[Three Nadejdolepis Spasskii & Spasskaya, 1954 (Cestoda: Hymenolepididae) parasites of Charadrii (Aves) of Belize].

Three Nadejdolepis from Belize, Central America, represent new geographical records (1) Nadejdolepis paranitidulans (Golikova, 1959) (rostellar hooks 40-44 microm long) from Charadrius alexandrinus; (2) N. arenariae (Cabot, 1969) n. comb. (rostellar hooks 89 microm long) from Arenaria interpres; and (3) N. litoralis (Webster, 1947) (rostellar hooks 81-85 microm 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 microm 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) comb. and M. alaskensis (Deblock & Rausch, 1967) n. comb.
