Taxonomic note
John &t al. (2004) cite Dasya arbuscula (Dillwyn) C. Agardh as a synonym of this species. Furnari et al. (2003) note that "although D. arbuscula (Brown ex Dillwyn) C. Agardh is a taxonomic synonym of Aglaothamnion sepositum (Gunnerus) Maggs & Hommersand, we follow Gómez Garreta et al. (2001) in considering Italian records of D. arbuscula as sensu Harvey. Therefore, they are here referred to D. hutchinsiae." Includes Dasya arbuscula sensu Harvey (1849, pl. CCIV). "This species, in the Mediterranean Sea was erroneously recorded as Dasya arbuscula (Dillwyn) C. Agardh [= Aglaothamnion sepositum (Gunnerus) Maggs et Hommersand taxon excludendum]. Agreeing with Gómez Garreta et al. (2001: 444, note no. 75), the above records are here referred to as D. arbuscula sensu Harvey and consequently to D. hutchinsiae. It should be noted that Dasya arbuscula var. villosa was erroneously considered by Furnari et al. (1999: 29 and 2003: 91) as a synonym of D. hutchinsiae instead of D. corymbifera (see the note to a D. corymbifera)." (Cormaci & al. 2023: 526). - (11 May 2006) - G.M. Guiry
