Diagnostic description.

Size: Total body length: 2.7 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: 1.3. Mesosoma: scutoscutellar sulcus with ten pits; mesoscutellar disc punctate throughout; propodeal areola complete, or mostly so; propodeum mostly rugose; coxae colour (pro, meso, meta): dark all; metafemur colour mostly Pale with dark band in distal 1 / 3. 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 narrow,> 2 × longer than wide; T 1 mostly rugose; T 2 mostly smooth; ovipositor sheath length / metatibia length ratio: 1.0.

Apanteles aurantius can be separated from other species of Apanteles in Australia by the distinctive colouration of the metafemur (mostly pale / orange with a dark area distally).

Etymology.

The species epithet is a Latin adjective meaning ‘ orange’ and refers to the bright orange colour on the metafemur and metatibia.

Distribution.

Apanteles aurantius has a broad distribution, with collection records down the east coast of Australia, and isolated records in SA and WA.

Molecular information.

Apanteles aurantius contains sequences currently in BIN BOLD: AAG 8155. The COI sequences are at least 10 % divergent from any of the other species treated here, or any available sequence on BOLD. The wg sequence of the holotype is ≥ 7 bp different to any other species. All molecular species delimitation methods separated Apanteles aurantius as a distinct species.
