( Figs 61–71 ) Diagnosis. Both sexes : head always with metallic reflections, mesosoma usually orange-brown ( Figs 61–63 ); lower margin of toruli level with or only slightly above lower margins of eyes ( Fig. 64 ); antenna with funicular segments not pedicellate ( Fig. 66 ); gena depressed at mouth corner ( Fig. 66 ); inner margins of eyes not sinuate ( Fig. 64 ); POL about equal to OOL; mandibular formula 3:2; pronotum not visible in dorsal view ( Fig. 68 ); notauli visible throughout length of mesoscutum ( Fig. 68 ); prepectus and dorsal side of propodeum bare ( Figs 69, 70 ); axillae wide apart ( Fig. 68 ); posterior margin of mesoscutellum not densely setose, without distinct spine ( Fig. 68 ); anterior margin of propodeum not distinctly raised, not concealing dorsellum ( Fig. 70 ); propodeal plicae posteriorly converging ( Fig. 70 ); mesopleuron mostly finely reticulate, femoral depression almost indistinct, without central pit ( Fig. 69 ); fore wing ( Fig. 71 ) narrow, length 2.2–2.4× width, without speculum; parastigma without hyaline break; body size: 0.8–1.4 mm . Austroterobia partiviridis most closely resembles A . partibrunnea , from which it can be separated mainly by structure of the mesopleuron (without deep central pit, Fig. 69 ) and fore wing (without speculum and without hyaline break on parastigma, Fig. 71 ), position of the toruli (with their lower margins at most slightly higher than the lower margins of the eyes, Fig. 64 ), and colour (only head with distinct metallic reflections, Figs 61–63 ).

Structure. Head. Toruli closer to ventral margin of clypeus than to median ocellus, their lower margins about level with lower margins of eyes ( Fig. 64 ). Scape almost reaching lower margin of median ocellus ( Fig. 64 ). Gena conspicuously depressed at mouth corner ( Fig. 66 ), posterior margin carinate. Malar sulcus absent ( Fig. 66 ). Eyes from almost round to broad oval, inner margins not sinuate in middle and slightly divergent in lower part ( Fig. 64 ). Funicular segments not pedicellate ( Fig. 66 ). Head width 2.2–2.4× length (51:21) in dorsal view and about 1.4× height (51:37) in frontal view. POL 1.15× OOL (11.5:10.0). Eye height about 1.2× length (20:17), 1.1–1.4× malar space (20:14), and about 1.1× scape length (20:18). Head width 1.0–1.2× length of pedicel plus flagellum (51:41). F1 width about 1.1× length (4.0:3.5); F5 width 1.25× length (5:4); clava length 2.2–2.6× width (11:5). Mesosoma. Dorsally setose except metanotum and median area of propodeum ( Fig. 68 ); prepectus and metapleuron bare ( Fig. 69 ); mesopleuron bare except for some setae on lower mesepisternum ( Fig. 69 ). Pronotum barely visible in dorsal view ( Fig. 68 ). Notauli complete ( Fig. 68 ). Axillae wide apart, medially connected by moderately wide groove separating mesoscutum from mesoscutellum ( Fig. 68 ). Posterior margin of mesoscutellum evenly curved ( Fig. 68 ). Anterior margin of propodeum not distinctly raised, not concealing dorsellum ( Fig. 70 ). Propodeum with straight, complete median carina and almost complete plicae, the latter slightly converging posteriorly ( Fig. 70 ). Fore wing ( Fig. 71 ) completely setose, without speculum; parastigma without hyaline break; marginal vein moderately thickened. Mesosoma length subequal to width (42:41), width about 1.5× height (41:28). Mesoscutum width about 2.7× length (41:15). Mesoscutellum length 0.9× width (20:22). Propodeum length 0.5× mesoscutellum length (10:20). Fore wing length about 2.4× width (100:42); MV equal to SV (16:16); PV 1.75–2.0× MV (28:16). Gaster. Ovate, from about equal to slightly longer than head plus mesosoma ( Figs 61, 62 ); length 1.4–1.7× width (65:45). Male . Differs from the female mainly as follows. Body length: 0.9–1.0 mm. Dorsal side of pedicel and flagellum only slightly darker than scape ( Fig. 67 ). Dorsal side of mesosoma orange to partly or almost entirely metallic green. Wing venation yellowish. Scape with ventral protuberance towards apex ( Fig. 67 ); anelli longer, especially the third ( Fig. 67 ). Head less transverse in dorsal view. Genae larger and shinier ( Fig. 63 ). Eyes smaller ( Fig. 63 ), hence malar space, as well as temples in dorsal view longer. Gaster shorter than head plus mesosoma ( Fig. 63 ). Head width about 2.2× length in dorsal view and width about 1.3× height in frontal view. Eye height about 1.1× length and about subequal to malar space. F1 length 1.00–1.25× width; F5 quadrate; clava length 3.0–3.3× width. Mesosoma length about 1.1× width, width about 1.4× height. Mesoscutum width about 3× length. Mesoscutellum length equal to width. Fore wing length 2.2–2.4× width; MV about 1.1× SV. Gaster from about as long as head plus mesosoma to shorter than mesosoma, usually strongly collapsed dorsally or laterally, length 1.3–1.7× width ( Fig. 63 ). Distribution. Australia . Biology. Unknown. Remarks. A male identified as A . partibrunnea by Z. Bouček has the mesosoma dorsally distinctly metallic green. This specimen also has a darker gaster, orange-brown basally and dark brown distally. However, it has all the other characters of the new species, so it is included in the type series. One female specimen lacking its head is excluded from the type series. Etymology. The specific epithet indicates that in this species only the head is metallic green.
