Publication details
Dictyota humifusa Hörnig, Schnetter & Coppejans in Hörnig et al. 1992: 57, fig. 6

Published in: Hörnig, I., Schnetter, R., Prud'homme van Reine, W.F., Coppejans, E., Achenbach-Wege, K. & Over, J.M. (1992). The genus Dictyota (Phaeophyceae) in the North Atlantic. I. A new generic concept and new species. Nova Hedwigia 54: 45-62, 6 figs, 3 tables.

Taxonomic notes
According to Silva, Basson & Moe (1996: 594) the taxon Dictyota ceylanica Kützing var. rotundata Weber-van Bosse is a possible taxonomic synonym of this species. Also according to Silva, Basson & Moe (1996: 594), the name Dictyota adnata has been misapplied to this species by various authors; please consult original reference for full details. Bula-Meyer (1994) and Wynne (1998) consider Dictyota humifusa conspecific with D. pfaffii (q.v.), but Littler & Littler (1997: 73) provide characters for their separation. Wysor & De Clerck (2003) do not agree with Bula-Meyer's (1994: 177-181) conclusion concerning D. humifusa.

Distributional notes
South & Skelton (2003) note that Fijian records of Dictyota require a thorough revision comparable with that made for Indian Ocean species by de Clerck (1999).

General environment
This is a marine species.

Type information
Type locality: Punta Chengue, Santa Marta, Departamento del Magdalena, Colombia (Silva, Basson & Moe 1996: 594). Holotype: COL A-4287 (De Clerck 2003: 171).
