title: Parasitic infections of the African dwarf crocodile (Osteolaemus tetraspis) and the ornate Nile monitor (Varanus ornatus) from Nigeria.
abstract: The parasitic infections of market derived Osteolaemus tetraspis from the rainforest and Varanus ornatus from locations in the savanna-mosaic and the rainforest of southern Nigeria were investigated. Parasites recovered from O. tetraspis included members of the Pentastomida, Trematoda and Nematoda. An undescribed pentastomid belonging to the family Sebekidae was recovered from O. tetraspis. The same parasite was also found to parasitize V. ornatus from the rainforest. Other parasites found in O. tetraspis were Pseudoneodiplostomum thomasi, Dujardinascaris sp. and larva of a Camallanus sp. Varanus ornatus from the rainforest and the derived savanna had some parasites including Duthiersia fimbriata, an unidentified pseudophyllidean cestode and Tanqua tiara in common. Cosmocerca ornata and Oswaldocruzia hoepplii were restricted to hosts from the derived savanna while the unidentified trematode occurred only in lizards from the rainforest. The unidentified pseudophyllidean cestode bears a close resemblance to Probothriocephalus, a cestode previously reported only from deep water teleosts. Pseudoneodiplostomum thomasi and Duthiersia fimbriata are new locality records for Nigeria.
