Body 13-34 mm long, 2-4 mm wide, radiolar crown 6-17 mm long with 13-29 pairs of radioles, thorax with 13 chaetigers and abdomen with 46-82 chaetigers. Gregarious species (Fig. 10 View Figure 10 A). Soft tubes constructed by fine sand. Each radiole with three purple bands without a uniform distribution pattern (Fig. 10 View Figure 10 B). Within each purple radiolar band, there is a pair of compound eyes (three pairs of eyes per radiole). Ventral margins of thick base spiralling inwards to form three whorls (Fig. 10 View Figure 10 C). Collar with purple spots dorsally and ventrally. Thorax with purple spots anterior to each thoracic notochaetae (Fig. 10 View Figure 10 D). Purple maculae between ventral shields and tori (Fig. 10 View Figure 10 E). In lateral view, dorsal and ventral spots are seen in each segment, located at the ends of notochaetae and neurochaetae (Fig. 10 View Figure 10 F).

Taxon discussion

This is the only fan worm that has been included in the invertebrate guides from the Gulf of California ( Kerstitch and Bertsch 2007). It has been reported in the Gulf of California ( Kudenov 1975a) and Pacific Panama and Costa Rica ( Knight-Jones and Perkins 1998).
