Etymology: Rhinolepadichthys: The suffix 'rhino', meaning nose, in combination with the genus Lepadichthys, refers to the pointed snout in members of this genus, which distinguishes the new genus from Lepadichthys (sensu stricto); polyastrous: Name from combination of the New Greek 'polys' and 'astrous'” meaning 'many stars'” referring to
the many characteristic yellow dots on the body.

Dorsale zachte stralen (totaal) : 10 - 11; Anale zachte stralen: 9. This species is distinguished from other members of the Lepadichthys lineatus.
complex by the following set of characters: body comparatively slender, its depth 10.8-14.9 (mean 13.1) % SL; adhesive disc elliptical, its length 17.0-20.6 (18.7) and width 11.6-13.9 (12.9) % SL, ratio of length to width 1.26-1.61; anus positioned somewhat anteriorly, the pre-anus length and disc to anus length 62.0-68.3 (65.8) and 21.6- 28.9 (25.8) % SL, respectively; snout tip is directed downward, usually horizontally level with lower margin of eye (lateral view); abdomen with a single yellow stripe along the ventral midline; dorsal and lateral surfaces of body with yellow dots, forming c. six to eight and three to five longitudinal rows, respectively (Ref. 129525),
Cross section: oval.
Partially digested crinoid pinnules were found in the stomach of a specimen suggesting a diet
of L. polyastrous similar to that of L. lineatus (Ref. 129525).
