Diagnostic description.

Size: Total body length: 2.0 mm; fore wing length: 2.2 mm. Head: anterior scape colour moderately paler than head colour; F 2 L / W ratio: 3.2; F 14 L / W ratio: 1.4. Mesosoma: scutoscutellar sulcus with eight pits; mesoscutellar disc mostly smooth, or with very shallow scattered indentations; propodeal areola complete, or mostly so; propodeum mostly smooth posteriorly, mostly rugose anteriorly; coxae colour (pro, meso, meta): dark all; 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: 1.0. 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: 0.7.

Apanteles kelpiellus can be separated from the other described species of Apanteles known from Australia with a dark metacoxa by the metafemur mostly dark with pale area only in proximal 1 / 4, T 2 smooth, and the anterior side of scape moderately paler than head colour.

Etymology.

The species epithet means ‘ little kelpie’. A kelpie is a breed of dog in Australia commonly used as a sheepdog or companion animal. The epithet references the yellow anterior of the scape of the new species, which resembles the spots above a kelpie’s eyes. The epithet is a noun in apposition.

Distribution.

Apanteles kelpiellus is currently only known from northern QLD.

Molecular information.

Sequences of Apanteles kelpiellus are currently in BIN BOLD: ADL 3948. The COI sequences are at least 7 % divergent from any of the other species treated here, or any available sequence on BOLD. The wg sequence of the holotype is at least 5 bp different to any other species. Most delimitation methods resolved A. kelpiellus as a discrete species, however COI PTP split one of the paratypes apart, and wg PTP grouped the species with A. margaritarius .
