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.
一个 Paraglossus 的种如 Rennis& Hoese(1985) 所鉴定与 Paraglossus 的所有被描述的种区分藉由跟随组合特征: 深色的侧面身体斑纹不存在, 前鳃盖骨孔不存在, 在纵向的从胸鳍上方基底到尾鳍基底的系列，胸鳍鳍条 19-21 ，分段的尾鳍鳍条 7+6 中的 100个或更多鳞片, 鳞片非重迭成瓦状的, 黑色的尾部斑点通常子三角形的 (一件标本用斑点概略矩形), 第一背鳍的薄膜依附于在雄性与雌性中的第二背鳍鳍了, 成熟的雄性有背鳍棘 3-5絲狀的大約長度相等, 生鮮地雄性有背外側地跑的狹窄的黃色斑紋沿著來自頭部到尾鰭的身體。
Only known specimens were found on mud and rubble substrates in shallow inshore waters of less than 1.5 m in depth (Ref. 52789).
