for the most part older pumilio were coming from costa rica and nicaragua. they were either "blue jeans", "black jeans", or bri bri. the important thing about knowing the difference is not mixing the two. you are very unlikely to encounter this problem IMO since nearly any pumilio you can get cheaply and easily will be of the panamanian farm raised variety. now it gets interesting since there are frogs like the newer "BJ" imports which should not be mixed with old bloodlines since, although they both are (most likely) CR 'blue jeans", we have no clue whatsoever that they are from the same area and there is a decent bit of speculation which suggests that rather than one continuous BJ population there are multiple different ones (however slightly to our eye). therefore they should be kept separate. and thats just a tiny tip of the pumilio iceberg. locale/ ID confusion is a common problem of the species.
what the caresheets dont say, and what i think both members were trying to illustrate to you is that pumilio ARE different from other dart frogs. they are pretty much the only obligate egg feeder most hobbyists can even get, much less afford. they are slightly more difficult than other frogs, and, rightly, arent suggested for beginners but it can be done. i ALWAYS suggest this be attempted with the supervision of another frogger (at least close by and able to be reached by phone) with pum experience. pretty easy for most of the members here who live in or near big cities. but thats not all of the story. most of the pumilio in the us come from wild caught stock (directly). unlike darts such as azureus or terribilis, which breed readily in captivity and are well represented in captive populations, a stable population of pumilio arent. there are some morphs which are more readily available since the offspring produced are more hardy, or the fresh caught frogs produce an initial boom of offspring, but when the dust settles the vast majority of each morph will be lost, leaving a hand full of frogs to supply the masses. there is a finite # of each morph imported and its our job to do the very best with the animals that were given.
in the end its up to you, its your money and you'll do what you want with it, but make sure, if you choose to take on something like pumilio, to keep researching and asking questions.
