The anterior 1/3 of the pronotum is much darker than the posterior 2/3 ( Figs 7A, 7C ). The gills consist of triple filaments ( Fig. 7B ). The hind femora bear secondary setae; there are no secondary setae on middle femora ( Figs 7D, 7E ). The cases are straight cylinders up to 2 cm long ( Fig. 7F ). The cases are mainly composed of parts of water moss stems and leaves with some parts of stems of vascular plants mounted at right angles to the longitudinal axis of the case. This species is minor in number, sporadically occurring in the Trichoptera assemblages on water moss.
