Grammoplites vittatus (Valenciennes), often previously overlooked by authors or regarded as a junior synonym of G. scaber (Linnaeus), is shown here to be a valid species.  It has more gill rakers (7-8) then G. scaber and G. knappi (usually 6) and a narrower interorbital width than G. scaber.  A key to the species of Grammoplites Fowler is  given. 

The gempylid Nesiarchus nasutus is reported for the first time from Argentinean waters, the southernmost occurrence of the species in the Southwestern Atlantic. This suggests that the fluctuating environmental characteristics of the area would be proper for the presence of tropical and subtropical species.

THE DESCRIPTION of new taxa in a "Handbook of Hawaiian Fishes" recently submitted for publi cation was considered inadvisable . Certain of these are grouped together here, i. e., three new species of Gobiidae (Quisquilias aureoviridis, Q. limbatosquamis, and Hazeus ttnisquamis), a new genus and species of Callionymidae (Pogonymtts pogognathus), and a new suborder of Perciformes (Schindlerioidei...

A comparison of the composition and structure of parasite communities of the Brazilian flathead, Percophis brasiliensis Quoy et Gaimard (Perciformes: Percophidae) among seasons during one year was carried out in the Argentine Sea. A total of 195 fish specimens were examined and 25 parasite species were found. Parasite communities in seasonal samples showed a high degree of homogeneity in taxono...

The slender ponyfish Equulites elongatus was recorded for the first time in the Mediterranean near Tel-Aviv, Israel on 27 May 2011. This Indo-Pacific species evidently reached the Mediterranean by crossing the Suez Canal.

The marbled goby Pomatoschistus marmoratus, a species inhabiting coastal Mediterranean lagoons, has been studied by measuring its mitochondrial DNA variation. This analysis revealed a Mediterranean west vs east split and, subsequently, an eastern differentiation among the Libyan-Tunisian Gulf, the Adriatic Sea and the Aegean Sea. The high cohesion between the samples collected in the vast area ...

A parasitological survey was carried out on a sample of sixty mutton snappers (Lutjanus analis) that were caught on the coast of Alagoas, northeastern Brazil. The parasite diversity and infection levels were low. The ectoparasite Rocinela signata Schioedte & Meinert, 1879 (Isopoda: Aegidae), and larvae of two endoparasites, Trypanorhyncha gen. sp. and Hysterothylacium sp. (Nematoda: Anisakidae)...

We describe 5 specimens of Choerodon margaritiferus Fowler and Bean, 1928 (94.5-107.0 mm standard length, 1 male and 4 females) collected near Okinawa Island, southern Japan. This is the northernmost record of this species and the first record of it in Japanese waters; until now, C. margaritiferus was recorded only from the western central Pacific. This species was originally described on the b...

Based on light and scanning electron microscopical studies, the following five species of the Philometridae (Nematoda: Dracunculoidea) are described from female specimens collected from marine fishes off the southwestern coast of Java, Indonesia: Philometra lobotidis sp. n. from the abdominal cavity of the Atlantic tripletail Lobotes surinamensis (Bloch) (Lobotidae, Perciformes); Philometra jav...

Dolphinfishes (Coryphaenidae) are pelagic predators distributed throughout all tropical and subtropical oceans and are very important for commercial, traditional, and sport fishing. This small family contains the Coryphaena hippurus and Coryphaena equiselis species whose chromosomal aspects remain unknown, despite recent advances in cytogenetic data assimilation for Perciformes. In this study, ...
