Taxon discussion
Hydroides brachyacantha
Rioja, 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-Hernandez
et al. 2009
,
Bastida-Zavala and ten Hove 2003
,
Bastida-Zavala 2008
,
Bastida-Zavala et al. 2016
). At the
Mazatlan
Port, the mean annual density of
H. brachyacantha
during 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.
