[The cestode fauna of the fam. Hymenolepididae in the anatine birds of Chukotka. The genus Dicranotaenia].
There are 5 species of the genus Dicranotaenia recorded in the North-west of Chukotka: Dicranotaenia coronula (?) (Dujardin, 1845), D. fallax (Krabbe, 1869), D. parvisaccata (Shepard, 1943), D. sacciperum (Mayhew, 1925) and D. clangulae sp. n. Brief characteristic of the new species. Rostellar hooks 24-28, their total length 17-20 mkm, blade 10-12 mkm, guard processus 7-9 mkm, basis 13-15 mkm. Blade is parallel to basis, significantly longer than guard processus, hook form of aploparaksoid type. Cirrus pouch with s-like bend and distal enlargement (as in D. fallax). Cirrus almost cylindrical, 115-136 mkm in length, diameter at base 20-23 mkm, distal diameter 13-16 mkm. Internal acessory sac (SAI) situated anterior and dorsal from base of cirrus, gradually attenuate to distal end, length of SAI 27-30, diameter at base 30-32. Descriptions of adult forms and metacestodes of four other species are given.
