Thysanotaenia congolensis n. sp. (Cestoda: Anoplocephalidae) in the lesser savanna cane rat, Thryonomys gregorianus from Democratic Republic of Congo, Africa.
Ten (100%) lesser savanna cane rats, Thryonomys gregorianus, collected from the Lake Kivv area of the Democratic Republic of Congo, Africa were found to be infected with an undescribed anoplocephalid tapeworm, Thysanotaenia congolensis n. sp. Like other species of Thysanotaenia, T. congolensis n. sp. has the ovary and vitellarium centrally located, and the egg capsules and testes are intervascular. The new species differs from the 2 existing species, Thysanotaenia lemuris in lemurs and Thysanotaenia cubensis in humans, in being smaller (34-50 mm long) and in having a smaller scolex (260-410 microns in diameter), a shorter cirrus sac (115 microns long), and smaller eggs (40 microns in diameter). Anastomoses of the excretory system and formation of egg capsules in the new species are also described.
