagellomere IX 1.1 × apical width. Mandible: trimmal carina with small incision at about apical two thirds. Length 7.0- 7.9 mm; head width 2.3-2.7 mm.

♂.– Unknown.
