We can, but I think we need to look at the geographic boundary between cystignathoides and campi in eastern Mexico so we know where to draw the lines between the two species. The Gruenwald paper doesn't offer any resolution of this. I guess we could make maps that overlap in the area of uncertainty?

So what is currently considered a "cystignathoides" is actually a composite of three species. The next Grunwald paper will shed more light on this as will the chapter in the upcoming book on Reptiles and Amphibians of Mexico. The reality is, Eleutherodactylus campi was never properly sunk, so considering it invalid was never properly justified. The actual cystignathoides are in coastal northern Veracruz, Hidalgo, Puebla south to approximately Cordoba and north to approximately Altamira. The actual campi are lowland and foothills of Nuevo León and lowland Tamaulipas and S. Texas. What is going on in the rest of Texas I don't know... nor do I have the total picture on where those two species "meet". The third species is from highland Tamaulipas, San Luis Potosi and Hidalgo. There is no name associated with this species yet, and it will have to hang out on naturalist as cystignathoides for now.

That looks like a good split of the species. The US range of campi is much wider than what IUCN shows though (much more of Texas and into LA). Our atlas is a better representation. We will need a new common name for cystignathoides. Does Eastern Chirping Frog make sense or does it make more sense to wait for the split of the southern species?

The altamira / tampico population was originally thought to be intergrades, and had a lot to do with the two taxa being synonymized in the first place. They are a weird population, and I don’t have DNA from their. My hunch is that they may be the “high elevation” species or just cystignathoides. I don’t think they look like Campi.

Thanks @sonoran - is this better as a coarse range map - mainly just for reassigning observations post split and giving a general sense for where they occur?

OK split https://www.inaturalist.org/taxon_changes/84401 lots of obs involved so may take a while - thanks sonoran and sandboa!

We also have to work out the common names problem. The name Rio Grande Chirping Frog makes no sense for the southern population and it is the name long associated with the northern population. I elevated Lowland Chirping Frog to the main name for cystignathoides.

@sandboa Tocayo: I am not ready to call the species boundaries that detailed yet... WEST of Cd. Valles, in the hills around Tamasopo, etc... is the new species. Valles itself and to the east is probably campi... but I haven't run DNA from that area. Anything south of Valles pretty quickly will be cystignathoides. The species probably divide the habitat based on moisture. Actually I think Coniophanes in that area do the same shit. For common names... I have no idea. But Rio Grande Chirping Frog should definitely go with campi. Lowland Chirping Frog could work for cystignathoides... although they aren't always lowland and certainly not lower than campi.
