Austroterobia gatesi
sp. nov.
(
Figs 11–20
)
Diagnosis.
Female
(male unknown): head and mesosoma without metallic reflections (
Figs 11, 12
); inner margins of eyes very slightly sinuate (
Fig. 13
); gena depressed at mouth corner (
Fig. 15
); mandibular formula 3:2 (
Fig. 13
); antenna with funicular segments strongly pedicellate (
Fig. 16
); POL about 0.8× OOL; pronotum not or barely visible in dorsal view (
Fig. 17
); notauli visible throughout length of mesoscutum (
Fig. 17
); prepectus and dorsal side of propodeum bare (
Fig 17, 18
); axillae wide apart (
Fig. 17
); posterior margin of mesoscutellum not densely setose, without distinct spine (
Fig. 17
); anterior margin of propodeum not distinctly raised, not concealing dorsellum (
Fig. 19
); propodeal plicae present, converging posteriorly (
Fig. 19
); fore wing without speculum (
Fig. 20
); parastigma with hyaline break (
Fig. 20
).
Austroterobia gatesi
superficially resembles
A
. achterbergi
in colour, as well as in head and mesosomal structure; however it differs from the latter species in having complete notauli (
Fig. 17
), distinctly pedicellate funicular segments (
Fig. 16
), and a different wing structure, i.e. without a speculum and with a hyaline break on the parastigma (
Fig. 20
).

Description.
Female.
Body length:
1.4 mm
.
Colour.
Head and mesosoma dark brown (
Figs 11, 12
). Gaster light brown (
Figs 11, 12
). Eyes and ocelli whitish-grey (
Figs 13–15
). Antenna light brown (
Fig. 16
). Mandibles pale yellow, teeth reddish-brown (
Fig. 13
). Legs entirely yellowish except for darker pretarsi (
Fig. 11
). Wings hyaline (
Fig. 20
). Tegula and venation light brown (
Fig. 20
). Body setation whitish-brown, wing setation brown (
Figs 13, 17, 20
).
Sculpture.
Head coriaceous to alutaceous except for smooth clypeus (
Figs 13–15
); malar area with sculpture denser (
Fig. 15
); mesoscutum and mesoscutellum reticulate, axillae almost smooth (
Fig. 17
); median area of propodeum, except for median carina and plicae, almost smooth but with several superficial carinulae (
Fig. 19
); mesopleuron with shallow femoral depression, without any indication of a central pit (
Fig. 18
); prepectus, mesepimeron and metapleuron almost smooth (
Fig. 18
); upper mesepisternum alutaceous, lower mesepisternum finely reticulate (
Fig. 18
); gaster smooth.
Structure.
Head. Toruli about equidistant from median ocellus and ventral margin of clypeus, their lower margins much higher than lower margins of eyes (
Fig. 13
). Scape reaching lower margin of median ocellus (
Fig. 15
). Gena conspicuously depressed at mouth corner (
Fig. 15
), posterior margin carinate. Malar sulcus absent (
Fig. 15
). Eyes broad oval, inner margins slightly sinuate in middle and almost parallel in lower part (
Fig. 13
). Funicular segments strongly pedicellate (
Fig. 16
). Head width 2.5× length (50:20) in dorsal view and 1.25× height (50:40) in frontal view. POL about 0.8× OOL (9:11). Eye height 1.25× length (19.5:15.5), about 1.3× malar space (19.5:14.5), and 1.3× scape length (19.5:15.0). Head width subequal to length of pedicel plus flagellum (50:51). F1 width equal to length (5:5); F5 width 1.1× length (5.0:4.5); clava length 2.7× width (13.5:5.0).
FIGURES 11, 12.

, holotype ♀: 11, habitus, lateral view; 12, habitus, dorsal view.
Mesosoma. Dorsally setose, except for metanotum and median area of propodeum (
Fig. 17
); prepectus and metapleuron bare (
Fig. 18
); mesopleuron bare except for some setae along anteroventral margin (
Fig. 18
). Pronotum not visible in dorsal view (
Fig. 17
). Notauli complete (
Fig. 17
). Axillae wide apart, medially connected by wide groove separating mesoscutum from mesoscutellum (
Fig. 17
). Posterior margin of mesoscutellum evenly curved (
Fig. 17
). Anterior margin of propodeum not distinctly raised, not concealing dorsellum (
Fig. 19
). Propodeum with distinct median carina and posteriorly converging, almost complete plicae (
Fig. 19
). Fore wing (
Fig. 20
) completely setose, without speculum; parastigma with hyaline break; marginal vein hardly thickened.

Remarks.
This is the first record of the subfamily Austroterobiinae in the Neotropical region; it is highly probable that other species will be discovered when more material is examined.
Etymology.
Named in honour of Dr. Michael Gates (USNM), for his contribution to the systematics of
Chalcidoidea
