NAME DERIVATION.– Incurvatus (neuter: incurvatum ) is a Latin perfect passive participle of the verb incurvare, meaning curved, bent; with reference to the shape of the female clypeus.
RECOGNITION.– Pison incurvatum has two submarginal cells, the second cell short (its posterior margin is 1.2-1.5 × height), the tegula finely punctate throughout and in some wing positions completely covering the humeral plate. The male is unknown. The female can be recognized by the unique shape of the clypeus whose lamella is bent posteriorly and forms an angle with the more dorsal part ( Figs. 537, 538 View FIGURES ). Unlike P. aberrans , the dorsal length of flagellomere II is 2.1 × the apical widh (rather than 1.3-1.6). Additionally, and in contrast to Pison bicellulare , the scutum has short longitudinal ridges adjacent to its hindmargin. The body is either nearly all black or (in specimens from Western Australia) the legs are ferruginous
DESCRIPTION.– Frons dull, microscopically finely punctate, punctures less than one diameter apart, middle supraantennal carina at most slightly longer than midocellar diameter (mostly short- er or absent). Distance between antennal socket and orbit slightly less than socket width. Occipital carina joining hypostomal carina. Gena narrow in dorsal view. Labrum with U-shaped emargination. Anteromedian pronotal pit transversely elongate, about 4 × as long as midocellar diameter. Scutum foveate along flange, with short longitudinal ridges adjacent to posterior margin, flange slightly extending beyond scutum posterior margin; scutal punctures minute, less than one diameter apart ( Fig. 539 View FIGURES ). Scutellum with foveate sulcus along anterior margin. Tegula enlarged, finely punctate throughout ( Fig. 539 View FIGURES ), fully covering humeral plate in some wing positions. Mesopleural punctures fine, averaging about one diameter apart near center; ill-defined omaulus present in some specimens. Postspiracular carina present, about twice as long as midocellar diameter; integument depressed between postspiracular carina and episternal sulcus. Metapleuron minutely punctate, metapleural sulcus not costulate between dorsal and ventral metapleural pits. Propodeum with irregular longitudinal carina separating side from dorsum and posterior surface and extending from gastral socket area toward spiracle; dorsum regularly obliquely ridged (transversely so in posteri- or half or so in some specimens), ridges becoming markedly larger near junction with longitudinal lateral carina, median sulcus absent in some specimens; side minutely punctate, in most specimens also ridged (at least anterodorsally); posterior surface with conspicuous, transverse ridges. Forewing with two submarginal cells; second submarginal cell short (length of posterior margin 1.2-1.5 × its height). Hindcoxal dorsum with outer margin obtusely carinate. Outer surface of hindtibia with evanescent spines. Punctures of tergum I minute, averaging about one diameter apart (some punctures up to two diameters apart). Sterna minutely punctate throughout.
Setae silvery, appressed on postocellar area, gena, thorax, forecoxal venter, femoral venters, and tergum I, variously oriented on upper frons (upper frons largely asetose in some specimens); largely concealing integument on clypeus. Apical depressions of terga with silvery, setal fasciae.
Body in most specimens black, mandible ferruginous mesally, mid- and hindtibial spurs black. In specimens from Western Australia the legs are all ferruginous and the mid- and hindtibial spurs are whitish.
♀.– Upper interocular distance equal to 0.95-0.97 × lower interocular distance; ocellocular distance equal to 0.7-0.8 × hindocellar diameter, distance between hindocelli equal to 1.2-1.3 × hindocellar diameter; eye height equal to 1.04-1.10 × distance between eye notches. Apical portion of clypeal lamella bent posteriorly, forming angle with more dorsal part ( Figs. 537, 538 View FIGURES ). Dorsal length of flagellomere I 2.1 × apical width, of flagellomere IX 0.9 × apical width. Mandible: trimmal carina with evanescent preapical tooth, with small incision at about two thirds of length. Length 4.5-6.3 mm; head width 1.1-1.6 mm.
♂.– Unknown.
