Pison aberrans Turner, 1908:519 , ♂. Lectotype: ♂, Australia: Queensland: Mackay (BMNH), present designation, examined. – Turner, 1908:458 (figure of forewing), 1916b:596 (in key to Australian Pison ), 601 (diagnostic characters); R. Bohart and Menke, 1976:335 (in checklist of world Sphecidae ); Cardale, 1985:257 (in catalog of Australian Sphecidae ).
LECTOTYPE DESIGNATION. – Turner (1908) did not mention the number of specimens upon which he based his description of Pison aberrans . I have selected as the lectotype the only specimen present in The Natural History, London, that bears the label “ Pison aberrans Turner , Type” in Turner’s handwriting.
RECOGNITION.– Pison aberrans is a small species (length 3.5-4.2. mm), with only two submarginal cells (exceptionally one), the posterior margin of the second one being equal to 0.7-1.4 × its height. It is further characterized by the head, thorax, gaster, and femora all black, the head in many specimens subspherical in the dorsal view, the clypeus with a prominent lobe mesally, the ocellocular distance smaller than the distance between the hindocelli, the tegula completely covering the humeral plate or nearly so, the presence, on the propodeum, of a longitudinal carina separating the side from the dorsum and the posterior surface and extending from the gastral socket area toward the spiracle, and the tibiae all or predominantly black. It differs from similar species in having asetose eyes, the tegula minutely punctate throughout or exceptionally impunctate and asetose posterolaterally, the mesopleuron without an omalus, the integument depreseed between the postspiracular carina and the episternal sulcus, and the propodeal dorsum coarsely ridged or rugose, at least near the median sulcus (rather than finely microareolate or finely regularly ridged). The yellowish brown tarsi of many males are subsidiary recognition features, as is male sternum VIII with two apical setae that protrude beyond the sternum apical margin. Unlike P. incurvatum (whose male is unknown), the clypeal lamella is in about the same plane as the more dorsal portion (rather than bent posteriorly, forming an angle with the more dorsal part), and the dorsal length of flagellomere I 1.3-1.6 × its apical width in the female, 1.0-1.4 × in the male (rather than 2.1 × in the female).
DESCRIPTION.– Head in many specimens subspherical in dorsal view. Frons dull, minutely punctate, punctures less than one diameter apart, middle supraantennal carina absent or evanescent. Distance between antennal socket and orbit about equal to socket width. Gena narrow in dorsal and asetose posterolaterally (as in holotype), fully concealing humeral plate or nearly so. Mesopleuron finely punctate, punctures averaging about one diameter apart; postspiracular carina present, integument depressed between postspiracular carina and episternal sulcus. Postspiracular carina present, about half as long as midocellar diameter. Metapleural sulcus not costulate between dorsal and ventral metapleural pits. Propodeum with longitudinal carina separating side from dorsum and posterior surface and extending from gastral socket area toward spiracle; dorsum obliquely ridged (ridges fine to conspicuous) or rugose, punctate between ridges; side punctate, interspaces merging into ridges; posterior surface ridged. Forewing with two submarginal cells ( Fig. 7 View FIGURES ), second submarginal cell absent in the right wing of holotype ( Fig. 8 View FIGURES ); posterior margin of second submarginal cell about 0.7-1.4 × its height. Punctures of tergum I on horizontal portion in most specimens less than one diameter apart, but more than one diameter apart in some. Sterna punctate throughout.
Setae silvery, appressed on head, thorax, forecoxal venter, femoral venters, and tergum I; frontal setae oriented dorsally (oriented ventrally adjacent to eye margin). Apical depressions of terga with silvery, setal fasciae.
Head, thorax, propodeum, and gaster black, mandible yellowish reddish except black basally and dark apically; antenna all black or flagellum ferruginous ventrally. Legs all black in most females and some males, but fore- and midtibiae, base of hindtibia, and tarsi yellowish brown in some females; tarsi (all or most) yellowish brown in most males; mid- and hindtibial spurs whitish in most specimens, but brown in some.
♀.– Upper interocular distance equal to 1.06-1.10 × lower interocular distance; ocellocular distance equal to 0.5-1.1 × hindocellar diameter, distance between hindocelli equal to 1.5-1.8 ×
hindocellar diameter; eye height equal to 0.92-1.04 × distance between eye notches. Free margin of clypeal lamella varying from arcuate to obtusely tridentate, with lateral teeth either well defined (as in Fig. 5 View FIGURES ) or inconspicuous, in many specimens separated by transverse carina from remaining clypeal surface. Dorsal length of flagellomere I 1.3-1.6 × apical width, of flagellomere IX 0.7 × apical width. Mandible: trimmal carina with small incision at about two thirds of length. Length 3.5-4.2 mm; head width 1.0- 1.1 mm
♂.– Upper interocular distance equal to 0.90-1.00 × lower interocular distance; ocellocular distance equal to 0.6-1.0 × hindocellar diameter, distance between hindocelli equal to 1.1-1.7 × hindocellar diameter; eye height equal to 0.78-1.02 × distance between eye notches. Free margin of clypeal lamella arcuate to obtusely tridentate ( Fig. 6 View FIGURES ), middle tooth widest, markedly larger than lateral tooth in some specimens. Dorsal length of flagellomere I 1.0-1.4 × apical width, of flagellomere X 0.7-0.8 ×. Sternum VIII broadly emarginate ( Fig. 9 View FIGURES ), with pair of apical setae that are up to about 1.5 × as long as midocellar diameter and protrude beyond sternal margin. Genitalia: Figs. 10 and 11 View FIGURES . Length 3.8-5.0 mm; head width 1.0- 1.3 mm.
