Etymology: Symphurus: Greek, syn, symphysis = grown together + Greek, oura = tail (Ref. 45335); polylepis: Name from Greek 'poly' meaning many, and 'lepis' for scale, referring to the greater number of longitudinal scale rows compared with that of similar species of shallow-water tonguefishes.

Dorsale zachte stralen (totaal) : 84 - 87; Anale zachte stralen: 68 - 74; Wervels: 46 - 48. is distinguished from all congeners by the combination of: ID pattern1-2-2-2-2 ; caudal-fin rays 12; vertebrae, 9 (3 +6) abdominal, 46-48 total; hypurals 4; D 84-87, A 68-74; longitudinal scale rows 88-94; transverse scale rows 32-34; scale rows on head posterior to lower orbit 17-19; fleshy ridge well developed on posterior part of ocular-side lower jaw; fleshy membrane covering both eyes; anterior margin of upper eye usually slightly in advance of anterior margin of lower eye; with fleshy flap continuous between ocular-side anterior nostril and anterior region of lower eye; upper head lobe is usually wider than lower head lobe; head length moderately long (HL = 21.9-23.8% of SL) and relatively large postorbital length (POL = 15.7-16.6% of SL, 69.3-73.3% of HL); preanal length relatively short (PAL = 23.5-24.6% of SL); snout short (SNL = 16.0-18.3% of HL, SNL/ED = 1.44-1.86), rounded to obliquely blunt anteriorly; head length usually shorter than head width (HW/HL= 1.02-1.14); dorsal-fin origin in posterior position at, or slightly posterior to, vertical through posterior margin of upper eye; predorsal length moderately long (PDL = 5.7-7.1% of SL; 24.4-31.4% of HL). Colouration: ocular side uniformly yellow to light-brown, blind side uniformly white, both sides with obvious dermal spots on bases of anteriormost dorsal- and anal-fin rays, and peritoneum bluish-black (Ref. 126065).
Cross section: flattened.
More accurate information about geographic distribution, bathymetric distribution and substrata where this species is found needed to better understand the ecology, distribution and life history of this species (Ref. 126065).
