New Brachypelma sp ????????Hello AllI got this from a scientist from Mexico. "Con lo referente a la Aphonopelma anax, me gustaría comentarte que Locht ha hecho una revisión del los holtipos de la especie y ahora se engloba en Brachypelma, todas sus carácterísticas son de este género, así que pasa a ser Brachypelma anax" this is the Babel translation "With referring to the Aphonopelma anax, I would like comentarte that Locht has made a revision of the holtipos of the species and now is included in Brachypelma, all characteristics are of this sort, so it passes to be Brachypelma anax " I asked the guy for the papers o a link to that revision. As son as I get it I will post it here. regards francisco |

Yay
Great new stuff. |

Here's a slightly clearer translation:
"Con lo referente a la Aphonopelma anax, me gustaría comentarte que Locht ha hecho una revisión del los holtipos de la especie y ahora se engloba en Brachypelma, todas sus carácterísticas son de este género, así que pasa a ser Brachypelma anax" With regard to Aphonopelma anax, I would like to comment that Locht has revised the holotypes of the species and now it is included in Brachypelma, all its characteristics are of this genus, and that is how it becomes Brachypelma anax. Very cool, 'Cisco! |

So now we have an official native brachy? Very cool. I can't help but wonder if any other Aphonopelmas might be eventually added to Brachypelma. After all, anax seems so similar to many others we have. |

they have been trying this with several species of Ap's for awhile now but its hypityical at best, since true Ap's are distinct from brachys with carapace shapes a slopes and hair textures (and we are not even going into geno mapping yet and venom protein breakdowns between the 2 species)... so i highly doubt it being revised anytime soon.... especially this species because of the caparisons between both Aphonopelma a. and Brachyplma albiceps...comparable pics(even from photos) clearly distinct the 2 from each other if using the (standard) mature pics which people on some other boards are failing to realize, even if pointed out.....sorry just my 2cents….
wondering if I have seen the same report already refuted???? maybe not, hey frisco if you get it, mind if I get a copy…thanks wayne and ya im back ::lol:: and i belive it was settled that not all were alike but enough..... |

Hello,
UPDATE I heard from my friend in Mexico and it has been confirmed that A anax is now B anax. It just need to be anounced officialy Wayne, as soon as I get my hands on the revison papers I will send you a copy. regards to all. |

hey,
pls also send me: drolshagen@dipluridae.de |

my guess is that aphonopelma and brachypelma will be massively restructured once genetic studies and what not get to be more standard and accepted than the classical morphological way that has been used to do most of the taxo work to date |
| Bastian Drolshagen |
hi,
not sure about this. ATM they´re distinguished by the presence/abscence of scopula prolateral on Trochanter I and Femur I and retrolateral on trochanter of pedipalps. Since Brachypelmides has been synonymized with Brachypelma the shape of the spermathecae (2 stalks vs 1) is not a keyfeature anymore. Wonder what the genes will say... I mean, those are quite evident morphological features and genes don´t tell everything. |

my understanding was brachypelmides was erected to get around the cites on brachypelma species by some german dude (Raven?) and then some mexican lady put the boot down on it and moved all the brachypelmides to brachypelma |

You gotta watch out for those mexican ladies

mmmmm mexican ladies (((insert homer drool and gurgle sounds))) |

has anyone read any of Dr. Brent Hendrixsons papers??? there seems to be a bigger divide between the 2 species than mere cosmetics..... any hoot, he is going to be at the ATS conf...if anyone is going to be going i'd be interested in his papers and would send you out the cash to send thm out to me....
Dr. Brent Hendrixson will present: The potential utility of DNA-based taxonomy in Aphonopelma: a preliminary investigation |
| cacoseraph |
oh, let me clarify... i don't particularily expect too many species to jump B->A and vice versa... i DO expect B and A to be broken into more and smaller genera based on actual cladogram results
... like, maybe the dwarf aphonopelma get their own genus if they all have a common ancestor and were not just what is it called, convergent evolution |

Here's a bit more information, taken from Prentice (1997, Theraphosidae of the Mojave Desert west and north of the Colorado River (Araneae, Mygalomorphae, Theraphosidae). The Journal of Arachnology 25: 137-176. The character separating Aphonopelma and Brachypelma species is inidcated.
Definition of Aphonopelma: The genus Aphonopelma is distinguished from all other genera by the following combination of characters: (1) no known external organs of stridulation (males do stridulate, however); (2) normal, relatively slender (hair-like or spiniform) plumose setae on prolateral trochanter and femur of leg I and on the retrolateral coxa and trochanter of palp (in some species these setae are finely plumose); no `large' plumose (lanciform or spatulate) setae such as those on the prolaterobasal femur of leg I in [Brachypelma] or those on the prolateral coxa of leg I in Grammostola; (3) type I urticating hair only; (4) corresponding segments of all legs approximately the same width in females; femur III in males of some species laterally swollen; (5) scopula of tarsus IV usually 148 entire, if divided then only partially and narrowly by line of setae; (6) setae of prolateral coxa I hairlike and not basally swollen (known only in small species), spiniform and basally swollen, or distinctly thornlike (apically filiform), with all forms at least distally plumose; (7) metatarsus I flexing against lower process of tibial spur, with either apex of spur contacting ventral surface of metatarsus or outer edge of spur in the apical half contacting the prolateral metatarsus; (  lower (outer) process of tibial spur curving prolaterodistally and widening apically, usually equipped with at least one apical or preapical megaspine, and upper (inner) shorter process less stout basally, relatively uniform in diameter throughout its length, and equipped on its inner surface with at least one (several not uncommon) stout, basally articulated megaspine.

any updates on this???
anyone see the write ups that A. smith and R. gallon did on these??? from a recent trip to mexico to ID and picture Brachy's in the wild some were found on the sides of trees some 5 meters up!!! semi aboreal anyone ::lol::.........they even made a vid which is worth a gander to all Brachy fans.... |

@Caco: Raven is Australian.
The guy you mean is Schmidt... but don´t say that name too loud you´re gonna get sued if you do ^^ A lot of the Schmidt papers are not worth the paper they´re printed on. |
