Short description

Vertebrae: 103. Mastacembelus liberiensis has a blunt snout (Ref. 55095). The posterior angle of the lips is situated from about below the horizontal middle of the posterior nare up to below the anterior border of the eye (Ref. 55095). Upper corner of gill opening slightly anterior to, or below, dorsal point of pectoral-fin base, both points clearly anterior to ventral point of pectoral-fin base; dorsal point of pectoral-fin base situated largely above upper corner of gill opening (Ref. 55095). Gill opening closed for about half or entire vertical distance between the dorsal and ventral edge of the pectoral-fin base (Ref. 55095). The lateral-line is yellowish-white and can be continuous in the anterior part from the head to up to one pectoral-fin length beyond the posterior edge of the pectoral fin; the remaining, more posterior part of the lateral line is always clearly discontinuous (Ref. 55095). Preanal length negatively allometric, postanal length positively allometris (Ref. 55095). A relatively high number of dorsal spines, with spines increasing in size from first to last; one additional very short spine hidden under the skin and situated anterior to the base of the first dorsal-fin ray (Ref. 55095). Two externally visible anal spines, the first smaller than the second; one additional very short spine, hidden under the skin, and situated anterior to the base of the first anal-fin ray (Ref. 55095). The preopercular spine number varies from 1L/1R up to 5L/5R (Ref. 55095).
