C.marshalli sexual dimorphism

[PhilBugs]

Apologies if I've put this in the wrong place, there wasn't an appropriate category in the sexing forum as far as I could see (I'm a newbie, go easy on me).

As Ceratogyrus marshalli is sexually dimorphic with females having a horn and males having a nub, is the horn on this 2-3" specimen big enough to confirm 'her' as female? I've not kept the species before so I'm not sure how early it can be used as a way of ascertaining the sex.

it hard to tell from that angle

Yes, I suppose so. Unfortunately, it quickly bolted for its burrow before I could get a picture from a lower perspective. I will have to try again another time or hope the next moult remains intact.

Thanks for the reply.

Well, I have a marshalli confirmed male of around the same size, he’s a lot more spindly and with more of a nub on his head than a horn. I’d say get more front/side angle when you can, but looks female compared to mine lol

My male marshalli is shown here.

Congrats! Looks pretty female to me honestly, definitely a more pronounced horn than mine at an even smaller size.

got another picture of my male on the rare occasion he’s out of his burrow (atleast halfway). He’s a little bigger than your gal but I can tell yours is not male lol

 

[PhilBugs]

Yes. It's quite obviously flatter on him. It's good to see the sexual dimorphism. Thanks.
