Solitary fan worm with soft tubes, composed of fine sand and covered by algae and bryozoans. Body length 14-26 mm, 1.5-2.3 mm width. Radiolar crown length 6-10 mm with 12-14 pairs of radioles. Thorax with eight chaetigers and abdomen with 63-67 chaetigers. Radioles with brownish maculae (no eyes or ocelli) along radiolar length (Fig. 12 View Figure 12 D-F). Radiolar tips with broad flanges. Ventral shields well developed, contacting tori. Ventral collar margin incised, forming two rounded lappets with triangular tips.

Taxon discussion

Members of Parasabella   seem like Acromegalomma   at first view, but the latter have subdistal compound eyes in radioles (absent in Parasabella   ). Common in fouling from the Gulf of California ( Tovar-Hernández et al. 2009; Tovar-Hernández et al. 2019; Bastida-Zavala et al. 2016).
