Comb of segment VIII of 1-10 teeth (m=5.4, n=49), teeth short with swollen bases (149t.jpg). Lateral taeniae of segments V-VIII: 4,4(5),4,5.

Ecological notes
Stagnant water, extending into brackish habitats.
Larvae mine plants or inhabit the surface of living plants, occasionally found on sediments or hard surfaces, usually absent when pH drops below 5.0 (Moller Pillot et al., 1995a).
