Diagnosis.

Austinicotesia papuanus body coloration is generally darker than that of A. indonesiensis (labrum, palpi and legs mostly dark brown to black) and by having wings slightly infumated. It also has anteromesoscutum punctures relatively sparser (separation between punctures 2.0-4.0 × puncture diameter), and the joining of veins r and 2Rs is not angulated.

Description.

Female. Body mostly dark brown to black (except for yellow-brown protarsus, ventral face of procoxa, and some apical segments of palpi); wings slightly infumated, with veins and pterostigma brown. Head with mouth relatively narrow, resulting in a relatively very large (but rather transverse) malar line. Face shiny but with sparse, uniformly distributed and shallow punctures. Distance between tentorial pits 0.4 × width of head at that same height. Labrum somewhat depressed. Mandibles relatively small. Glossa slightly elongate. Palpi elongate, reaching beyond pronotum when extended. Antenna heavily setose, setae relatively long. Pronotum enlarged dorsally, its median length (on a dorsal view) very large, much longer than width of flagellomeres, and clearly longer than propodeum in most Microgastrinae genera. Pronotum dorsally with a deep central notch and strong punctures on posterior margin. Pronotum laterally with only ventral groove present. Anteromesoscutum with deep punctures, each with one seta in the middle; separation between punctures 2.0-4.0 × puncture diameter. Propodeum with strongly defined and raised carinae, delimiting an areola (on posterior half) and a central carina (on anterior half), as well as transverse carinae that fork around spiracles. Fore wing without areolet, with vein 2RS much longer than vein r (but joining of both veins not angulated). Pterostigma relatively very thin, its length at least 3.5 × its maximum width. Hind wing with vein 2r-m absent. Hind wing with vannal lobe fully setose. Metacoxa relatively short, not surpassing posterior margin of T2. Metafemur relatively short (less than 1.3 × as long as metacoxa) and thick (its length 2.6-2.8 × its width). Metatibia spurs very short, less than 0.3 × length of first segment of metatarsus. T1 more or less parallel-sided, and with a strong hump centrally followed by a deep, excavated area which is delimited by strong carinae. T2 mostly smooth, with lateral margins well defined. T3+ entirely smooth. Hypopygium uniformly sclerotized. Ovipositor sheaths uniformly setose and clearly shorter than metatibia length. Body measurements (mm). F2 L: 0.19 (0.20-0.22); F3 L: 0.18 (0.21); F14 L: 0.08 (0.09-0.10); F15 L: 0.08 (0.09); Malar sulcus L: 0.04 (0.05-0.07); Mandible W: 0.07 (0.08-0.11); T1 L: 0.30 (0.32-0.35); T1 W at posterior margin: 0.14 (0.15-0.18); T1 maximum W: 0.14 (0.15-0.18); T2 W at anterior margin: 0.14 (0.16-0.20); T2 W at posterior margin: 0.27 (0.24-0.29); T2 L: 0.11 (0.09-0.16); Metafemur L: 0.50 (0.49-0.63); Metafemur W: 0.18 (0.19-0.23); Metatibia L: 0.69 (0.68-0.81); Inner spur L: 0.13 (0.12-0.16); Outer spur L: 0.09 (0.08-0.13); First segment of Metatarsus L: 0.32 (0.27-0.38); Ovipositor sheaths L: 0.33 (0.38-0.43); Body L: 1.76 (2.08-2.26); Fore wing L: 2.24 (2.22-2.60). Maximum W of T1 is taken at posterior margin of T1 where it is the largest for 4 specimens. T1 L is approximate for 1 specimen. One specimen has no head.
