Status Mooi & David (1996: p. 915) commented: "We do not here consider the taxonomically confused genus Carnarechinus Mironov, 1978 a urechinid. In spite of recent additions to the literature on this genus (Mironov, 1993), its affinities remain difficult to establish. We will also not consider Cystechinus clypeatus Agassiz, 1879 [the type-species of the genus], a species known only from fragments collected by the Challenger. The systematic confusion surrounding these fragments (see Mortensen, 1907 for a summary) means that we may never know whether they represent a single species, or several."
Despite the recent progress in echinoid systematics its relation to other urechinids still remains unclear, but preliminary molecular data (Petrov et al. 2012) indicate that it is a basal member of the clade.
