Abstract

The oegopsid squid family Onychoteuthidae was recently revised based on morphology, but sufficient material for a complementary molecular analysis has not been available until now. In the present study, over 250 sequences of cytochrome c oxidase subunit I (COI) and 16S rRNA for 222 individuals were analysed to create a combined phylogeny for the family. Results support monophyly for the family and all seven onychoteuthid genera (including Moroteuthopsis , established herein as the senior genus name for species formerly attributed to Kondakovia ); 29 genetically distinct species were recovered, with the BIN (Barcode Index Number) analysis for COI showing good congruence overall with morphological species groupings. No sequences were available for five additional known species, making the total family diversity likely to exceed 34 species. Seven of the BINs formed in this study appear to represent undescribed taxa, suggesting that even in this relatively well-studied family, much additional work remains before a comprehensive understanding of the diversity and evolutionary relationships for the Onychoteuthidae can be achieved.

Abstract

Hooked squids (Family Onychoteuthidae Gray, 1847) inhabit all oceans of the world except the Arctic. This family is currently comprised of 25 species belonging to seven genera. In the southeastern Pacific Ocean, approximately five onychoteuthid species have been previously identified, but true identity of these taxa is uncertain. We reviewed museum collections, from Chile, United States and New Zealand, and literature to elucidate the presence of hooked squids in the southeastern Pacific Ocean. The present status of the Onychoteuthidae from the southeastern Pacific only includes four species: Onychoteuthis aequimanus, Onykia ingens, Onykia robsoni, and Kondakovia nigmatullini.

The present status of the Onychoteuthidae from the southeastern Pacific only includes four species: Onychoteuthis aequimanus, Onykia ingens, Onykia robsoni, and Kondakovia nigmatullini. Los calamares ganchudos (Familia Onychoteuthidae Gray, 1847) habitan en todos los océanos excepto en el Ártico. Esta familia está compuesta actualmente de 25 especies pertenecientes a siete géneros. En el Océano Pacífico suroriental, aproximadamente cinco especies de Onychoteuthidae han sido identificadas previamente, pero su estatus taxonómico es incierto. Se revisaron las colecciones de museos de Chile, Estados Unidos y Nueva Zelanda, y la literatura para dilucidar la presencia de calamares con ganchos en el Pacífico suroriental. El estado actual de la familia Onychoteuthidae en esta área incluye solo cuatro especies: Onychoteuthis aequimanus, Onykia ingens, Onykia robsoni y Kondakovia nigmatullini.
