Remarks.
Trigla brandesii
Bleeker 1850
has no extant
type
material (M.J.P. van Oijen, pers. comm.) and a non-specific description, but may be referable here. Young stage specimens referable to this subgenus include
Pterygotrigla fercula
(Whitley 1938)
, a juvenile, and two larvae are
incertae sedis
.
