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.
