LECTOTYPE DESIGNATION.– Neither Le Guillou nor F. Smith mentioned the number of the specimens examined in their original descriptions of Pison peletieri and Pison ruficorne , respectively. I have designated as the lectotypes of these two species the only existing specimens in the Muséum National d’Histoire Naturelle, Paris, and The Natural History Museum, London, respectively. The two specimens are perfectly conspecific.

JUSTIFICATION OF NEW SYNONYMY.– In his key to the Australian Pison, Turner (1916b) erroneously placed Pison peletieri in the section of species with the second recurrent vein reaching the second submarginal cell near its apex, and not in the middle of the cell. Apparently he had not seen the type, and was probably misguided by Le Guillou’s imperfect statement “Cette espèce se rangera dans la division établie par M. Shuckard pour la Monographie des Pisons”, whereas the text would have been correctly “ … dans la division des Pisonitus établie par M. Shuckard pour la Monographie des Pisons”.

PUBLICATION DATE.– The volumes containing the descriptions of Pison peletieri and Pison pelletieri are both dated 1841, but the latter name was demonstrably published after 1 January 1842, as page LXXIV of volume 10 of the Annales de la Société Entomologique de France contains a list of “membres reçus depuis le 1 er Janvier 1842 ”. The only clue to the publication date of the Revue Zoologique par la Société Cuvierienne for 1841 are the minutes, on p. 389, of a meeting of 28 December 1841. Although unlikely, it is not impossible that the volume was published in 1841.

RECOGNITION.– Pison peletieri is characterized by the second recurrent vein received near the middle of the second submarginal cell, black thorax and propodeum, all or largely ferruginous gaster, and ferruginous tibiae. Unlike P. virosum , the distance between the antennal socket and adjacent orbit is equal to the socket width or smaller in P. peletieri (rather than about twice socket width), and the scutal flange is slightly projecting beyond the axilla’s anterior margin, with the posterior scutal margin slightly concave next to the apex of flange (rather than roundly curving into the anterior margin of the scutellum). Unlike P. deperditum , the episcrobal area is not rugose. Unlike P. orbitale , the eye emargination of P. peletieri is the usual size (rather than less than half midocellar diameter), the tegula is partly impunctate and only partly concealing the humeral plate (rather than all punctate, fully covering the humeral plate), and the thorax lacks the omalus and hypersternaulus (ill defined omalus and hypersternaulus present in orbitale ). Unlike the female of P. frontale (male unknown), the clypeal lobe is well differentiated (rather than not differentiated), and the frons is not swollen (rather than conspicuously swollen). Finally, P. peletieri differs from P. rufigaster in having finer, microscopically small punctures on the scutum and sternum II, and the free margin of the clypeal lamella truncate or nearly so in the female and in the male either with a median point or acutely to obtusely angulate (in P. rufigaster , the scutal and sternal punctures are fine but not microscopic, and the free margin of the clypeal lamella is roundly prominent in the female and roundly arcuate in the male).

DESCRIPTION.– Frons dull, minutely punctate, punctures less than one diameter apart. Labrum broadly, shallowly emarginate. Gena narrow in dorsal view ( Fig. 785 ). Anteromedian pronotal pit transversely elongate, about as long as midocellar diameter. Scutum not foveate along flange in most specimens, but foveolate in those from Western Australia and Papua New Guinea, not ridged sulcus. Metapleural sulcus well defined between dorsal and ventral metapleural pits, not costulate. Propodeum with irregular longitudinal carina separating side from dorsum and posterior face and extending from gastral socket area toward spiracle, with conspicuous transverse ridges emerging from carina on both inner and outer side; dorsum obliquely ridged; in some specimens with second, more median carina that is interrupted by ridges; side punctate or ridged (punctate between ridges); posterior surface ridged; all propodeal ridges markedly varying from fine to conspicuous. Second recurrent vein ending at middle of submarginal cell II ( Figs. 787, 788 ). Posteroventral forefemoral surface microscopically, closely punctate. Punctures of tergum I microscopically fine, averaging less than one diameter apart. Sternum II minutely, sparsely punctate, impunctate apicomesally.

Setae silvery (with golden tinge on clypeus in some specimens), appressed on gena, thorax, and forecoxal venter, on upper frons (between midfrontal carina and midocellus) suberect, orient- ed dorsally, shorter than midocellar diameter; nearly completely concealing integument on clypeus; not forming setal fasciae on apical depressions of terga.

Head, thorax, propodeum, and femora black (femora ferruginous in lectotype, partly so in specimens from Papua New Guinea), female clypeus ferruginous next to lobe free margin; mandible black basally, yellowish brown subbasally, ferruginous subapically, dark apically; antenna ferruginous (scape, pedicel, and apical flagellomeres dark dorsally in most specimens, apical flagellomere all dark in some specimens); tibiae, tarsi, and gaster reddish brown (tergum I nearly all black in lectotype and some other specimens).

♀.– Upper interocular distance equal to 0.80-0.86 × lower interocular distance; ocellocular distance equal to 0.5-0.6 × hindocellar diameter, distance between hindocelli equal to 0.9-1.0 ×

hindocellar diameter; eye height equal to 1.04-1.08 × distance between eye notches. Free margin of clypeal lamella truncate or with small, round median point ( Fig. 783 ). Dorsal length of flagellomere I 2.3-2.5 × apical width (2.9 × in lectotype of peletieri ), of flagellomere IX 1.1-1.2 × apical width. Mandible: trimmal carina with small notch at about one third of length. Length 6.2-7.7 mm; head width 1.8-2.1 mm

♂.– Upper interocular distance equal to 0.83-1.00 × lower interocular distance, ocellocular distance equal to 0.6-0.9 × hindocellar diameter, distance between hindocelli equal to 1.2 × hindocellar diameter; eye height equal to 1.06-1.13 × distance between eye notches. Free margin of clypeal lamella obtusely to acutely angulate or with median point ( Fig. 784 ). Dorsal length of flagellomere I 1.7 × apical width, of flagellomere X 1.0-1.9 × apical width. Sternum VIII shallowly, broadly emarginate ( Fig. 789 ). Genitalia: Figs. 790, 791 . Length 5.3-5.6 mm; head width 1.5-1.8 mm.

VARIATION.– In a specimen from Agnes Water, Queensland, the second submarginal cell is open in the ventral half on the distant side in the right wing, and totally reduced in the left wing (except for a minimal stub on the first intersubmarginal cell).
