This image shows a female specimen labelled as
Rhipiphorus vierecki from the California Academy of Sciences insect collection.
I'm uploading it here in conjunction with this
post to illustrate the clear presence of a serrate outer edge of the mesotibia in this specimen.
The serration can be better seen in the full-size
2078 x 1662 pixel image here.
Please see
aforementioned post for full details.
