Drymonema larsoni Bayha & Dawson 2010

Drymonema larsoni Bayha & Dawson, 2010 Distribution See Fig. 4, Mendoza-Becerril et al. (2025) Notes The records included here are based on citizen-science observations. Two of the three valid species of Drymonema have been reported from the western Atlantic: D. gorgo Müller 1883 and D. larsoni (Collins et al. (2025). Drymonema gorgo was described from Brazil and has also been recorded in the Caribbean and the south-western Atlantic, including Bermuda and Argentina (Bayha and Dawson 2010, Gómez Daglio and Dawson 2017). Drymonema larsoni, on the other hand, was described from Dauphin Island, Alabama, with molecular confirmation from the type locality and from Florida (Bayha and Dawson 2010, Gómez Daglio and Dawson 2017). Paratypes from the British Virgin Islands and Puerto Rico support its presence in the Caribbean and additional records from Bermuda and South Carolina indicate a broad western Atlantic distribution (Bayha and Dawson 2010). As the records analysed here come from the Mexican Caribbean, where D. larsoni is the only species confirmed by morphological and molecular data, all observations are retained under that name in this checklist.
