Hull, F.M. (1937) New species of exotic syrphid flies. Psyche 44, 12-32, pl. 2.
From original description (Hull 1937).
Head in profile not very long but extremely wide, practically twice as wide as thorax between the humeri. Occiput and vertex moderately developed, in nowise conspicuous. Front and face of average width. In profile the face bulges out below, much as in Rhopalosyrphus Gig.-Tos. Antennae quite elongate, the basoflagellomere quite wide and flat and about two and one-half times as long as the first joint. Eyes bare on either side opposite antennae with a curious narrow crease margined with grossly enlarged facets. This may be an abnormality, but as i t is perfectly symmetrical on both sides, it may be normal. Occipital fringe reduced to a single row of long collar like hairs, much as in Asarkina or Baccha. Abdomen extremely petiolate, the first tergum small, apparently completely fused with second tergum, at any rate the first and second terga together are nearly ten times as long as wide in the middle. The second tergum expands on its extreme posterior edge rather suddenly to some three or four times its narrowest width. Remaining terga fused into an oval bulging club. Scutellum quite short, broad and rounded, without spurs. Wings with a spur descending into R4+5. Angles of cells R4+5 and DM broadly rounded, without a trace of spurs.
