B. vagans sexing

Our B. vagans molted last night and I just shot a pic - hopefully good enough to sex by. Please explain how you sexed it and feel free to steal pic and draw on it for explanaition :)

Thank you very much!

It's a male. I stole the pic and drew on it. :D Click here. The blue line indicates where the spermathecae would be if it would be a female, in this case it would look like a "flap", but it's missing here (very visible on this B. emilia exuviae - click here). The red line shows what is probably the area of epiandrous fusillae - specialised spinnerets used in making the sperm web, only males have these, they noticeable from the outside, especially in older juveniles/adults.

Thanks, I have been looking at a lot of pics here trying to learn doing this myself and I cam to the same conclusion :) But I still think that it is hard on some females to see the spermathecae...
