Papuan Satyridae genitalia
Hello,
Can anyone confidently determine whether this Papuan Satyridae is male or female?
I have the feeling it's a female and if so... that would be new to science for this species.
I am not so used to work on small Satyridae so I'd prefer a confirmation.
Cheers
Olivier

Re: Papuan Satyridae genitalia
I have no idea about Satyrinae genitalia, but it is worth comparing your specimen with males to see if there is presence/absence of secondary sexual wing characters such as male androconial scales/patches/tufts. If males of the same species have these but your specimen does not then it is likely to be a female.

For the moment, they are still on the spreading board and I don't see much differences, but this abdomen without any clasper.
Satyridae often have nearly no sexual dimorphism so it is not so easy.
I guess a DNA test or a genitalia preparation will be needed to be 100% sure.

Just take a fine-tipped artist paint brush, and very gently dust off the scales to see if it has claspers or anal palps. For best results, cut the brush at about the 50% point, so that the bristles are a little stiffer for removing the scales. And be careful about knocking off the abdomen.wollastoni wrote: ↑Mon Dec 11, 2023 5:28 pm For the moment, they are still on the spreading board and I don't see much differences, but this abdomen without any clasper.

If I had to take a wild guess - I'd say male. I think I see an upward-jutting valvae approaching the uncas at the top.
