Parapercis okamurai Kamohara is very close to P. aurantiaca, both 

 having palatine teeth, whereas all the new species described herein 

 lack palatine teeth. 



Since the recently discovered new species were unknown when 

 Cantwell made his revision (loc. cit), I have extensively expanded 

 and modified his "Key to the Species of Parapercis." Differences in 

 counts between the two keys result from new counts by me, the 

 correction of a few errors in the Cantwell key, and additional color 

 descriptions. The following- key distinguishes 32 species.
