Diffs between N.Chromatus & A.Genic?

[thumpersalley]

Im having a very hard time seeing the differences between these 2 species, can anyone please post side by side pics or tell me what the differences are? (yes, Ive done a search here & looked on other sites, no help)

Well, for one, they are different species.

 

[nicholo85]

sometimes, I find the only difference between Tx and Ty is the name, and sometimes the adult size.

So really, in my perspective, the only difference is being able to say "Ive got this RARE Tx" as opposed to saying "oh ive got this really nice looking Ty".

Thanks for that, I would never have guessed. :clap:
Really, I could use some info here. :?

 

[thumpersalley]

I would like some specific info so when I intruduce people to my Ts, I dont sound like a complete lamen idiot saying:

"Oh yeah, I have these spiders but I dont know what kind they are, hell I dont even know what care they require."

Thanks to other person who responded with a good point of view.

Chromatus seems to have more of an Attitude problem than A.Genic

they have very differnt banding for one
the geniculata is prodominantly black whereas the chromatus is grey with red setae on the abdomen
geniculata get bigger by about an inch or so

a.genic

n.chromatus

Thank you "Plunge"

Thank you very much for the pics. Im still not sure. I have posted pics under Tarantula I.D, one person N.Chromatus. Could you look at see if that is indeed correct? I tried to post the pics with this post but it said too big but let me post on the I.D forum. Go figure. Kim

Haha, there are differences for sure, from the genetic level all the way up. I think a better way to express the OP's intention is to say "how can I tell a N chromatus from an A geniculata."

Besides overall size and the intensity of the abdomen color, the thing that frequently jumps out is carapace color. Right?

 

[spiderfield]

Absolutely, size of both species aside, difference in carapace color is obvious between the two.

 

[barabootom]

The most obvious difference in juvies and adults is the color of the carapace. The chromatus has a tan/buff colored carapace while the geniculata has a dark colored carapace.

The abdomen of the chromatus has red hairs against a lighter color and the genic has red hairs against a dark abdomen.

The striping is very different and you can see the genic has almost white banding while the chromatus has a buff colored banding.

The geniculata will grow larger, oftentimes reaching 8 inches. The chromatus usually tops out at 7 inches. The geniculata will generally be more bulky than the chromatus when it gets older.

The chelicerae (where the fangs are) are also different colors.

Hope this helps.

LOL! Master of the obvious, lol.

They're both about as docile as it gets. I have both (mistake, should have gone old world and nasty). We're talking new world species, folks.

 

[moose35]

the tarantula you posted in the id section is nhandu chromatus.

Thank you all for the help!

yep 100% chromatus no doubt about it

 

[equuskat]

In addition to the visible differences that have been pointed out, these species have very differently shaped reproductive parts (spermethecae).

Docile ? I have a Genic that attacks anything that lands in her cage. Not sure a would call that docile.
