Description.

Wing length 2.3-2.8 mm (♂), 2.5-3.0 mm (♀). Length of ultimate section of vein M4 divided by penultimate section: 0.9-1.2. Eye height divided by gena height: 4.3-5.0. Lunule higher than wide, smooth with broad, shallow pits, relatively well-sclerotised and sharply bent medially to follow curve of frons; with comparatively smooth, level interface with soft portion of frons.

Chaetotaxy: Two ori; two ors; length equal or decreasing anteriorly, or only with posterior seta long; often relatively short and straight, at least for ori, with length not exceeding width of soft portion of frons. One pair of prominent setae apically on each palpus.

Colouration: Setae dark brown. Frons light yellow to brownish with minute brown spots at base of fronto-orbitals and setulae; soft central region of frons with rows of dark pits that predominate towards lunule; back of head, first flagellomere, ocellar spot (larger than tubercle), clypeus, ventral margin of gena and palpus dark brown; postocellars on yellowish region; face mottled yellow, light brown and brown; pedicel, scape and ring around eye excluding venter of cheek brown; lunule brownish around base of antennae; lateral region of fronto-orbital plate narrowly brownish to orange with margin along eye sometimes brown, fading inwards to base of fronto-orbitals; central pitted region of gena light brown. Body dark brown with moderate greyish brown pruinosity; postpronotum light yellow with large anteromedial dark brown spot; notopleuron light yellow with small, lateral brown stripe; apex of fore femur light yellow for distance slightly more or less than width of femur apex; base of fore tibia light yellow; dorsal transverse carina on epandrium paler brown or yellowish. Halter light yellow. Calypter white.

Genitalia: (Figs 559-563 View Figures 559–563 ) Epandrium very flattened dorsally, further emphasizing large, unusual supra-anal process, which is thick, flat, shelf-like and nearly as wide as epandrium. Surstylus rounded, small, and with additional broad, flat inwardly (and slightly ventrally) directed lobe; cluster of tubercle-like setae on surstylus proper and inner lobe. Basiphallus ventrally fused to phallophorus; sclerotised along left lateral surface, dividing into one pair of bands on distal 1/2, one of which extends to left distal margin and again bifurcates, and one of which wraps around dorsum to right distal margin. Hypophallus with one pair of long plate-like sclerites that fade distally and are irregularly fused via ridges medially. Paraphalli directed laterally at base, then sharply angled towards venter at midpoint; right sclerite reduced. Mesophallus stem swollen at base (bulge exaggerated in lateral view) and distal 2/3 dorsoventrally compressed; with basal process in front of duct insertion and with small shallow bump ventromedially; apical chamber swollen, bilobed, mostly produced below stem. Distiphallus tubules S-shaped with basal curve smaller and not straightened at origin (apex more strongly curved in figure provided in Nowakowski 1973); basal 1/2 well-sclerotised, distal 1/2 mostly clear with small apical cup and single lateral band sclerotised. Ejaculatory apodeme well-developed with darker base and slightly darker margin; sperm pump with venter sclerotised.

Comments.

While Cerodontha (Poemyza) superciliosa has not been confirmed in the Delmarva states, Frick (1959) noted that he had seen specimens from "many of the States in the northern 1/2 of the United States", and it is thus included here. Characteristic of this species are light yellow shoulders and a light yellow, smooth (shallowly and gently textured) and medially angulate lunule that meets a similarly yellow frons that is darker, pitted, and softer anteriorly. The large, wide, and flat supra-anal process of the male is also highly characteristic.
