Etymology We dedicate this species in honour of the late Dr John La Salle, hymenopterist, biodiversity researcher, director of the Atlas of Living Australia , and great friend to ADA.

Head, antenna and mesosoma dark, all tergites and most of metasoma dark, non sclerotised areas of T1–2 and anterior sternites paler; (fore-, mid-, hind coxa) dark, dark, dark; femora (fore-, mid-, hind femur) pale, light brown, dark; tibiae (fore-, mid-, hind tibia) pale, pale darkening distally, pale darkening distally or completely dark; tegula and humeral complex light brown to dark; pterostigma light brown to dark; fore wing veins light brown to dark. BODY LENGTH. Head to apex of metasoma: 2.3 (2.4) mm. HEAD. Antenna slightly shorter than body length; OOL/posterior ocellus diameter 1.7 (1.8); POL/ posterior ocellus diameter 2.1 (2.5); antennal flagellomere 2 length/width 2.4; antennal flagellomere 14 length/width 1.3. MESOSOMA. Anteromesoscutum reticulate rugose, finer in anterior half; number of pits in scutoscutellar sulcus 10 (11); scutellar disc with only shallow punctures; maximum height of mesoscutellum lunules/ maximum height of lateral face of mesoscutellum 0.7 (0.5). WINGS. Fore wing length 2.3 (2.7) mm; length of veins r/2RS 1.3; length of veins 2RS/2M 1.5 (1.2); length of veins 2M/(RS+M)b 0.8; pterostigma length/width 2.4. LEGS. Hind tibia inner spur length/metabasitarsus length 0.6. PROPODEUM. Relatively smooth, but with scattered carina and rugosity, particularly short carina radiating from posterior centre, and in posterior lateral corners. Medial carina indistinct. METASOMA. T1 length /T1 width at posterior margin 1.4 (1.3); parallel sided, mostly smooth with only shallow indistinct sculpturing; T2 width at posterior margin /T2 length 3.0 (2.7), rectangular with curved anterior corners, in paratypes more trapezoid shaped, mostly smooth, border with T3 indistinct in holotype , indented in paratypes ; T2 length / T3 length 0.8 (0.7); T3 sculpture smooth and shiny; ovipositor sheaths length/hind tibial length 0.3 (0.2).

Male As female but hind leg all dark, body longer ( 2.5 mm body length), 14 pits in the scutoscutellar sulcus, some variation in measurements including T1 length / T1 width at posterior margin 1.6, and notably the antenna lengthened: antennal flagellomere 2 length/width 2.8; antennal flagellomere 14 length/width 3.6. Distribution Currently only known from arid South Australia , in regions surrounding Lake Torrens. Host Unknown. Remarks This species constitutes the BIN BOLD:ADL2795, and is greater than 3% divergent from any other sequences available on the database.
