Similar Species

The following combination of characters distinguishes Plectranthias grahami from all congeners: dorsal rays X,15; pectoral rays 18; lateral-line scales 41–42; and gill rakers 6+13.


The species is named for Ken Graham, who collected the holotype, and has contributed extensively to our knowledge of New South Wales trawl fishes and invertebrates. He noted (pers. comm.) that this is the only specimen of the species he has ever collected, despite several decades of extensive exploratory trawling in similar depths off the New South Wales coast.
