Diagnostic description.
Size: Total body length: 2.2 mm; fore wing length: 2.2 mm. Head: Anterior scape colour similar or only very slightly paler than head colour; F 2 L / W ratio: 3.1; F 14 L / W ratio: 1.2. Mesosoma: Scutoscutellar sulcus with 12 pits; mesoscutellar disc mostly smooth, or with very shallow scattered indentations; propodeal areola complete, or mostly so; propodeum mostly rugose; coxae colour (pro, meso, meta): dark all; metafemur completely dark; outer side of metatibia mostly dark with pale area in proximal 1 / 3. Wing: Fore wing membrane completely hyaline / transparent, without any trace of infuscation in the membrane. Centre of pterostigma pigmented to same degree as the outer edges; no large pale spot present on pterostigma; 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; T 1 mostly rugose; T 2 mostly smooth; T 3–6 with setae reduced to a single row on each tergite (exceptionally there may be a few extra setae laterally on some tergites but most setae are in a single row on each tergite); ovipositor sheath length / metatibia length ratio: 1.0.
Apanteles darthvaderi can be diagnosed from the other species with a dark metacoxa and metafemur, the outer side of metatibia mostly dark with a paler area in the proximal 1 / 3, an ovipositor> 0.6 × metatibia length, the pterostigma uniformly pigmented (no hyaline centre or large pale spot), and T 1 with rugose sculpturing, by the fore wing membrane completely hyaline (no infuscation) and T 3 – T 6 with setae mostly reduced to a single row on each tergite.
Etymology.
The species was named by students from Back Plains State School. The students named the species for a fictional character from the Star Wars space opera franchise, “ because this mean little wasp is from the dark side like Darth Vader, because it sucks the life out of the caterpillars. ” The species epithet is a noun in the genitive case.
Distribution.
Apanteles darthvaderi is currently known from along the east coast of Australia, from as far north as Townsville, as far south as Wonboyn, and as far inland as Canberra.
Molecular information.
Apanteles darthvaderi contains a single BIN (BOLD: AAU 8286). The COI sequences are at least 8 % divergent from any of the other species treated here, or any available sequence on BOLD. The species contains a single wg haplotype which is ≥ 3 bp different to any other species. We consider A. darthvaderi a well-supported species, with 5 / 7 congruent molecular delimitation methods. PTP and ASAP using wg grouped the species with A. auroralis, but as there are clear morphological differences (A. darthvaderi has the metafemur dark, A. auroralis has the metafemur completely pale), we believe these methods were too conservative in this case.
Remarks.
Apanteles darthvaderi closely resembles A. persephone and runs to the same couplet in the key if A. persephone is treated as having the metatibia mostly dark. We do not have a strong morphological character to separate these species, but also hesitate to identify the specimens here as A. persephone. Apanteles persephone was described from two specimens collected from near Perth in Western Australia, whilst A. darthvaderi is only currently known from the east coast. We have decided to describe A. darthvaderi as new based on this geographic disparity, but note that DNA sequencing of the type material of A. persephone, or at minimum sequencing a matching specimen from near the type locality, would resolve these two species more confidently.
