Two new species of spionids from the genera Dispio and Prionospio (Polychaeta: Spionidae) from the Iberian Peninsula with redescription and notes on Prionospio (Minuspio) multibranchiata Berkeley, 1927.

A re-assessment of spionid specimens collected from coasts around the Iberian Peninsula and initially assigned to Dispio uncinata Hartman, 1951 and Prionospio multibranchiata Berkeley, 1927 resulted in the recognition of two new species from the genera Dispio and Prionospio: Dispio glandulosa sp. nov. and Prionospio (Minuspio) sanmartini sp. nov. In addition, the examination of specimens collected near the type locality of P. multibranchiata led to a re-description of this species. The specimens examined do not correspond to the material collected from the Iberian Peninsula and it is unlikely that P. multibranchiata is found in northern European waters.
