Diagnosis

Sonora fasciata can be distinguished from all other Sonora except for S. straminea and S. cincta by the presence of an elongated rostrum. Sonora fasciata is sympatric or narrowly allopatric with S. straminea and S. cincta . Sonora fasciata can be distinguished from S. straminea by the lack of apical maculations. There are no simple morphological measurements to distinguish S. fasciata and S. cincta , but Holm (2008) presented a formula of head squamation to distinguish these two taxa. Geographic range may in fact be the most reliable way to distinguish S. fasciata from S. cincta (see below).

Variation

This snake has both geographic colour pattern variation and colour polymorphism. In southern populations, both banded and unbanded specimens can be found in a single population. All specimens from Baja California Norte are banded.

Distribution

Sonora fasciata is found from the central Baja California Peninsula at least as far north as Las Tres Virgenes to southern Baja California Sur near El Triunfo ( Figure 4 View Figure 4 ) .

Remarks

This species is in the subgenus Chilomeniscus .
