Amblypomacentrus .

— As noted above, this genus is revised herein to include three species formerly classified as Chrysiptera ( A. annulatus, A. kuiteri, and A. tricinctus) because these black-and-white striped species are more closely related to species of Amblypomacentrus sensu stricto in our phylogeny (Fig. 1). This result corroborates Cooper et al. (2009), who found ‘‘ Chrysiptera ’’ kuiteri more closely related to A. clarus . They noted that all three species of ‘‘ Chrysiptera ’’ shared similarities in size, coloration, and habitat preference with members of Amblypomacentrus . Phylogenetic studies since Cooper et al. (2009) have recovered similar relationships between those three ‘‘ Chrysiptera ’’ and Amblypomacentrus (e.g., Cowman and Bellwood, 2011; Litsios et al., 2012a; 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). Allen (1975a: 42) mentioned that Amblypomacentrus closely resembles some species of Chrysiptera (as Glyphidodontops), but he did not specify which ones. Randall et al. (1997: 252) commented that the coloration of A. breviceps is similar to Chrysiptera tricincta [¼ A. tricinctus]. Based on the distribution of barred color patterns in Pomacentridae, Merilaita and Kelley (2018: fig. 4) showed that distinct vertical bars are clustered in groups of closely related damselfish species (e.g., Abudefduf, Amphiprion). Other traits shared by the species of Amblypomacentrus sensu novum include uniserial teeth (Allen, 1975a; Allen and Rajasuriya, 1995; Allen and Adrim, 2000; biserial in C. annulata; Allen and Randall, 1974, 1981) and preference for sand or silt habitats (Allen, 1975a, 1991; Allen and Rajasuriya, 1995; Randall et al., 1997; Allen and Adrim, 2000; Allen et al., 2003; Randall, 2005; Cooper et al., 2009; Lepoint et al., 2016).
