Description.

Wing length 1.9-2.1 mm (♂), 2.1-2.3 mm (♀). Length of ultimate section of vein M4 divided by penultimate section: 0.6-0.7. Eye height divided by gena height: 5.0-6.3. Gena angulate, highest near midpoint of eye. Clypeus broadly rounded. Fronto-orbital plate and ocellar triangle mostly ill-defined; ocellar triangle rounded anteriorly, extending to region between ors, subshiny. Fronto-orbital plate slightly visible to not visible when head viewed laterally; well-developed but relatively narrow compared to most congeners, slightly subshiny, setae slightly inset.

Chaetotaxy: Two ori; two ors. Orbital setulae in two irregular rows, erect to reclinate. Eye bare or with few minute, sparsely arranged hairs. Ocellar and postocellar setae well-developed, but thin. Two dorsocentral setae. Acrostichal setulae in eight irregular rows. Mid tibia with two posteromedial setae.

Colouration: Body, including halter, dark brown in base colour. Gena slightly pale. Notum greenish, sometimes becoming bluish anteriorly. Calypter margin and hairs brown. Abdomen metallic green, sometimes coppery.

Genitalia: (Figs 289-292 View Figures 289–292 ) Epandrium with small posterodistal spine. Surstylus small and rounded with tubercle-like setae clustered along inner and inner-marginal surfaces. Apex of hypandrium extremely elongate and tapered, subtriangular with base shallow and broadly arched; inner lobe attached to remainder of hypandrium by lightly sclerotised bridge. Metepiphallus broad and box-like with serrated ridges ventrally and irregular ridges laterally. Distiphallus separated from phallophorus by ~ 1.5 × height of basiphallus; mesophallus produced slightly past base of distiphallus; distiphallus small and ovate in ventral view with thin spinulose internal pads; distoventral plate vestigial, continuing as elongate, irregular duct that often has small, faint subapical sclerotised spot. Ejaculatory apodeme typical of Melanagromyza , blade relatively narrow and slightly pointed apically.
