Neoglyphidodon
.
—
Since these species were placed in their own genus (as
Paraglyphidodon
; Allen, 1975a) and then relocated to the newly erected
Neoglyphidodon
(Allen, 1991)
, the composition of the group has been widely accepted and its monophyly has been corroborated consistently by subsequent phylogenetic studies (
Quenouille et al., 2004
; Cooper et al., 2009; Cowman and Bellwood, 2011;
Hofmann et al., 2012
;
Litsios et al., 2012a
,
2012b
;
Frédérich et al., 2013
;
Rabosky et al., 2013
,
2018
;
Lobato et al., 2014
; DiBattista et al., 2016;
Gaboriau et al., 2018
; Delrieu-Trottin et al., 2019). There are currently nine species classified in
Neoglyphidodon
, most of which inhabit the East Indies (Allen and Erdmann, 2012). We examined seven of the nine, missing only
N. crossi
and
N. mitratus
, and found robust support (100% bootstrap) for the monophyly of the genus. Our phylogeny shows a ladder-like topology of sequential sister taxa (
N. oxyodon
,
N. polyacanthus
,
N. bonang
,
N. melas
,
N. carlsoni
,
N. nigroris
, and
N. thoracotaeniatus
) that is congruent with all of the studies cited above except
Gaboriau et al. (2018)
and
Rabosky et al. (2018)
, where the positions of
N. carlsoni
and
N. nigroris
are switched. Of the two species not sampled, Allen (1991: 221) stated that
N. crossi
most closely resembled
N. bonang
and Allen and Erdmann (2012: 1137) stated that
N. mitratus
and
N. thoracotaeniatus
are a geminate species pair. If that is accurate, then the two most basal species,
N. oxyodon
and
N. polyacanthus
, would be the only ones that lack scales on the suborbital (Allen, 1991: 246) and the remaining seven species would share a scaled suborbital.
