Diagnostic description.

Size: Total body length: 2.1 mm; fore wing length: 2.2 mm. Head: anterior scape colour moderately paler than head colour; F 2 L / W ratio: 2.6; F 14 L / W ratio: 1.3. Mesosoma: scutoscutellar sulcus with 11 pits; mesoscutellar disc mostly smooth, or with very shallow scattered indentations; propodeal areola complete, or mostly so; propodeum mostly smooth; coxae colour (pro, meso, meta): pale, pale, dark; metafemur colour mostly pale. Wings: centre of pterostigma pigmented to same degree as the outer edges; fore wing r vein length / 2 RS vein length ratio: 0.8. Metasoma: T 1 shape mostly parallel, T 1 medial length / anterior width between 1–2 × longer than wide; mostly rugose; T 2 mostly smooth; ovipositor sheath length / metatibia length ratio: 1.0.

Apanteles auroralis can be separated from most other species of Apanteles in Australia with a dark metacoxa, a completely pale metafemur and a uniformly pigmented pterostigma by the ovipositor sheath 0.8–1.0 × metatibia length and hypopygium with clearly defined ventral pleats. The species can be separated from A. apricus by the propodeum comparatively smoother, areola clearly defined and T 1 parallel-sided; A. apricus has the propodeum with much stronger sculpturing and T 1 slightly narrowing posteriorly.

Etymology.

The species epithet is an adjective formed from the Latin noun aurora meaning dawn / sunrise and relates to the strong colour contrast between the two yellow pro- and mesocoxae, and the dark metacoxa.

Distribution.

Apanteles auroralis is known from two sites in southern QLD.

Molecular information.

Apanteles auroralis contains sequences currently in BIN BOLD: ADL 4428. The COI sequences are at least 11 % divergent from any of the other species treated here, or any available sequence on BOLD. The wg sequence of the holotype is ≥ 3 bp different to any other species. Whilst the four COI delimitation methods separated Apanteles auroralis as a distinct species, there are two wg haplotypes within the species (1 bp difference), and the wg ASAP and PTP analyses grouped A. auroralis with A. darthvaderi .
