Is this Heterometrus longimanus?

[Arachnopotamus Rex]

Yea there's some differences between female and male granulation, but that's a Heterometrus silenus.

Ah ok, which one is the female? heavy granulation (your pics)? or light granulation (my pic)?

Yours looks female based on the operculum, mine is a male.

Here is a pic of my 5i H.silenus (suspected male). It seems to be similar in development to yours.

Can you zoom in on the cheek granulation, chela, and operculum for comparison?

I just got another one.
This new one has the most chill temperment ever, literally ZERO defensiveness/aggression, it even lets me pet it with a paintbrush (figured this out when trying to get it to move into its new enclosure).
Whereas the first one is a little ball of hate and gets mad if i so much as look at it from 2 feet away.

Interestingly, the angry one seems enthralled with the new one, and as soon as it saw the new one it stopped being aggressive.
I'm hoping they are opposite sexes so I can breed them, but i haven't had the chance to check its underside just yet.

Update: I fed both scorpions 2 crickets yesterday, and today the male refused his third cricket, but the female kept trying to shove as much in her mouth as possible and stole what was intended for the male after he abandoned them (she has eaten 6 total at this point, grabbing 3 at a time)

Normally I give them 3 crickets each within the span of 2 days once every weekend, but this weekend she's extra hungry and active, and he just wants to lay around and do nothing.

Maybe she's gravid? Do I keep giving her more until she wont take any? Or do I cut her off from her sudden unhinged gluttony?
Up until now they both refused food after eating 3 so I never really had to think about this.

Also they didnt have names before today, so I named them Munchlax and Snorlax.

At last count I believe there are about five or six species being sold as Asian Forest Scorpion.

at present 8 with one offshoot

H. longimanus - Borneo
H. spinifer. - Malaysian
H. silenus Asia General
H laoticus Viet Nam, Laos
H. laevitugus Thailand
H. petersii Singapore
H. thorelli Myanmar
H. glaucus Mursala Island

Javanimetrus cyaneus. (Asian Blue, Java) recently split from heterometrus

The company I work with at shows typically sells H. longimanus and every one I have ever dealt with has been a total cupcake. We have 2 batches of CB slings so I am waiting until they are big enough to sex, because I could breed them and they'd be different lines (I don't line breed)

Backgrounder. In recent years Borneo has been undergoing intensive deforestation by foreign countries. So it comes as no surprise that H. Longimanus is now common in the animal trade. https://wwf.panda.org/discover/knowledge_hub/where_we_work/borneo_forests/borneo_deforestation/

I am assuming lots of WC of each of the genus is happening because of deforestation. Thanks for the background info. The company I work with is captive breeding them and we had 2 batches (2 Moms) of babies. I will probably
get 1 of each sex, one from one clutch, one from the other and attempt to breed them to avoid line breeding

Probably Heterometrus silenus. H. longimanus is very uncommon in the US, though silenus are often labeled by wholesalers or retailers as longimanus.

Leave the male in for a week or so then remove him. Make sure there's a large flat rock in there with him or somewhere to deposit the spermatephore. Keep female isolated until she gives birth (probably already gravid).

Heterometrus mysorensis and Gigantometrus swammerdammi are also in that group.

Noted! thank you

 

[adam james]

Heterometrus mysorensis and Gigantometrus swammerdammi are also in that group.

I will add Gigantometrus titanicus and Deccanometrus bengalensis to this list.

 

[Matt Man]

Heterometrus mysorensis and Gigantometrus swammerdammi are also in that group.

I would file both of those under "Offshoots" like Javanimetrus cyaneus. Both have "Giant" in their names
and both have been broken away from the genus. Heterometrus mysorensis is now Chersonesonetrus tristis I think.
Gigantometrus titanicus is the only other species in that genus, so placed again as an outlier.

and in the comments about things probably being H. spinier, people are captive breeding longimanus
they are being displaced by deforestation in Borneo and WC specimens have been put into breeding programs.

They have typically longer claws than spinifer and different granulation.
