Yes, Rhopalogaster sp., female. Female Rhopalogaster much more commonly seen in field than males; but latter needed (w/ genitalia) for ID. Very nice find Jeff; these usually seen only at BL during night.
Thanks much Eric. Wish I would have spent more time trying to get pics of these. Saw several, but they were all up high and still pretty wary. I also made the mistake of not taking my 180mm lens on the trip.
