Ituglanis amphipotamus, new species, is distinguished from all congeners by the combination of the following characters: anterior cranial fontanel present, i,5 pectoral-fin rays, nasal canal and antorbital segment of infraorbital canal absent, five or six pairs of ribs, 39 post-Weberian vertebrae. It can be further distinguished from the sympatric I. proops by the size of the interopercular patch of odontodes. The new species is described from the Rio Ribeira de Iguape and the upper Rio Tietê basins in the southeastern region of Brazil. Comments on the biogeography of the new taxa and putative relationships with its congeners are presented. [Zoobank: urn:lsid:zoobank.org:act:AC2F3365-92C0-4444-AC89-9546365158EC].
双栖伊氏鲶，新物种，与所有同属物种的区别在于具有以下特征组合：有前颅囟，15根胸鳍鳍条，无鼻管和眶下管的眶前段，五或六对肋骨，39枚韦伯氏器后的椎骨。它还可通过 interoperculum 上齿状突斑块的大小与同域分布的普氏伊氏鲶相区分。该新物种采自巴西东南部的伊瓜普河和蒂埃特河上游流域。文中对新分类单元的生物地理学以及与同属物种可能的关系进行了讨论。[动物学数据库：urn:lsid:zoobank.org:act:AC2F3365 - 92C0 - 4444 - AC89 - 9546365158EC]
