Distribution	Australia (Western Australia) Type locality: "Australia." Emended to Southern Australia by Cogger et al., 1983a: 234.
Reproduction	ovovivparous (Wilson & Swan 2013; but oviparous according to Cogger 2014)
Types	Holotype: NMBA 2190, a 395 mm male.
Diagnosis	Diagnosis: “A group of small to moderate-sized species lacking contrasting dark head coloring (apart from R. nigrostriatus), with glossy midbody scales in 15 rows, anal and subcaudals entire, eye small with black iris. indistinguishable from pupil. Head, slightly to moderately depressed, no canthus. Distinguished externally from some superficially similar species of Suta by deeper, blunter head, absence of contrasting colour pattern (except black-headed R. nigrostriatus) and/or longer tails (subcaudal counts exceed 40 in most species {not boschmai], versus 40 or fewer in most Suta). Further distinguished from other genera by the unique karyotypes (not present in bicolor), 2n = 36 (20 M, 16 M) or 40.” (Hutchinson 1990: 403) Additional details (1037 characters) are available for collaborators and contributors.

Comment	Venomous! Synonymy: Wallach et al. 2014 included the species of Cryptophis in Rhinoplocephalus. Type species: Rhinoplocephalus bicolor MÜLLER 1885: 690 is the type species of the genus Rhinoplocephalus MÜLLER 1885.
Etymology	Presumably named after the two colors on the dorsal and ventral side of the species.
