Type material. HOLOTYPE: MNCN 16.01 About MNCN /18416: Gulf of Venezuela (11°01’69”N, 71°26’15”W) . PARATYPES (from same sample): MNCN 16.01 About MNCN /18417 (11 complete specimens) ; MNCN 16.01 About MNCN /18418 (28 incomplete specimens) ; MNCN 16.01 About MNCN /18419 (two fragments exhibiting regeneration) ; MNCN 16.01 About MNCN /18420 (two specimens on SEM stub) , MNCN 16.01 About MNCN /18421 (one specimen on SEM stub) .
Diagnosis. 20 body chaetigers (three thoracic + 17 abdominal). Branchial crown provided with three pairs of tentacles, each with three major ramifications, first very close to crown base, second located at mid-length and third very close to distal end. Total length of crown about 1/2 of thorax length. A pair of minute eyespots located at the base of crown. Junction between thorax and tentacle crown marked by a distinct, straight collar. Relative length of thoracic chaetigers: 1-2-1. Thorax with three pairs of notopodia provided with capillary chaetae, neuropodia absent. First abdominal segment about same length or slightly longer than total thoracic length. Second and third abdominal chaetigers the longest, similar in length. From fifth chaetiger onwards, segments decreasing in length and width. Abdominal notopodia well developed and provided with capillary chaetae; neuropodia consisting of wide, sessile tori with several rows of neurochaetal hooks similar throughout, with shaft ending in two teeth located side by side. Pygidium simple.
Etymology. Named vieitezi , after Dr. José Manuel Viéitez, Universidad de Alcalá de Henares (Madrid, Spain).
