Stephens leg.; Malaise trap; exotic / native garden blend in pasture setting; BOLD Process ID: AUMIC 247-18; AM: K. 647409. Paratypes.

Pk.; - 35.3311, 138.747; 1–14 May. 2016; E. Fagan-Jeffries leg.; Malaise trap; BOLD Process ID: AUMIC 093-18; SAMA: 32-47778.
Diagnostic description.
Size: Total body length: 2.8 mm; fore wing length: 2.5 mm. Head: anterior scape colour similar or only very slightly paler than head colour; F 2 L / W ratio: 2.9; F 14 L / W ratio: 1.4. Mesosoma: scutoscutellar sulcus with seven pits; mesoscutellar disc punctate throughout; propodeal areola complete, or mostly so; propodeum mostly rugose; coxae colour (pro, meso, meta): all dark; metafemur colour mostly dark. Wings: centre of pterostigma pigmented to same degree as the outer edges; fore wing r vein length / 2 RS vein length ratio: 1.4. Metasoma: T 1 shape mostly parallel, T 1 medial length / anterior width between 1–2 × longer than wide; T 1 mostly rugose; T 2 mostly smooth; ovipositor sheath length / metatibia length ratio: 1.0.
Apanteles adustus can be separated from the other species of Apanteles in Australia that have a dark metacoxa and metafemur, ovipositor sheaths> 0.6 × metatibia length, antennae of similar size or longer than the length of the body, a completely hyaline fore wing membrane, and a uniformly pigmented pterostigma (no paler centre region, and no pale spot on proximal corner), by having T 1 with strong rugose sculpture over most of length, the mesoscutellar disc punctate throughout, T 3 densely setose, and T 2 posterior width / medial length ratio ~ 2.6.
Etymology.
The species epithet is a Latin adjective meaning ‘ singed / burnt’ and is inspired by the dark colouration, particularly the two-tone metatibia.
Distribution.
Apanteles adustus is currently known from two sites, one in NSW and one in SA.
Molecular information.
Apanteles adustus is currently represented by sequences in BIN BOLD: ADL 3155. The COI sequences are at least 5 % divergent from any of the other species treated here, or any available sequence on BOLD. The wg sequence of the holotype is ≥ 19 bp different to any other species. All molecular species delimitation methods separated Apanteles adustus as a distinct species.
