Verticil with 8-12 yellow to dark brown spines unequal in size (Fig. 13D-H). Dorsal hook broad, curved, larger than all other spines, covering central disc. Other spines with pointed tip and pronounced knob each. First and second pair of dorsal spines (lateral to dorsal hook) with tips and trunks wider than all other spines (Fig. 13D-H). Collar chaetae bayonet with two blunt teeth; distal blade smooth.
Taxon discussion Hydroides brachyacanthaRioja, 1941 ( Rioja 1941a), an important fouling serpulid species originally described from Mazatlan(Southern Gulf of California, Mexico) and Acapulco (southern Mexican Pacific), has been reported from the Mexican Pacific and numerous tropical and subtropical localities ( Rioja 1941a, Tovar-Hernandezet al. 2009, Bastida-Zavala and ten Hove 2003, Bastida-Zavala 2008, Bastida-Zavala et al. 2016). At the MazatlanPort, the mean annual density of H. brachyacanthaduring 2009 was 80 ind m-2 (fouling assemblages in metallic buoys), with a minimum of 4 ind m-2 in November and a maximum of 304 ind m-2 in March ( Sun et al. 2016). Recently, a neotype was established by Sun et al. (2016), who also demonstrated that the previous records from the species in Australia belongs to a different lineage.
