Oh.. I thought you were telling me its a male Errm well it appears to have tiny micro ridges and umm there's a like a ridge extended at the very top that's an opaque/white color? You can make it out in the picture.
No, I can't really tell from the photo but you can look and see. Or if you can take a better shot of the rostrum using the macro mode on your camera we can all take a closer look.
First glance I would say female or juvenile. Also, you can tell the species often by counting the plates. Two vs three rows.
Here's a good example of the male.
