Author: (Meigen, 1830)

Exuviae 5.0-6.6mm long (m=5.5mm, n=14).
Cephalothorax: Thoracic horn 350-450µm long (m=386µm, n=17); ThR 3.2-5.2 (m=4.0, n=17). Plastron plate without a rim. Plastron plate 31-65x23-51µm (n=7). Plastron plate length 0.08-0.16 of horn length (n=18). Thoracic horn elongate, curved shortly after the base, more or less parallel-sided or widened towards apex, toothed. Plastron plate offset at horn apex, with or without a rim. Respiratory atrium thin-walled, half to three-quarters the lumen width, at most a little undulate marginally.
Abdomen: Anterior lateral taenia of segment VII at 0.38-0.50 of length segment VII (n=16). Anterior lateral taenia of segment VIII at 0.18-0.35 of length segment VIII (n=16).
Anal segment: Anal lobes toothed strongly both externally beyond the lateral taeniae and internally, both margins convexly narrowed to apex. Anal lobe ratio 2.8-3.9 (n=15). Insertion of anterior anal taenia at 0.27-0.4 of lobe length (n=16).
