Hi
Once, P. siphonorhina had species status, then it was seen as a subspecies of guttatus and, in 2006 i think (unfortunately, I can't find the article at the moment), it recieved species status again. Fact is, that it's not just a morph of guttatus, because there's a consistent difference in the nasalia and the toe lamellas between the two types.
The thing with the phenotypical overlap is pretty difficult to answer. If I compare my animals with some that are defined for sure as guttatus, there's no obvious difference in habit, their bodies look the same, except the two points mentioned above. To distinguish them by colour is not certain either because they are able to change it pretty well. So the only safe way to determine guttatus or siphonorhina is by counting nasal scales and toe lamellas.
To know what species one keeps is important because they do not inhabit the same habitat (says the mentioned article, published once in REPTILIA)
Siphonorhinas favour really dry areas, while guttatus prefer areas with a little higher humidity, like oases.
That means one cannot keep them adequate unless he knows what (sub-)species he's got.
