I just saw a picture of a male Ceratogyrus species. It didnt have a horn. Which raised the question, Do only females get and keep the 'Horn' on the central apodeme?

are you sure it was a Ceratogyrus sp. then? I've never even heard of a Ceratogyrus sp that didn't have a horn, though it could have molted off.

Might have been the angle but im almost sure there was no horn.

The picture was lable Ceratogyrus sp. male.

well chances are it was there. I hear the males have smaller horns than the sp. Can you described what it looked like? Some have itty bitty horns which are more like mounds such as c. meridionalis or c. pillansi

It looked like any other Ceratogyrus sp. Maybe the horn was just obscurred by the angle of the picture? I think that I saw the picture right here on the boards.

Oh, wow. I was planning on getting a marshalli. Hope i get a female, lol. Is only only mature males who dont display it, or just males in general?

Of the 10 currently recognised Ceratogyrus species, only 4 possesses a fovea with protuberance ("horn").

Know for a fact that darlingi(bechuanicus) and brachycephalus males have horns. Think that marshalli has a small protuberance but not 100% sure. As was said, there are a number of Ceratogyrus species with no horn on male or female

Thats really neat! Im still going to get a marshalli though, hehe. I never knew that males didnt grow the horn. Thats one characteristic to help determine the sex, lol.

Some Ceratogyrus spp just have a little button there, not a horn. There are others with no unusual structures on their carapace at all. As far as which are or are not in the hobby and which specific species have what sort of horn I can't help you there.

Male bechuanicus have horns as well (I currently have a mature male).

Are you sure it's a Ceratogyrus and not a Pterinochilus chordatus or lugardi?

That can easily be determined as Ceratogyrus spp. possess a pale subabdominal band over the booklung area (only exception is C. paulseni but I doubt that this species is available in pet stores), opposed to the mentioned Pterinochilus spp. which lack this subabdominal band.
