Diagnostic description.
Size: Total body length: 2.0 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: 2.8; F 14 L / W ratio: 1.4. 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): dark all; metafemur colour mostly dark. Wings: centre of pterostigma paler (more hyaline) than 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; T 1 mostly smooth; T 2 mostly smooth; ovipositor sheath length / metatibia length ratio: 0.6.
Apanteles fenestrinus can be separated from the other described species of Apanteles known from Australia with a dark metacoxa and metafemur and the pterostigma with outer border darker than centre, centre of pterostigma pale or transparent / hyaline by having the fore wing with veins M + CU, 1 cu-a, 1 M, 1 CUa, 1 CUb, (RS + M) a, 2 RS, and 1 m-cu all unpigmented, pale, or transparent and T 1 smooth.
Etymology.
The species epithet is an adjective formed from the Latin noun fenestra meaning window and relates to the hyaline centre of the pterostigma.
Distribution.
Apanteles fenestrinus is represented by very dispersed collection records in northern WA, northern SA, and TAS.
Molecular information.
Apanteles fenestrinus contains sequences currently in BIN BOLD: AFQ 4941. The COI sequences are at least 6.5 % divergent from any of the other species treated here, or any available sequence on BOLD. The wg sequence of the holotype is ≥ 5 bp different to any other species. The molecular delimitation methods other than COI PTP separated A. fenestrinus as a discrete species; COI PTP split the Western Australian specimens from the individuals from SA / TAS.
