Calypter yellowish with dense darkish brown microtrichae, margin with brownish setulae.
Wing: Base fuscous, basicosta black; costa setulose only basally on ventral surface; costal spine shorter than cross-vein r-m; radial node bare, calypters brown; lower calypter slightly shorter than upper one; halter yellow.
It unquestionably belongs to the calyptrate family Anthomyiidae because of the following combination of characters: (1) head holoptic in male, dichoptic in female; (2) female with a pair of crossed interfrontal setae; (3) lower calypter well developed; (4) tiny hair-like setulae present beneath tip of scutellum; (5) vein A1 extended to wing margin as a weak fold; (6) male surstyli and cerci united by vertical sclerotized connections immediately distal to lateral cercal apodemes; (7) spiracles VI and VII present in female abdomen.
Anterior katepisternal seta present; lower calypter not broad and truncated, tongues-haped, of the Phaonia-type (see couplet 6 for description); [R.
Base slightly brown; basicosta black, without costal spine, both surfaces of radial node with setae, m-m crossvein S-shaped, calypteres dark brown, lower calypter with small lobule, inside it with few setae in the middle; with anterior paracalyptral tuft, but without posterior paracalyptral tuft; halteres brownish-yellow.
Upper calypter long black ciliate, longest ciliae as long as alula width.

Some eggs were situated in unusual body parts, difficult to access, such as the ventral part of the abdomen and between the two calypters (Figs 5-7).
The member of the family can be recognized by the following combination of characters: lower calypters glossiform or ovate, diverging from scutellum; posterior spiracle triangular without a distinct operculum, with both anterior and posterior fringes reduced; subscutellum distinctly developed, but not strongly developed as in Tachinidae.
