Anabolia servata McLachlan 1880 .

The head is light-colored, with a contrasting V-shaped pattern of dark dots and merged spots against the yellowish background ( Figs 3A, 3B ). The side surfaces of middle and hind femora have additional secondary setae ( Figs 3C, 3D ). The secondary setae on the femora have no dark spots at their base ( Figs 3C, 3D ). The basal parts of the middle and hind trochanters each has a single ventral primary seta ( Figs 3 С, 3D). The larvae of this species are found in two types of cases shaped as straight or slightly conic tubes: one type consists of leaves of water moss, with a long plant detrital stick attached to some cases ( Fig. 3E ); the other type is made of mineral particles (sand) of different sizes, with a plant detrital stick mounted in each case ( Fig. 3F ). The occurrence of the second type is higher. The length of a case is no more than 2.5 cm. This species was minor in abundance but was regularly found in assemblages of Trichoptera on water moss.
