RECOGNITION.– Pison nogorombu is an all black species, with three submarginal cells, the second recurrent vein interstitial with the second intersubmarginal vein, and abundant erect setae on the head, thorax, propodeum, and gastral segment I (most setae 3 × as long as midocellar width). It can be recognized by a mandible with the posterior margin stepped and straight between the base and the step (Figs. 1240, 1241), and by the forewing asetose basally (Fig. 1244). Subsidiary recognition features are: propodeum all unridged, with well-defined punctures that average more than one diameter apart (Fig. 1243), without carina separating side from dorsum and posterior surface, and in the male: free margin of clypeal lamella obtusely tridentate (1238), flagellomeres IV and V emarginate basoventrally (Fig. 1246), bottom of emarginations longitudinally microridged.

DESCRIPTION.– Frons dull, punctures well defined to inconspicuous, averaging several diameters apart, interspaces markedly microareolate (Fig. 1239). Posterior mandibular margin step-like, straight between base and step (Figs. 1240, 1241). Gena narrow in dorsal view. Labrum not emarginate. Anteromedian pronotal pit transversely elongate, about twice as long as midocellar diameter. Scutum not foveate along flange, with short longitudinal ridges adjacent to posterior margin; scutal punctures well defined, averaging several diameters apart; interspaces microareolate (Fig. 1242). Tegula slightly enlarged. Mesopleural punctures well defined, averaging about one diameter apart dorsally, more than one diameter apart ventrally. Postspiracular carina present, about as long as midocellar diameter. Metapleural sulcus inconspicuously costulate between dorsal and ventral metapleural pits. Propodeum without longitudinal carina separating side from dorsum and concealing integument on clypeus; setae on lower frons practically straight. Apical depressions of terga without silvery, setal fasciae.

Body all black.

♀.– Upper interocular distance equal to 0.50 × lower interocular distance; ocellocular distance equal to 0.8 × hindocellar diameter, distance between hindocelli equal to 0.8 × hindocellar diameter; eye height equal to 1.06 × distance between eye notches. Free margin of clypeal lamella roundly prominent (Fig. 1237). Dorsal length of flagellomere I 3.1-3.2 × apical width, of flagellomere IX 1.6 × apical width. Mandible: trimmal carina with small incision at about two thirds of length. Length 10.0- 10.5 mm; head width 2.7-3.0 mm.

♂.– Upper interocular distance equal to 0.60 × lower interocular distance; ocellocular distance equal to 1.1 × hindocellar diameter, distance between hindocelli equal to 0.8 × hindocellar diameter; eye height equal to 1.06 × distance between eye notches. Free margin of clypeal lamella obtusely tridentate (Fig. 1238). Flagellomeres IV and V emarginate basoventrally (Fig. 1246), bottom of emargination longitudinally microridged. Dorsal length of flagellomere I 2.6-3.0 × apical width, of flagellomere X 1.4 × apical width. Sternum VIII shallowly, broadly emarginate apically (Fig. 1247). Genitalia: Figs. 1248, 1249. Length 9.0-10.0 mm; head width 2.4-2.9 mm.
