Hi guys,

today I get a real captive breed litter of Androctonus finitimus from Hyderabad, Pakistan(Thar desert)
The parents were grown up in captivity & now they reproduce successfully.

What a cool species you got there!

Congratz Carlos! That's a great achievement and a step towards getting these in the hobby.

Does anyone know what is the white part? This is an Androctonus Mauretanicus 5instar male.

From what I can make out from the picture, it does not seem like a bacteria infection...

Is it dented inwards or something?

And is the scorpion eating regularly and active?

Mr.Rolando Teruel has commented some information about the triangular whitish part, please refer to the link below(if posting a link here is allowed).

As these posts in facebook sometimes may be deleted, and not everybody has access, I'm copying it here for future reference:

Dr. Rolando Teruel @ Facebook, July 2013 wrote:

Juan Xean, if you are referring to the whitish triangular patch on the sternite V (this is the formal name of the third ventral plate of the scorpion abdomen), it is nothing to worry of. It is a supposedly glandular structure many scorpions have (mostly males), and it is a normal part of their body. It is called "smooth patch" or "whitish patch", by the way.

Hi, I would like to know is there a way to easily differentiate Androctonus bicolor, crassicauda, and mauritanicus? These 3 species are looking so familiar.

Furthermore, i have A.bicolor from two countries, and the colouration is so different. One has a very dark black color and the other one has a shallow black color.

They do look similar. They are usually easily identifiable at adulthood, or at least, after 4/5.instar. I'll try to put up some comparative pictures shortly.

Yes, there can be some variation in color morphs among, A.bicolor. I believe you have seen the "chocolate one"?

Also there is the "aeneas" ones that is slightly smaller very glossy black.

I haven't seen choco one.. haha too much to see and learn..

Androctonous bicolor breeding project vid 1

You can see the color variation of black (on the male) and brownish (on the female).

Hi all,
another question recently, how to differentiate all the sub species of Androctonus Australis?

such as AA hector (dark chela and metasoma), AA lybicus, AA tunisia, AA tunisia hector?

Thanks in advance!

by **Testosterosaurus** Tue Aug 20, 2013 4:01 pm

Hi Juan,

there is not subspecies presenting in these species.
Vachon(1948 & 1952) grouped A.australis in 3 colormorphs:

dark pincers & metasomasegments 4 & 5 = A.a. "hector"
dark metasomasegments 4 & 5 = A.a. "libycus"
uniformly yellowish = A.a. "australis"

But there ist no "black & wihte" between these morphs. Some populations are more or less darker or rather lighter in these zones.

Regards,
Carlos:D

Hi,
so you meant that Androctonus australis has 3 colormorphs..

is A.a. "australis" equal to A.a. "Tunisia"?

here is the specimen I had recently, what morph is it? These pictures are taken with and without flash.

I follow valid descriptions & no designed names. But there is a cretain grade of intaspecific variation, in color & shape. Sometimes more bulky or smaller & sometimes slender appearance. It is because of the big distribution based on adaption.
But I think this taxon will be spilt in future. CIBIO works on a genetic study of north african A.spp. & will give further information about this genus.

This is a adult male - from Tunisia, I guess. Uniformly yellow with dimmish pincers.
