Abstract
Two new species of the earthworm family Rhinodrilidae (Clitellata), from Maranhão state, Brazil, were studied by dissection. Andiorrhinus (Turedrilus) miricuri n. sp. is the first record of a big earthworm for this region with three pairs of large spermathecae in segments 7–9 and one pair of tubercula pubertatis bands lateral to b line in XX–XXV. Andiorrhinus (Turedrilus) barrosoi n. sp. lacks spermathecae and has one pair of tubercula pubertatis bands lateral to b line in XX–(1/3) XXIV. The earthworms described are from the most threatened region of Amazonia where 75% of forest cover is already lost. More information is urgently necessary to assess their ecology and vulnerability status.
