ABSTRACT
Sinocyclocheilus cyphotergous was described by Dai in 1988 as Gibbibarbus cyphotergous based on a single specimen collected in Luodian County, Guizhou Province, China. The holotype (the only one type specimen) has been lost and the original description was vague and was published in a report with limited circulation. A specimen collected from the type locality in 2015 was the basis for a detailed redescription of the species and designation of a neotype. Sinocyclocheilus cyphotergous can be distinguished from all other congeners by the following combination of characters: a humpback profile with a fleshy dorsal projection; a hard last unbranched ray of dorsal fin with a serrated rear edge; and nearly straight lateral line. This species is the only member of the genus with a fleshy dorsal projection composed of adipose tissue (either a bony projection located on the nape or fleshy humpback is present in all other species). The conservation status of S. cyphotergous is uncertain and most likely critical due to its limited distribution, apparent rarity (based on low frequency of detection), and the potential for increased impacts to its habitat due to diminished quantity and quality of groundwater.

    Abstract  The type specimens of platycephalid Platycephalus endrachtensis Quoy and Gaimard 1825 are regarded as being conspecific with Platycephalus arenarius Ramsay and Ogilby 1886, so the latter becomes a junior synonym. This species is characterized as having a caudal fin with four or...

    This study deals with the nervus vagus of Mugil cephalus. The microscopic observations showed that, the nervus vagus arises from the brain by one root which leaves the cranial cavity through the jugular foramen. The intracranial dorsal vagal ramus arises from the vagal root and enters its own...

    Evidence is given of the second documented record of Gephyroberyx darwinii (Beryciformes: Trachychthyidae) in the Mediterranean. One specimen was caught offshore S. Agata di Militello (Tyrrhenian Sea) in August 2011 by trammel net. Herein are reported its morphometric and meristic features.

    We studied the startle response of the African butterfly fish, Pantodon buchholzi (Osteoglossomorpha, Osteoglossoidea). It is an upward movement, mediated by abduction of the pectoral fins, and is elicited by mechanical and visual stimuli. Because this fish inhabits the first few centimeters...
