Thanks for your input Lou. The researchers admit in there paper that goodei is a species that formed out of hybridyzation between mcallii and platyrhinos. The study area is isolated by the Colorado and Gila rivers so gene flo is restricted. The visible characters for identifying goodei are a more circular dorsal pattern (intermidiate between mcallii and platyrhinos), mostly white vental (like mcallii), double fringes (like mcallii) intermidiate horn structure with an extra temporal horn. The problem is the researchers failed to include the naturally occuring hybrids in CA. I know of 3 locations (North west Coachella Valley, Northeast Borrego Springs and Ocotillo where hybrids occur in CA that fit the description of goodei.Are these isolated populations of Goodei?
Here are examples of 2 different CA specimens that fit the goodei description.
