Pelegrina proterva - male

Pelegrina proterva - Male
Licking County, Ohio, USA
Embolus, terminal rami of Left palp; ventral view. See here for ID reference.

I really like the lighting here, but the specular reflections are driving me nuts as they can be a bit misleading.

14 images in Helicon Focus. Olympus NeoSPlan20x, darkfield/reflected, NFK2.5x photo eyepeice, uncropped.

what parts are these?
Can you label this and the other one? I have no idea what I'm looking at here.

Yikes...
Guess I was in a hurry and overlooked the description. I just updated both descriptions, and replaced this image with one containing an overview map.

The other photo is a retrolateral view of the left palpus. Sometimes referred to as "the boxing gloves".

In adult male spiders the palps are modified into secondary genitalia used during copulatory sperm transfer. It's also the single most important body part for use in obtaining a positive identification of most adult male spiders.

This photo is a closer view of same, showing additional detail of the embolus and terminal rami.

even more useful...
if I had the terms correct. These are ventral aspect, not retrolateral as I described. If I rolled the palp to the left 90deg., that would be a retrolateral view. Sorry for any confusion.
