Austroterobia achterbergi sp. nov.
( Figs 1–10 View FIGURES 1, 2 View FIGURES 3 – 10 )
Diagnosis. Female (male unknown): head at most with slight dark metallic reflections ( Fig. 1 View FIGURES 1, 2 ); legs yellowishbrown ( Fig. 1 View FIGURES 1, 2 ); inner margins of eyes very slightly sinuate ( Fig. 3 View FIGURES 3 – 10 ); gena conspicuously depressed at mouth corner ( Fig. 5 View FIGURES 3 – 10 ); POL about 0.7× OOL; toruli closer to median ocellus than to ventral margin of clypeus ( Fig. 5 View FIGURES 3 – 10 ); scape reaching slightly above lower margin of median ocellus ( Fig. 3 View FIGURES 3 – 10 ); basal two teeth of right mandible large and wide apart (cf. Fig. 13 View FIGURES 13 – 20 ); notauli visible only in anterior third of mesoscutum ( Fig. 7 View FIGURES 3 – 10 ); marginal vein more than 8× as long as broad ( Fig. 10 View FIGURES 3 – 10 ).
Due to the incomplete notauli, A. achterbergi most closely resembles A. maldica and A. heydoni , those being the only known species of the genus that display this feature. Of these, it is more similar to A. maldica , from which it differs mainly in having the POL shorter than the OOL ( Fig. 4 View FIGURES 3 – 10 ), a longer scape, and an indistinct malar sulcus ( Fig. 5 View FIGURES 3 – 10 ). Austroterobia achterbergi is also superficially similar to A gatesi , but this latter species has complete notauli ( Fig. 17 View FIGURES 13 – 20 ).

Description. Female. Body length: 1.5–1.8 mm.
Colour. Head dark brown to blackish, in the latter case with dark green metallic reflections ( Fig. 1 View FIGURES 1, 2 ). Dorsal side of mesosoma brown to dark brown except for lighter propodeum ( Fig. 7 View FIGURES 3 – 10 ); lateral side of mesosoma brown ( Fig. 8 View FIGURES 3 – 10 ). Gaster brown, lighter ventrally and basally on dorsal side ( Fig. 2 View FIGURES 1, 2 ). Eyes and ocelli whitish-grey ( Figs 3, 4 View FIGURES 3 – 10 ). Antenna ( Figs 5, 6 View FIGURES 3 – 10 ) with scape, pedicel, anelli and ventral side of funicular segments and clava yellowish-brown; dorsal side of funicular segments and clava brown. Mandibles pale yellow, teeth reddish-brown ( Figs 3, 5 View FIGURES 3 – 10 ). Legs entirely yellowish-brown except for darker pretarsi ( Fig. 1 View FIGURES 1, 2 ). Wings hyaline; tegula and venation light brown ( Fig. 10 View FIGURES 3 – 10 ). Body setation whitish, wing setation brown ( Figs 3, 7, 10 View FIGURES 3 – 10 ).
Sculpture. Head finely reticulate except for smooth clypeus ( Figs 3, 4 View FIGURES 3 – 10 ); malar region with sculpture denser ( Fig. 5 View FIGURES 3 – 10 ); mesoscutum and mesoscutellum reticulate, axillae almost smooth anterolaterally ( Fig. 7 View FIGURES 3 – 10 ); median area of propodeum, except median carina and plicae, extremely finely alutaceous, and with several superficial carinulae ( Fig. 9 View FIGURES 3 – 10 ); mesopleuron with shallow femoral depression and almost indistinct central pit ( Fig. 8 View FIGURES 3 – 10 ); prepectus, mesepimeron and metapleuron almost smooth ( Fig. 8 View FIGURES 3 – 10 ); upper mesepisternum alutaceous, lower mesepisternum very finely and densely reticulate ( Fig. 8 View FIGURES 3 – 10 ); gaster smooth.
Structure. Head. Toruli closer to median ocellus than to ventral margin of clypeus, their lower margins much higher than lower margins of eyes ( Fig. 5 View FIGURES 3 – 10 ). Scape surpassing lower margin of median ocellus ( Fig. 3 View FIGURES 3 – 10 ). Gena conspicuously depressed at mouth corner ( Fig. 5 View FIGURES 3 – 10 ), posterior margin carinate. Malar sulcus absent ( Fig. 5 View FIGURES 3 – 10 ). Eyes broad oval, inner margins slightly sinuate in middle and almost parallel in lower part ( Fig. 3 View FIGURES 3 – 10 ). Funicular segments slightly to distinctly pedicellate. Head width 2.3–2.5× length (60:24) in dorsal view and about 1.2× height (60:50) in frontal view. POL about 0.7× OOL (10:14). Eye height about 1.2× length (23:19), 1.35× malar space (23:17), and 1.10–1.35× scape length (23:17). Head width 0.9–1.1× length of pedicel plus flagellum (60:53). F1 width 0.9–1.2× length (7:6); F5 width 1.1–1.4× length (7:6); clava length 2.4–2.8× width (17:7).
Mesosoma. Dorsally setose, except metanotum and median area of propodeum ( Fig. 7 View FIGURES 3 – 10 ); prepectus and metapleuron bare ( Fig. 8 View FIGURES 3 – 10 ); mesopleuron bare except for some setae on lower mesepisternum ( Fig. 8 View FIGURES 3 – 10 ). Pronotum barely visible in dorsal view ( Fig. 7 View FIGURES 3 – 10 ). Notauli visible only in anterior third of mesoscutum ( Fig. 7 View FIGURES 3 – 10 ). Axillae wide apart, medially connected by wide groove separating mesoscutum from mesoscutellum ( Fig. 7 View FIGURES 3 – 10 ). Posterior margin of mesoscutellum evenly curved ( Fig. 7 View FIGURES 3 – 10 ). Anterior margin of propodeum not distinctly raised, not concealing dorsellum ( Fig. 9 View FIGURES 3 – 10 ). Propodeum with distinct median carina and posteriorly converging, almost complete plicae ( Fig. 9 View FIGURES 3 – 10 ). Fore wing ( Fig. 10 View FIGURES 3 – 10 ) with very small speculum, otherwise completely setose; parastigma without hyaline break; marginal vein hardly thickened. Mesosoma length subequal to width (55:52), width about 1.3× height (52:40). Mesoscutum width 2.4–2.6× length (52:20). Mesoscutellum length about 0.9× width (24:26). Propodeum length about 0.5× mesoscutellum length (13:24). Fore wing length 1.85–2.10× width (130:70); MV 1.2–1.4× SV (24:19); PV 1.4–1.6× MV (35:24).
Gaster. Wider in distal half, from about equal to slightly longer than head plus mesosoma ( Figs 1, 2 View FIGURES 1, 2 ); length 1.6–2.0× width (80:40).
