Anurans from the rainforest (Okomu National Park) and derived savanna (Agbede) locations in Nigeria were investigated for
their role either as intermediate or paratenic hosts of helminth infections. A total of 269 anuran specimens (157 from the
Okomu National Park and 112 from Agbede) were examined. Metacercariae of a strigeoid trematode, two nematode species, a
proteocephalid cestode, and an acanthocephalan were recovered frominfected hosts. Except for the strigeoid trematode, which was
only recorded in the rainforest, there was no ecological dichotomy in the distribution of the larval parasites recorded. Tree frogs
from the rainforest only served as second intermediate hosts for the strigeoid trematode. The two nematode larvae (type I and
type II) found in the body cavity of the infected host are believed to use them as paratenic hosts. Tree frogs were the predominant
intermediate hosts of the proteocephalid cestode larvae in the rainforest, while Ptychadena and Phrynobatrachus spp. served this
function in the derived savanna. The occurrence of cystacanths in the anurans from both biotopes confirms their known role as
paratenic host for acanthocephalans. Afrixalus dorsalis is a new host record for the ascaridoid nematode while the finding of the
strigeoid trematode, the proteocephalid cestode larvae and acanthocephalan cystacanths in the anurans investigated represents
new geographical records.
