Thirty-one spinner dolphins Stenella longirostris stranded in La Paz Bay, B
aja California Sur, Mexico, were examined for endoparasitic helminths. The
following species were identified: Zalophotrema pacificum and Hadwenius tur
sionis (Digenea); Strobilocephalus triangularis, Trigonocotyle sp., and Tet
raphyllidea gen. sp. larva (Cestoda); immature Bolbosoma hamiltoni (Acantho
cephala); and Anisakis typica (Nematoda). Except for H. tursionis, all the
identified helminths are reported for the first time in Mexico. Stenella lo
ngirostris represents a new host for H. tursionis and A. typica.
