Abstract

Two new species of <i>Cinclotaenia</i> (Cyclophyllidea: Dilepididae) are described from the small intestine of <i>Cinclus leucocephalus</i> (Aves: Passeriformes: Cinclidae) collected in the Yungas region of Bolivia. <i>Cinclotaenia minuta</i> n. sp. is characterized by possessing a minute strobila with a maximum body length of 1.58 mm, consisting of 5–10 proglottids, 19–22 rostellar hooks with lengths from 16 to 17 mm, 12–17 testes per proglottid, and eggs forming packets without filaments. <i>Cinclotaenia boliviensis</i> n. sp. has bandlike strobila with a length up to 26 mm with 67–74 proglittids, 22 rostellar hooks with length 39–42 mm, 43–68 testes, and eggs forming packets possessing long filaments. The systematic position in <i>Cinclotaenia</i> of cestodes lacking filaments on the egg packets is confirmed. This is the first record of species of <i>Cinclotaenia</i> in dippers from Bolivia and also the first report of cestodes from <i>Cinclus</i> sp. in the Neotropical Region.
