Morphology | Morphometrics
A species of Paraglossus as diagnosed by Rennis & Hoese (1985) distinguished from all described species of Paraglossus by the following combination of characters: dark lateral body stripe absent, preopercular pores absent, 100 or more scales in longitudinal series from above pectoral-fin base to base of caudal fin, pectoral-fin rays 19-21, segmented caudal-fin rays 7+6, scales nonimbricate, black caudal spot usually sub-triangular (one specimen with spot roughly rectangular), membrane of first dorsal fin attached to second dorsal fin in males and females, mature males with dorsal-fin spines 3-5 filamentous and about equal in length, fresh males with narrow yellow stripe running dorsolaterally along body from head to caudal fin.
Only known specimens were found on mud and rubble substrates in shallow inshore waters of less than 1.5 m in depth (Ref. 52789).
