Introduction
Following Anderson & Adlard (1994) and Huber (2010) Saccostrea glomerata (Gould, 1850) and S. comercialis (Iredale & Roughley, 1933) are treated here as conspecific (Middelfart & Ponder pers. comm.). This is unlike Torigoe (2004) who treated them as separate taxa based on trivial allozyme data (see Buroker et al. 1979a, 1979b). Torigoe also listed S. glomerata under the perceived prior Fiji/Samoan name Saccostrea circumsuta (Gould, 1850). Saccostrea circumsuta (Gould, 1850) is known from Fiji and Samoa and although these two species may be related, S. circumsuta is a tropical species, whereas S. glomerata appears to be confined to more temperate regions and not conspecific (see Beu 2006: 211 for more comments).
The name Saccostraea cucullata (Born, 1778) has also been used in association with Saccostrea glomerata (Gould, 1850). Lam & Morton (2006) found S. glomerata to nest inside the cucullata superspecies clade (which is highly likely to constitute a number of taxa). However, according to Torigoe (2004) S. cucullata is confined to the Atlantic Ocean, and Huber (2010) reported it from the Atlantic Ocean and western Indian Ocean. Furthermore, Sekino & Yamashita (2016) found greater than 10% nucleotide difference for all cucullata lineages that they studied, comparable with the level of intraspecific divergence in Crassostrea. Here we follow Sekino & Yamashita (2016), authors cited therein, and WoRMS (2021), in treating S. glomerata as a valid species separate to S. cucullata
The relationships of the "S. cucullata"-like oysters of the Indo-Pacific (see Sekino & Yamashita, 2016) remains uncertain and will not be resolved until major molecular studies have been undertaken, extending Lam & Morton (2006) study. Similar oysters also occur in tropical parts of Australia and the taxonomy of these taxa requires further study.
