Author: (Walker, 1856)

Exuviae 4.9-7.8mm long (m=6.4mm, n=46).
Cephalothorax: Cephalic tubercles conical, with an evenly swollen base. Thoracic horn much branched.
Abdomen: Hook row II entire, length of row 0.51-0.57x width tergite (n=5); hooks 93-102 (n=3). Armament of tergites II-VI in the form of an undivided, usually extensive patch of strong points, the points in each segment increasing in size posteriorly, but on VI the patch is more or less reduced. Antero-lateral points of tergites IV-VI small, usually much smaller than the median points. Sternites I and II or I-III with transverse rows of backwardly directed colourless spines. Comb of segment VIII of 1 (2-5) thorn(s). Lateral taeniae of segments V-VIII: 4,4,4,4(5).
Anal segment: Fringe of anal lobe with 35-75 taeniae (m=56, n=30).

Note: An unusual specimen from Bodensee in collection ZSM has the comb of segment VIII set on a projecting spur superficially resembling those of Chironomus, is most probably referable to this species.
