Dactylamblyops corberai n. sp., a new mysid (Crustacea: Mysida) from the deep Mediterranean Sea
A new Erythropinae mysid, Dactylamblyops corberai n. sp., is described from specimens sampled with a 500-mm plankton net attached to a bottom trawl in the Ionian Sea (eastern Mediterranean). This new species is the first Dactylamblyops species described from the Mediterranean Sea. Based on a revisio...

| Summary: | A new Erythropinae mysid, Dactylamblyops corberai n. sp., is described from specimens sampled with a 500-mm plankton net attached to a bottom trawl in the Ionian Sea (eastern Mediterranean). This new species is the first Dactylamblyops species described from the Mediterranean Sea. Based on a revision of additional material from several cruises made in recent years, we conclude that D. corberai is a widespread species in the deep Mediterranean near-bottom suprabenthic community at depths between 398 and 1859 m. The main distinguishing features of D. corberai are the shape of the eyes and their ocular process, and the shape of the labrum with two rows of clusters of short setules and two areas covered with small, scale-like protrusions not described in any other species of the genus. D. corberai belongs to the morphological hodgsoni group of Dactylamblyops species. Se describe un nuevo misidáceo de la subfamilia Erythropinae, Dactylamblyops corberai n. sp., en base a diversos ejemplares muestreados en el mar Jónico (Mediterráneo Oriental) con una red de plancton de 500 mm adosada a una red de arrastre comercial. Esta nueva especie es la primera del género Dactylamblyops descrita en el mar Mediterráneo. El estudio de diverso material adicional recolectado en diferentes campañas de muestreo permite concluir que D. corberai presenta una amplia distribución en el nivel suprabentónico de las zonas profundas del Mediterráneo, entre profundidades de 398 a 1859 m. Las principales características morfológicas de D. corberai son la forma de los ojos y de la protuberancia ocular, así como la forma peculiar del labrum con dos filas de pequeñas sétulas y dos áreas cubiertas con salientes en forma de escamas. D. corberai pertenece al grupo morfológico de especies tipo hodgsoni del género Dactylamblyops. |
