Abstract
Myopiarolis tona sp. nov. is described from the Challenger Plateau, southern Lord Howe Rise and the west coast of the North Island, New Zealand at depths of 634-1250 m. M. tona sp. nov. can be identified by the prominent posteriorly directed dorsal nodule on fused pereonites 5-7. There are nine species in four genera of the cold-water, epibenthic family Serolidae recorded from New Zealand waters, three species of Myopiarolis Bruce, 2009, one undescribed species of Acutiserolis Brandt, 1988, four of Brucerolis Poore and Storey, 2009 and the monotypic Spinoserolis Brandt, 1988.
Highlights
The Serolidae are a relatively small and primarily Southern Hemisphere family of 23 genera and 123 species (Schotte et al 2015), nine of which occur in New Zealand
The taxonomy of the New Zealand Serolidae has most recently been updated by Bruce (2008), Poore and Storey (2009) and Storey and Poore (2009)
At present the New Zealand Serolidae are represented by nine species in four genera, namely Myopiarolis Bruce, 2009, one of Acutiserolis Brandt, 1988, four of Brucerolis Poore and Storey, 2009 and the monotypic Spinoserolis Brandt, 1988
Summary
The Serolidae are a relatively small and primarily Southern Hemisphere family of 23 genera and 123 species (Schotte et al 2015), nine of which occur in New Zealand. Bruce (2009) reviewed the genus Myopiarolis for the southwestern Pacific and gave a key to the serolid genera of the tropical and subtropical Indo-Pacific, which can be used to identify the New Zealand genera.
