Diagnosis
Cotesia lasallei
sp. nov.
can be separated from all other species of
Cotesia
currently described from
Australia
and
Papua New Guinea
by the following combination of characters: Antennal flagellomere 14 length/width <
1.5 in
females, clearly shorter than most other species; fore wing
r vein
straight; T1 parallel sided, T1–2 mostly smooth; T2 with indistinct or shallowly indented border with T3; T3 dark with sparse setae over most of tergite; anteromesoscutum reticulate rugose; scultellar disk smooth with only shallow punctures; centre of medial posterior band of the scutellum (directly posterior to scutellar disk) smooth; fore wing 2RS not creating a ‘stub’ at junction with r.
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.

Description
Female
COLOUR. 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).

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.

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.
