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 View FIGURES 64 – 71 ) and fore wing (without speculum and without hyaline break on parastigma, Fig. 71 View FIGURES 64 – 71 ), position of the toruli (with their lower margins at most slightly higher than the lower margins of the eyes, Fig. 64 View FIGURES 64 – 71 ), and colour (only head with distinct metallic reflections, Figs 61–63 View FIGURES 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 View FIGURES 64 – 71 ). Scape almost reaching lower margin of median ocellus ( Fig. 64 View FIGURES 64 – 71 ). Gena conspicuously depressed at mouth corner ( Fig. 66 View FIGURES 64 – 71 ), posterior margin carinate.

Gaster. Ovate, from about equal to slightly longer than head plus mesosoma ( Figs 61, 62 View FIGURES 61 – 63 ); 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 View FIGURES 64 – 71 ). Dorsal side of mesosoma orange to partly or almost entirely metallic green. Wing venation yellowish. Scape with ventral protuberance towards apex ( Fig. 67 View FIGURES 64 – 71 ); anelli longer, especially the third ( Fig. 67 View FIGURES 64 – 71 ). Head less transverse in dorsal view. Genae larger and shinier ( Fig. 63 View FIGURES 61 – 63 ). Eyes smaller ( Fig. 63 View FIGURES 61 – 63 ), hence malar space, as well as temples in dorsal view longer. Gaster shorter than head plus mesosoma ( Fig. 63 View FIGURES 61 – 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 View FIGURES 61 – 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.
