LECTOTYPE DESIGNATION.– Smith (1869) did not give the number of specimens examined in the original description of Pison tibiale . I have designated as the lectotype of this species the only specimen present in The Natural History Museum, London, a male bearing a printed label “W. Australia ” and a handwritten label “ tibialis Sm. Type ”.

RECOGNITION. – Pison tibiale has a black gaster (apical depressions of terga brown) and abundant erect setae on the head, thorax, propodeum, and the basal half of tergum I. The female can be recognized by the clypeal lamella divided by an ill-defined, arcuate sulcus next to the free margin into dorsal and ventral portions (Fig. 1116), the ocellocular distance equal to 1.4-1.8 × hindocellar diameter, and in most specimens conspicuously punctate sternum II (Fig. 1117). The clypeal lamella is undivided in the other species with erect setae on tergum I except for P. tenuipunctatum (in which sternum II is minutely punctate) and to some extent in P. flagellarium (in which the ocellocular distance is about 0.9 × hindocellar diameter). Also, the tibiae are ferruginous in most P. tibiale , but black in the other two species. The male is distinctive in having a setose median sulcus on sternum VIII (Fig. 1118, 1119), the sternum surface otherwise largely unsculptured and asetose (except finely punctate and setose apically and laterally). A median sulcus on sternum VIII is also present in P. sulcatum in which the body setae are appressed.

DESCRIPTION.– Frons dull, punctures less than one diameter apart. Occipital carina joining hypostomal carina. Labrum slightly emarginate mesally. Anteromedian pronotal pit transversely elongate, about as long as midocellar diameter. Scutum not foveate along flange, without longitudinal ridges adjacent to posterior margin. Scutal and mesopleural punctures well defined, less than one diameter apart. Tegula slightly enlarged. Postspiracular carina absent. Metapleural sulcus not costulate to slightly costulate between dorsal and ventral metapleural pits. Propodeum with or without irregular longitudinal carina separating side from dorsum and posterior surface and extending from gastral socket area toward spiracle (carina ranging from absent to well defined); dorsum with well-defined punctures, interspaces merging into conspicuous, irregular, oblique ridges; sulcus with short, oblique carinae emerging from middle carina; side punctate, interspaces merging into irregular ridges; posterior surface punctate and irregularly transversely ridged. Posteroventral forefemoral surface with well-defined punctures that are about 1-2 diameters apart in female, about one diameter apart in male. Hindcoxal dorsum with outer margin sharply carinate (except basally). Hindfemur thickened apicodorsally, more so in male than in female. Punctures of tergum I less than one diameter apart adjacent to apical depression, up to several diameters apart on anterior declivity in female, averaging about one diameter apart in male. Sternum II coarsely punctate throughout in most specimens (Fig. 1117), finely punctate in some.

Setae silvery, erect on frons, thorax, propodeum, tergum I (except posteriorly), forecoxal venter, femoral venters, and male sterna; setae not obscuring integument on clypeus in female, obscuring in male; genal setae erect, sinuous. Setal length, expressed as a fraction of midocellar diameter, about 1.5 × on scutum anteriorly and tergum I, up to about 2.2 × on lower gena, at least 1.0 × on hindfemoral venter and male sternum II.

Head, thorax, propodeum, and gaster black, including antenna and mandible; apical depressions of terga brown (only apically on tergum I). Fore- and midfemora black (midfemur ferruginous apically in many specimens), hindfemur varying from all black (most specimens) to all ferruginous; tibiae and tarsi mostly ferruginous, but all legs black in specimens from Canberra, Australian Capital Territory; Gregory National Park, some from Keep River National Park, female from Groote Eylandt, Northern Territory; and Ban Ban Range, 4 km NE Batavia Downs, Cordalia State Forest, 2 km N Rokeby, and Watalgan Range, Queensland. Apical depressions of terga (including tergum II) with setal fasciae; fasciae silvery with golden tinge to golden.

♀.– Upper interocular distance equal to 0.80-0.84 × lower interocular distance; ocellocular distance equal to 1.4-1.8 × hindocellar diameter, distance between hindocelli equal to 1.1-1.3 × hindocellar diameter; eye height equal to 0.86-0.92 × distance between eye notches. Clypeal lamella narrowly arcuate, divided by ill-defined, arcuate sulcus next to free margin into dorsal and ventral portions; free margin obtusely angulate (Figs. 1115, 1116). Dorsal length of flagellomere I 2.3-2.4 × apical width, of flagellomere IX 1.3 × apical width. Mandible: trimmal carina with incision at about two thirds of length, proximal portion of incision forming well-defined tooth in some specimens. Tergum VI pointed apically. Length 8.4-9.6 mm; head width 2.8-3.2 mm.

♂.– Middle clypeal section conspicuously convex. Upper interocular distance equal to
