Mygalomorphae of California, USA


This thread is to discuss the non-Theraphosidae mygalomorphae spiders of California, USA

here is the first set of Google Image Searches for the non-thereaphosidae
if the google image search link just says the genus name then there were no species level pics available
if the google image search link is an italic genus then there is no search to genus level (see second set)


FAMILY GENUS SPECIES urlGiS
ANTRODIAETIDAE Aliatypus aquilonius Aliatypus
ANTRODIAETIDAE Aliatypus californicus Aliatypus californicus
ANTRODIAETIDAE Aliatypus erebus Aliatypus

ANTRODIAETIDAE Aliatypus gulosus Aliatypus

AWESOME 31 page paper on Aliatypus genus in California!

VERY cool pics of myg hunting in So CAL!

California Calisoga sp.

California Calisoga sp.


Ok, one of the reasons i am interested in CA myg's is this species!

that is a SILVER TARANTULA*!!!

* note, if you strictly define "tarantula=Theraphosidae", then this is NOT a tarantula. also note: if this is C. longitarsus then Platnick has listed under Brachythele longitarus for the like, ~usual reasons


edit:
i really debated posting about this species... after all, if i stimulate demand that means the price goes up... but then i thought, if that is the expense of hopefully getting the sp. firmly established in the hobby (a la A. francki's, but more cb'ing!!!) it would be worth it. and i can always drive and camp and catch my own, heh

hi, the Mecicobothriidae are pretty small spiders, which look pretty much like Dipluridae but can be distinguished from those by their longitudinal fovea. As far as I know they also built funnelwebs, which end in a silkened tube.

ah, thanks :)

one project i would like to work on is putting together a dichotomous key for all California non-Theraphosidae mygalomorphae. stuff like that will really help!


i love how small some of these species can get! the smallest are ~ Cyriocosmus elegans size, it seems like :)

hi,
there´re even smaller mygalomorph spiders (not in CA, but also in the USA). For example Microhexura montivaga, which grows up to 3,8mm BL.
You could use parts of Ravens work (1985) to ID spiders to family or even genus, and other literature for further ID. There´s a revision of the Mecicobothriidae on the net with which it should be possible to ID all Mecicobothriidae to species level.

Cyrtaucheniidae Aptostichus species
freshly molted adult female, around 1.5-2" DLS

diferent female with eggsac. eggsac didn't make it for whatever reason

http://i21.photobucket.com/albums/b...RanchoCuc/Aptostichus_RanchoCuc04_eggsacb.jpg


Mecicobothriidae Megahexura fulva
these mygs are quite small. adult females are under 1"DLS and MM can be even smaller
burrow entrance

here is a size comparison shot of a huge MM my buddy found. it died fairly quickly after we caught it before i had made up my mind to try to mate it to one of my females


they are fairly rough in their mating, at least from the males. other similar species apparently do similar rough handling
