Diagnosis.
Female.
Pronotum about 2.1× as wide as long medially (
Fig. 4
); pronotum medially about 2/3 as long as mesoscutum (
Fig. 4
); ovipositor about 1.25× as long as body (
Fig. 1
).
Male.
Pronotum with lamella expanding anteriorly and laterally as thin roof and medial cleft absent (
Fig. 10
); all tarsi with basal four segments nearly equal in length and ta5 about 4× as long as ta4 (
Fig. 12
); head with submedian lines absent (
Fig. 8
). Spiracular process about 5.6× as long as basal width.
Description.
Female.
Head capsule, mesosoma and gaster with metallic tinge, predominantly green (
Figs 1–4
) with gaster dark green (
Fig. 6
). Eyes red and legs yellow (
Fig. 3
). Ovipositor valves yellow and sheaths black.
Head capsule uniformly micropunctate-reticulate (
Fig. 2
); in anterior view (
Fig. 2
) about 1.3× as wide as high medially; in lateral view (
Fig. 3
) about 1.4× as high as long; malar space about 0.56× eye height and 0.69× eye width. Antenna (
Fig. 3
) with scape and pedicel alutaceous; scape about 2.3× as long as wide, pedicel about 1.7× as long as apical width and about 1.2× as long as fu1; an1 about 4.5× and an2 about 2.4× as wide as long, and an2 about 1.9× as long as an1; flagellum with dense longitudinal sensilla a little longer than respective segment; funicle with fu1 as long as wide, fu1 about 1.6× as wide as an2, and all funiculars of nearly same size; clava about 2.7× as long as wide (
Fig. 3
). Clypeus and supraclypeal area not defined.
Mesosoma uniformly micropunctate-reticulate except propodeum with two symmetrical smooth and shiny oval areas (
Figs 1, 4
). Mesosoma (
Fig. 5
) with pronotum about 2.1× as wide as long medially and about 0.7× as long as mesoscutum; mesoscutum about 1.7× as wide as long medially with posterior margin of mid lobe as wide as anterior margin of scutellum; scutellum trapezoidal, with anterior width, posterior width and length in ratio of 17:21:17. Fore wing with marginal vein, postmarginal vein and stigmal vein in ratio of 15:11:12 (
Fig. 5
).
Gaster (
Fig. 6
) about 1.7× as long as wide medially; tergites smooth and shiny with irregular micropunctures except GT6 alutaceous. Ovipositor 1.25× as long as body.
Male.
Brown. Head capsule in dorsal view (
Fig. 8
) longitudinally striate-strigose and striate-punctate with sparse setae, about 1.5× as long as wide with anterior margin incurved medially; in lateral view about 2.4× as long as high (fig. 9). Antenna with scape strongly shortened and broad, about 1.2× as long as wide; pedicel triangular, below lamella of scape; fl1 flat, about 2× as long as wide; fl2 triangular with apex dull, about 1.7× as long as wide.
Pronotum (
Fig. 10
) as long as wide medially, longitudinally striate-strigose, with setae originating from shallow depressions; mesonotum (
Figs 10, 11
) micropunctate, about 1.4× as wide as long medially; metanotopropodeum (
Fig. 11
) about 1.3× as wide as long medially, longitudinally alutaceous-coriaceous except anterior margin oblique, with setae originating from shallow depressions. All tibiae, except for inner surfaces, with dense, stout, rounded spines, with maximal spine length about 1.1× as long as spiracular diameter on metanotopropodeum.
Gaster longitudinally striate-strigose; spiracular process about 5.6× as long as basal width.
Etymology.
The Latin word “
brevis
”, meaning “short”, in reference to the fact that females of
S. brevis
have a shorter ovipositor than
S. diutius
.
Biology.
Reared from the monoecious fig species,
F. orthoneura
.
