Remarks. Hydroids identified under either the binomen Dynamena disticha ( Bosc, 1802) or one of its various synonyms are widespread and of frequent occurrence in the tropical and warm-temperate western North Atlantic. The reported range of the species extends from southern New England ( Nutting 1904) and Bermuda (Calder 1990 [1991a]) to the Caribbean coast of northern South America ( Wedler 1975), and on to Argentina in the southwest Atlantic ( Oliveira et al. 2016). Well-known as part of the Sargassum fauna, it is found in the Sargasso Sea and the Gulf of Mexico, and is carried far northwards in the warm Gulf Stream on gulfweed to waters east of Atlantic Canada ( Fraser 1918). As apparent from distribution records below, it has been collected several times previously on the Gulf coast of Florida. Dynamena disticha has been reported over a bathymetric range of 0–256 m ( Fernandez & Marques 2018), but the species is much more frequent in near-surface waters.

Molecular analyses ( Moura et al. 2011; Maronna et al. 2016) reveal that Dynamena Lamouroux, 1812 as presently constituted is polyphyletic and in need of significant revision. Indeed, Dynamena disticha is shown in such studies to be genetically distant from the type species of the genus, D. pumila ( Linnaeus, 1758) . Sertularia quadridentata Ellis & Solander, 1786 , another species likewise remote from D. pumila but formerly included in Dynamena , was referred earlier ( Calder 2013) to Pasya Stechow, 1922 , as P. quadridentata . Dynamena disticha needs to be reassigned, along with any closely related species, to another genus. Such re-classification needs careful consideration and is beyond the scope of this study.

Moura et al. (2011) detected potential cryptic species within populations identified as D. disticha from western Europe. Questions also exist about possible taxonomic differences between two forms assigned to the species in the western Atlantic ( Calder 2013). One of these, a stunted form usually 1 cm high or less, is common on pelagic Sargassum as originally described by Bosc (1802). The other morphotype, more robust and reaching 5 cm high, has been reported largely from inshore waters on various benthic substrates.

Hydroids of D. disticha are typically bright yellow in colour ( Bosc 1802; Calder 1971, 1983). While seldom branched, a single hydrocladium may occur on large colonies ( Calder 1971). In this character it differs from the closely related but alternately branched D. moluccana ( Pictet, 1893) . Dynamena dimorpha Galea, in Galea & Ferry 2015 , a species much resembling D. disticha , has recently been described from Martinique in the Caribbean Sea. It differs in having both unbranched and pinnately branched colonies, thicker and less collapsable perisarc, and hydrothecae that are shallower and wider ( Galea & Ferry 2015). From the original account of that species, symbiotic zooxanthellae may be present.

Gonothecae in D. disticha , resembling inverted Chinese lanterns, usually occur on the hydrorhiza. They may also arise from internodes of the hydrocaulus or even from old hydrothecae ( Calder 1971; Galea 2008). In the latter case, their morphology is atypical in being sac-shaped with a rounded distal end, they vary in length and width, and their walls are smooth or only slightly undulated ( Galea 2008).

While believed to be a substrate generalist ( Calder 1971, 1991c; Oliveira 2016), this hydroid often occurs on seagrasses and especially on pelagic Sargassum . If estuarine populations have been correctly assigned to this species, D. disticha is both euryhaline and eurythermal. It extends from coastal waters up-estuary to about the 18‰ isohaline ( Calder 1976), and it tolerates temperatures as low as about 9° C before becoming dormant (Calder 1990). Hydroids, including D. cornicina (= D. disticha ), were found to be the primary food of Atlantic spadefish ( Chaetodipterus faber ) in estuarine areas and offshore reefs of South Carolina ( Hayse 1990).

The nomenclature of D. disticha has been reviewed elsewhere (Calder 1990 [1991a]). A detailed synonymy of the species exists in Medel & Vervoort (1998).
