Comments

Taxonomy from Fossilworks.org.

Bannikov 2008 notes on p. 66 that "examination of the lectotype of Apogon spinosus resulted in the conclusion that the species name spinosus is a synonym of Acropoma lepidotum (syn. nov.)." 

For grammatical reasons, the species name is Acropoma lepidotum and not Acropoma lepidotus, as in Sorbini 1975.

Corrected diagnosis for Acropoma lepidotum from Sorbini 1975, p. 178 (translated from Italian by oilshale): "Body moderately elongate, two separate dorsal fins, ventral margin arcuate. Teeth with slightly pointed apex on jaws and vomer, numerous pharyngeal teeth with rounded apex and caniniform. Posterior margin of preoperculum serrated, including angle. Operculum with two flat spines, subperculum serrated at upper margin. Branchiostegal rays long and thin. Spiniform rays of dorsalis thin, third and fourth rays longest, first and second spiniform rays of anal short, third long. Tail slightly forked. Scales large, weakly ctenoid.

Line drawing from Sorbini 1975, p. 179:

Identified by oilshale using Sorbini 1975.
