McCarthy (1987) proposed that the relatively simple scale microornamentation in sea snakes (Laticauda colubrina: brachylamellate basally, cellular polygonal imbricate apically; McCarthy 1987, Price and Kelly, 1989) when compared to the relatively more complex microornamentation of terrestrial elapids was "perhaps connected with an anti-fouling strategy".

Leg IV: stouter and larger than tritonymph; trochanter weakly granulate; femur not granulate; lateral margins of patella more granulate than ventral and dorsal margins; patella 2.39-2.70 longer than femur; tibia slightly curved basally, as long as patella or slightly shorter than patella (0.97-1.00); tarsus clearly shorter than tibia, with weak granules; most setae with one lateral and few terminal denticulations, patella with one simple median seta, tibia with simple and long terminal setae, tarsus with basal denticulate setae.
