Lema (1979) proposed that the name bilineatus should be dropped from usage, replacing it with the name spegazzinii, which was followed by some authors (e.g., Cabral & Cacciali 2015), however, the two forms are now considered separate species.

Phalotris tricolor

Tri-coloured Diadem Snake, Tri-coloured Collared Snake

Dreifarbige Diademnatter

Trefarvet Diademsnog

1854 Elapomorphus tricolor Dumeril, Bibron & Dumeril
Phalotris tricolor Ferrarezzi 1993

Remarks: Previously included punctatus and the populations now assigned to matogrossensis. Records from Brazil refer to matogrossensis (Lema, D'Agostini & Cappellari 2005; Martins & Lema 2017). Nevertheless, Martins & Lema (2017) plotted a record in Mato Grosso in their distribution map, but presumably in error, since they stated that matogrossensis is the only species of the tricolor group found in Brazil. Presence in Argentina needs confirmation, since earlier records are based on misidentifications (Martins & Lema 2017).
Distribution: Bolivia, Paraguay.
