On the taxonomic status of three eels (Teleostei: Anguilliformes) described from Leptocephali by Tommasi (1960)

The taxonomic status of three species of eels described from leptocephali larvae in 1960, is revised and elucidated: Leptocephalus anaelisae Tommasi, 1960, a member of Moringuidae, is confirmed as a junior synonym of Neoconger mucronatus Girard, 1858; Leptocephalus juliae Tommasi, 1960, a Muraenidae, is confirmed as a junior synonym of Uropterygius macularius (Lesueur, 1825); and Leptocephalus humbermariorum Tommasi, 1960, a Congridae, is now placed as species inquirenda in Rhynchoconger Jordan & Hubbs, 1925. Each of the three species was described based on a unique holotype, but none of the tree holotypes were found in any scientific collection investigated by us. Indeed, the three holotypes are considered to be permanently lost.

Brown-throated three-toed sloth (Bradypus variegatus Shinz, 1825) as a new host for Leiuris leptocephalus (Rud., 1819) Leuckard, 1850 / Preguiça comum (Bradypus variegatus Shinz, 1825) como novo hospedeiro de Leiuris leptocephalus (Rud., 1819) Leuckard, 1850

Vinte e três espécimes de Leiuris leptocephalus (Rud., 1819) Leuckard 1850 (Spirocercidae) foram recuperados do intestino delgado de uma fêmea de preguiça comum, Bradypus variegatus Shinz 1825 (Bradipodidae), em Ubatuba, estado de São Paulo. Os dados demonstram maior variabilidade morfométrica em relação aos dados da literatura, o que contribui para a caracterização morfológica desse nematódeo. Essa comunicação corresponde ao primeiro relato de B. variegatus como hospedeiro de L. leptocephalus.(AU)
