Ceratogyrus species sexual dimorphism

[jpumahinay]

I have read in one of the threads that C.marshali tarantulas are sexually dimorphic (females have horns while males do not).

Can anyone direct me to any link or information that may help me find out if the other ceratogyrus species are sexually dimorphic.

Thanks

Not exactly true, most species of this genus the female has the horn, the males have a much smaller one, often called a button.

There are some species of this genus which don’t have a horn according to a member here. They aren’t found in the hobby maybe in EU, not US

Thank you for the info.

I have 3 ceratogyrus sp. (Marshali, meridionalis and darlingi) i was just curious if these species are sexually dimorphic.

Ceratogyrus meridionalis don't have a horn

Thanks I was pretty sure they didn't, not 100% sure.

At what point does the horn start to appear?
I have a marshalli that I raised from a sling a year ago, I suspect this will be a male as there is no sign of a horn.

Really? I can find Ceratogyrus meridionalis quite easily.

I haven’t been looking too carefully then!!!

Besides who wants a bald Cerato! Cerato without a horn is a weenie.

What size is it now? If I recall correctly, my female developed a horn quite early. I think after one year it should be clear if it develops a horn or a button.

My darlingi is about 2in DLS, horn is quite pronounced. My marshalli, I rarely see him out and about, but the last time i saw it was about 1.5 in horns/nubb is not yet present. My meridionalis, it ripped its molt to shreds, so i was not able to attempt to try to sex it (2 in DLS).
