Just to re-visit the conversation about the Hysterocrates sp. "Niger Delta". It was concluded that hobbyists believe this is a variant of H. gigas. Here are two pics with a good one showing a 5" adult female 7-days post-molt. Note the greenish-black carapace. One thing that I can say about this species is that unlike typical H. gigas imported the last 25 yrs., this species don't get the "rusty red" coloration pre-molt. They stay black-brown with a lighter shade before the molt and are darker after the molt with the greenish-black carapace. Opinions about this species are welcomed. I wonder is this is NOT H. gigas and definitely not H. crassipes or H. laticeps, but another Hysterocrates in the genus.

I just got my 2nd sac produced from this species with a captive-breeding this past winter. Fun times cupping up about 150+ slings next week. Another female produced a sac last year around 160 slings.

What does Hysterocrates celerierae look like?
It's range is in the Ivory Coast and Burkina Faso according to:
Bariev T.B.1, Sherwood D.2* 2024. First records of Hysterocrates celerierae (Smith, 1990) from Burkina Faso (Aranei: Theraphosidae) // Invertebrate Zoology. Vol.21. No.1: 94–96

The H. sp. "Niger Delta" are supposed to have been collected from the coastal region (inland rainforest) of Nigeria and possibly the tip of SW Cameroon coastal region of inland rainforest.
Regardless of what it is or isn’t, it is undoubtedly a very attractive tarantula!!

I am really curious to see what the Hysterocrates sp. “Ghana” that were given to me end up looking like as adults as well!

Let's see a good pic of this " Hysterocrates sp. “Ghana”. :)

That's really interesting. It's hard to definitely say H. gigas as it does look a little different in some way and as you say you have noticed different colors pre and post molt, prehaps this could be something. It would be difficult to say where it was collected as the Niger delta and s.w Cameroon are very far apart and the hobby Hysterocrates can be found around the Cameroon/ Nigeria border..

You also have to hope that this is a true species and not a hybrid of laticeps or gigas or crassipes. Even reputable sellers are selling mis identied spiders and I'm sure there are cross breeds now sadly. I guess if they was wild caught then they should be a wild species. I guess we can see now the importance of knowing where it's collected as it really is some challenge to get a definitive answer on the species. Prehaps it would be good to compare it to Gigas as it does seem to have most resemblance to this..

I think Ray Posted a picture of H. celeriae or the type of it.

That's amazing, would be good to see the growth stages!

So I dont have a photo of them outside of the sling stage, just now pushing 2+inches about I think. I have to rehouse into bigger delicup soon so I can try and get some high res shots then.

This is the look now after a recent molt (5oz delicup)


I think I took some good dslr photos, possibly even a decent macro stack, recently after the molt as well but havent pulled them off of the SD card yet I dont believe. If I have any I will post them!

That's amazing, would be good to see the growth stages!
And yes I agree!! It will likely help as theres a fair deal of comparisons for others that are not described/labeled that could help.
I asked for photos of the mother that laid the sac but havent gotten them yet. But I am not resigned to the fact thats still not possible to attain since I am in contact with the person.

Also I don't believe either of you have seen this but when I got this guy I made a thread so I could keep track of documenting it through all of its life stages, since I was the only person I am aware of with a sling of this "Ghana" locale "species".


I also have the most recent molt to sex, still in the backlog, so there that too to hope for to document! Fingers crossed there may be the ability to compare spermathecae!

That's awesome. It will be really interesting to see how it looks growing up and how) if it's different to other species. It would be amazing to see the mother of your sling or the spermathicae. Also the spiniation of the palp and leg 1 would be good to see and compare to other Hysterocrates. It would be good to understand if H. laticeps is the same as species Benin and there's a possibility it's range could extend into Ghana too. As 2e have seen with H. celeriae they single species can colonise huge areas. The sp Ghana reminds me mostly of Hysterocrates crassipes at this young stage..

@Paul Osullivan @xenesthis

Here's a photo I just managed to get of it. Going to attempt to get some more focusing on leg1 and palp as suggested, and potentially a decent focus stack, when it calms down a bit and allows me to try and get some more.

That's a great photo. The 4th legs do appear slim still, it's good to see how this one will progress! Yea prehaps when it's a bit bigger you could compare to some of Andrew Smith drawings of Hysterocrates. Maybe it will match something, although if it's from Ghana I don't think any have been collected or examined from there thats published. Do you think it looks alike to H. Laticeps or even closer to Ghana.. sp. Benin? Prehaps start with these 🙂
