Some details of the males can be determined from the photographs in the CDBD (Chironomid DNA Barcode Database), since those specimens are placed in the same BOLD Bin.
Color dark brownish black, legs yellowish, but darkening on tarsi; but some specimens have a yellowish base color of the thorax and more dull green on abdominal segments I-VII, but posterior end of segment VII, and segments VIII and IX almost black. Mid F/T about 1.1; Hind LR about 0.7, F/T about 0.9-0.94.
Fourth instar larva: No details of the larva are available, as the specimen from which the DNA sequence was obtained was probably destroyed in the process. However, in general morphology it was similar to that of species 3, i.e. one pair of ventral tubules.
