Gen. Acanthogonatus Karsch, 1880 [urn:lsid:amnh.org:spidergen:00104]
N.B.: transferred here from the Barychelidae and considered a senior synonym of Tryssothele Simon, 1902 (considered a senior synonym of Chubutia Mello-Leitão, 1940b: 3, type C. notata Mello-Leitão, 1940 by Gerschman & Schiapelli, 1970a: 152) by Raven, 1985a: 83.
Transferred to other genera:
A. antillensis (F. O. P.-Cambridge, 1898) -- see Fufius under Cyrtaucheniidae.
A. argentina (Simon, 1897) -- see Stenoterommata.
In synonymy:
A. australis (Chamberlin, 1917) = A. pissii (Simon, 1889) (Gerschman & Schiapelli, 1968: 27, sub Tryssothele).
A. guttulatus (Simon, 1886, T from Stenoterommata) = A. subcalpeianus (Nicolet, 1849) (Goloboff, 1995: 7.
A. latastei (Simon, 1902) = A. pissii (Simon, 1889) (Gerschman & Schiapelli, 1968: 27, sub Tryssothele).
A. segnis (Simon, 1886) = A. francki Karsch, 1880 (Goloboff, 1995: 104).
A. venosus (Mello-Leitão, 1936, T from Aphantopelma=Thalerommata) = A. pissii (Simon, 1889) (Goloboff, 1995: 91).
Nomen dubium:
A. gounellei (Simon, 1886c: 573, j, Brazil, T from Stenoterommata by Raven, 1985a: 107) -- Goloboff, 1995: 76 (but see Mello-Leitão, 1923a: 57).

it looks like at least some of the spiders in the hobby as Acanthogonatus are not. develops to be posted here
NBond1986
My particular spiders have not been identified as non-Acanthogonatus.
We're just questioning whether or not they are in fact the vilches species, if that's what you're referring to.
cacoseraph
oh, my bad. yeah that was. i'm kind of busy today =P
Bastian Drolshagen
hi,
just wanted to let you guys know, that Acanthogonatus sp. might be pretty venomous, since the spiders examined regarding their venom by Bücherl (who stated they were Trechona venosa) were Acanthogonatus subcalpeianus/campanae.
Raven (1985) says A. campanae and Pedroso & Baptista (2004) claim those were A. subcalpeianus...
So mybe not a good idea to play with those
BTW.: There´s a study regarding the venom of Trechona sp. claiming their bite causes only local pain... volunteers first
cacoseraph
hmm
like Poecilotheria level?
or Atrox/Hadronyche?
Poeci level i'm willing to chance playign with... Atrox/Hadronyche... probably not
Bastian Drolshagen
As Trechona venosa is supposed to be
cacoseraph
hmm
seems like massive confusion exists. if someone gives me one i'll take a bite. i've never had necrotoxin injected into me before =P
NBond1986
wow, and i had my male running all over me yesterday.
he's a big spazzzz.....
the females are much calmer.
Bastian Drolshagen
hi,
as I mentioned: I wouldn´t play with such a thing... besides that I never touch any of my spiders except for my large and calm B. albopilosum females. Since nobody really knows how venomous Dipluridae are I use tweezers etc. to work in their tanks and cricket boxes/glasses to catch them. Most of my Theraphosidae are categorized as "aggressive" - Pterinochilus, Ceratogyrus, Stromatopelma etc. <-- Nothing I would try to touch
The toxin is probably no necrotoxin, but neurotoxin...
What
You have never met Caco.
He will play with ANYTHING.
cacoseraph
hmmm
fairly mysterious neurotoxin is not really my bag though
it may seem like i play with stupid stuff... and well, i guess i *do*
but... generally i am either confident (from reading as much as i can) that the venom is not *too* hideous or the creature is exceptionally unlikely to bite me
when i can't really say either or both... i think i am going to have to go with discretion being the better part of valor. and just hold them for photo shoots. hehehe
