Type locality. Near Avalon , Santa Catalina Island, California, USA .

Vouchers. HEC 14812 (zF), 26 September 2001, Chaland (s.s. 8) ; HEC 14876 (zF), 1 October 2001, Totor (s.s. 9) .

Ecology. Epiphytic on Pterocladiella caerulescens and Cryptonemia crenulata between 8 and 12 m depth.

Indian Ocean distribution. India, Tanzania, Rodrigues (this paper).

Note. Cormaci and Furnari (1988) considered A. breviramosa a synonym of A. elegans (Berthold) Price and John. This taxonomic decision, however, is not entirely followed by subsequent authors and needs further study. Following Kim and Lee (1990), Millar (1990) and Abbott (1999), we prefer to keep both entities as separate species. It should be noted that A. elegans is reported from Mauritius by Børgesen (1952: 39–40).
