Trois Nadejdolepis Spasskii & Spasskaya, 1954 (Cestoda: Hymenolepididae) parasites de Charadrii (Aves) du Bélize

Three Nadejdolepis from Belize, Central America, represent new geographical records (1) Nadejdolepis paranitidulans (Golikova, 1959) (rostellar hooks 40-44 μm long) from Charadrius alexandrinus; (2) N. arenariae (Cabot, 1969) n. comb. (rostellar hooks 89 μm long) from Arenaria interpres; and (3) N. litoralis (Webster, 1947) (rostellar hooks 81-85 μm long) from Calidris fuscicollis (new host record). Additional descriptions, illustrations and information pertaining to these species are included. In addition, N. saguei Rysavy, 1967 is considered a synonym of N. litoralis (Webster, 1947). N. morenoi Rysavy, 1967 (rostral hooks 80 μm long) needs to be redescribed to confirm its validity. Two species of Nadejdolepis are transferred to the genus Microsomacanthus Lopez-Neyra, 1942 because their rostellar hooks are more diorchoid than nitiduloid, becoming M. cambrensis (Davies, 1939) n. comb. and M. alaskensis (Deblock & Rausch, 1967) n. comb.[PUBLICATION ABSTRACT]
