DistributionAustralia (Western Australia)

Type locality: "Australia." Emended to Southern Australia by Cogger et al., 1983a: 234.  
Reproductionovovivparous (Wilson & Swan 2013; but oviparous according to Cogger 2014) 
TypesHolotype: NMBA 2190, a 395 mm male. 
DiagnosisDiagnosis: “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) 

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. 
EtymologyPresumably named after the two colors on the dorsal and ventral side of the species.
