HOLOTYPE. Probably in Paris Museum, collected by M. Verreaux [inaequifasciatus]
|Comment||Synonymy after PETERS & OREJAS-MIRANDA 1970 and CEI 1993. S. inaequifasciatus (from Paraguay) is a synonym fide Paul Smith, pers. comm., 4 May 2014 and 22 Aug 2014). Based on the original description Peters (1960) noted that all but one of the holotype's characters have been reported from aberrant individuals of S. vagans, and that it also shares characters in common with S. neuwiedi. It is therefore possible that S. inaequifasciatus is conspecific with one of these two species, in which case the name S. inaequifasciatus would have priority (Peters 1960). In the absence of additional specimens and reliable information on its provenance its appropriate taxonomic status cannot be verified and the holotype ("Probably in the Paris Museum" - Peters 1960) has not been located. Peters (1960) recommends "discarding" the name on this basis, but despite this recommendation the name S. inaequifasciatus continues to be used to refer to a valid species in checklists for Brazil and (erroneously) Paraguay." (P. Bowles, pers. comm., 3 Mar 2015)|
Distribution: "This species is known from a single specimen from "Sudamerica", probably collected in Brazil but never subsequently recorded there. A specimen from Paraguay originally assigned to this species (Cope 1862) was later included in the type series of the new species Sibynomorphus turgidus by the same author (Cope 1868). Recent examination of this individual confirmed its identity as S. turgidus (P. Cacciali, unpubl. data), and the holotype is therefore the only example of S. inaequifasciatus known to exist.
The type locality of Cochliophagus inaequifasciatus was repord to be in South America, “doubtfully from Brazil”; apart from that the distribution is unknown. The specimen from Paraguay has been reported by Cope (fide Peters 1960).
Diet: primarily molluscs, snails, slugs (Santos et al. 2017).
