A New Species

A new species of Loricaria is herein described from the Turiaçu River basin, Eastern Amazon region, Maranhão state, Brazil, within the Maranhão Hydrological Unit (MHU). Loricaria turi differs from its congeners mainly by the following combination of characters: abdominal plate development confined to the posterior median region, pectoral girdle mostly naked, with cluster of plates near pectoral fin bases; large eyes (minimum orbital diameter 16.2–20.7% of HL and maximum orbital diameter 19.8–24.0% of HL), 214.4 mm of maximum standard length, and large basicaudal plate (16.6–29.2% of HL). The description of this new species strengthens the hypothesis that the Maranhão Hydrological Unit (MHU) is a possible area of endemism for freshwater fishes and contributes to the knowledge of the freshwater fish diversity and composition of the region.

A New Species

ABSTRACTA new species in the genus Goezia is described from aquatic reptiles of the northern shores of Australia, west of Cape York Peninsula. It was collected from Crocodylus porosus, from a file snake (Achrochordus granulatus), and from sea snakes (Lapemis hardwickii, Enhydrina schistosa, Hydrophis elegans, and H. caerulescens). The new species is compared with G. fluviatilis from Australian freshwater fish, with G. minuta from marine fish of the east coast of North America, and with G. spinulosa and G. intermedia from South American freshwater fish. The host-relationships of the genus are discussed.
