Dicosmoecus palatus McLachlan 1872 .

The protonum is uniformly grayish brown; the head and the legs are colored similarly (Fig. 4A). The spicules along the anterior edge of the pronotum are very short; relatively long setae are also present (Fig. 4B). Each tibia bears several pairs of light-colored spiked setae along the ventral edge (Fig. 4C). The cases are bulky, straight or very slightly curved tubes, constructed from relatively large pebbles; the dorsal part of the case is oval; the length of the case reaches 2.5 cm (Fig. 4D). Single individuals of this species regularly occurred in the assemblages of Trichoptera on water moss.
