I purchased an immature P. nigricolor roughly a month ago. He has finally hooked out, & his coloration appears to be that of P. platyomma (Hot pinkish). Thoughts?

I just had a consultation with Mr. Google and he says that's the coloring for this species.

Thanks. I just had to double check & be sure, as he was purchased as a nigricolor. Yet, he lacks the coloration of a nigricolor. Here's a snap of my male nigricolor. The difference is fairly apparent.

Google quite frequently returns mixed up results so I'd hardly call that a reliable source of photo-identifying (already a dubious identification method). For example, looking up a particular species of Pamphobeteus often brings up pictures obviously different species of Pampho. Google image search B.smithi--it doesn't take long for auratum and eventually even boehmei to show up and B.smithi is pretty basic. Realistically if the OP is that unsure of which species he has, he should hold off on breeding him and wait to hear from those who've had MM Pamphos in their care.

I've owned Pamphos MMs & AF. This specific specimen is believed to platyomma based on its appearance in comparison to that of a P. Nigricolor.

From what I recall Pamphobeteus platyomma is not an official species yet, so it's Pamphobeteus sp Platyomma due to some importation debacle that was an entirely different species. No type specimen has been collected for this species yet[P.sp Platyomma] and even people with P.nigricolor have to question their species as there has been some recent debate that the spider in the hobby called nigricolor is not really nigricolor as once again there is some difference from the type specimen but who knows if it's just genetic variation or an actual species difference. Photo identification is a terrible way to identify Pamphobeteus as color from camera are different and even the limited blood lines available in the hobby have some color variation. If the seller is trust worthy than if they say it's nigricolor it probably is, but if you aren't sure than be a responsible owner and don't breed him.

Female will eat the sac, even if he does and manages to get one. On top of all that, the offspring will be infertile.

Not always true, just look at the muddied Brachypelma species, they're breeding just fine.

Though as I said, if it was sold as nigricolor (albeit probably the hobby form), then that's probably what it is

Don't forget these are not Brachypelma :)

Yes but just because some hybrids are in-fertile doesn't mean all are, Pamphobeteus species have some area overlap so some natural (and possibly fertile) hybrids aren't out of the question.

A person, who has studied them in the wild and knows them very well, shared with me that the females will eat the sacs due to sensing some sort of pheromone imbalance. I guess we need studies on the matter to confirm or deny.

Hmmm. Yours is much lighter than mine. . . But mine is lighter than P. Nigricolor. I'm even more confused than I was initially lol. There has to be a way to distinguish the difference.

Some species can be told apart via spermathecae (which your male does not have) or emboli shape (which requires you to either maim the animal or get very detailed shots), and there are some in the trade that don't even have a described type specimen; you may figure out what it is not but you won't know what it is.

I would love to see more papers on tarantulas too, I just always hold the view that life doesn't act how we want it to, none the less fertile hybrids or not the pamph shouldn't be bred if there are doubts to what it is.

Agreed. It was label P. Nigricolor right up until the ultimate molt. I recieved it as a penultimate male. I'm not sure how easy it is to mislabel or If lids got switched during a feeding session prior to me purchasing him. Very possible though. He's really pretty. I gotta figure out what he is so he won't go to waste.

ID'ing a Pamphobeteus ( or any spider really) by color is a horrible way to identify a spider.

Later, Tom

This. Pamphoheteus are especially hard to identify, given the mess they are and how identical males are when mature. :)

The extent that there are in fact sp. that can be determined by color quite easily & others that can't.
