Upper lip with papillae and without cleft anteriorly and m Upper lip with papillae and without cleft anteriorly and midlaterally. Second dorsal fin with 1 spine and 10 segmented rays. The general pattern of the female resembles that of a female Stiphodon, with a yellowish body background and a light dusky black band extending midlaterally from posterior of pectoral base and ending as a spot posterior to hypural base. Scales in lateral series 55-59, in transverse forward 14-16 and in predorsal 18-20.idlaterally. Second dorsal fin with 1 spine and 10 segmented rays.

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).
