Abstract

ENGLISH: The thread herrings, genus Opisthonema, family Clupeidae, are marine fishes that occur only in tropical and subtropical waters off both coasts of the American continent. The genus is composed of one Atlantic species and four Pacific species. Opisthonema oglinum (LeSueur), the single species in the western Atlantic Ocean, occurs from Brazil to Massachusetts, at Bermuda, and throughout the West Indies. Opisthonema libertate (Günther), Opisthonema bulleri (Regan), and Opisthonema medirastre, new species, are Pacific coastal species which occur together from Peru to Mexico (with at least one occasionally in California). Opisthonema berlangai, new species, is confined to the vicinity of the Galapagos Islands. SPANISH: Los arenques de hebra, género Opisthonema, familia Clupeidae, son peces marinos que se encuentran sólo en aguas tropicales y subtropicales cerca a ambas costas del continente americano. El género está compuesto de una especie en el Atlántico y de cuatro en el Pacifico. Opisthonema oglinum (LeSueur), única especie que medra el Océano Atlántico occidental, se encuentra del Brasil a Massachusetts, en Bermuda, y las Indias Occidentales. Opisthonema libertate (Günther), Opisthonema bulleri (Regan), y Opisthonema medirastre, especie nueva, son especies costaneras del Pacífico que aparecen entremezcladas del Perú a México (ocasionalmente por lo menos una de ellas en California). Opisthonema berlangai, especie nueva, está confinada a la vecindad de las Islas Galápagos.
