Amblyglyphidodon .

— The 11 Indo-Pacific species classified in Amblyglyphidodon are all deep-bodied and orbiculate (body depth 1.5–1.8 in SL; Allen, 1975a, 1991, 1995; Allen and Randall, 2002; Allen et al., 2012a, 2012b). Since Allen’s (1975a) revision of the family recognized Amblyglyphidodon as a separate genus, these species have been widely accepted as forming a natural group. Monophyly of Amblyglyphidodon receives strong support (100% bootstrap; Fig. 1 ) which corresponds to all phylogenetic studies with sufficient taxon sampling ( Quenouille et al., 2004; Cooper et al., 2009; Cowman and Bellwood, 2011; Litsios et al., 2012a, 2012b; Frédérich et al., 2013; Rabosky et al., 2013, 2018; Lobato et al., 2014; DiBattista et al., 2016; Mirande, 2016; Gaboriau et al., 2018; Delrieu-Trottin et al., 2019). Of the currently recognized species, this analysis lacks only A. flavopurpureus . Allen et al. (2012b: 1128) found A. batunaorum and A. ternatensis to be closely related. The two species were previously regarded as color variants (Allen, 1995). However, they are not sister species in this phylogeny. Instead we found them to be sequential sister taxa to the rest of Amblyglyphidodon . Amblyglyphidodon batunai was emended to A. batunaorum by Fricke et al. (2020), because the name was explicitly stated to be in honor of multiple people, one man and one woman (Allen, 1995; ICZN, 1999: Arts. 31.1.2, 32.5.1). Allen and Randall (2002) identified a ‘‘ leucogaster complex’’ composed of A. indicus , A. leucogaster , A. melanopterus , and A. orbicularis . Our phylogeny found those species, minus A. leucogaster , together in a clade, along with A. curacao and A. silolona ( Fig. 1 ). Although its monophyly is well supported, ‘‘the phylogeny of Amblyglyphidodon is complex and warrants further attention’’ (Allen et al., 2012a: 1134).
