It looks like it could possibly be H. sp.Vietnam. It isn't the best picture and even though we have one of that species, I can't say for sure.so lets play a games.... whats this haplo.
This would be something you would tell us. We have no size reference, so when you try and measure for yourself with a ruler; measure from the front leg on one side, to the back leg of the opposite side. That will give you the D(iagonal)L(eg)S(pan).also size
We keep ours fairly humid. You can achieve this by having a large water dish and limited ventilation, or by wetting some/ a small portion/ a corner or two of the substrate once a week or so. We have that enclosure planted with a large water dish and limited ventilation. The plants get watered roughly every other/ third week. It is pretty humid at all times, but that is not from watering the plants alone. If you don't have a planted enclosure, then moistening the substrate may not be the route for you.and humidity
Then leave it alone. Give it 6+ inches of substrate, start it a burrow in one of the front corners and then leave it in a quiet place. Haplopelmas are obligate burrowers, so when they don't have a burrow or the ability to burrow, it can stress them. It is most likely a W(ild)C(aught) pregnant female and who knows how long it has been here in the states. If it was recently caught and imported, it has had enough stress, now it needs quiet and darkness if you can manage it. When we first bought ours, she was WC, pregnant and super defensive. She stridulated at us the very first night, as we were preparing to put her in her enclosure. She was extremely defensive, but once she made herself a burrow to be able to run and hide in; she doesn't throw threat displays anymore.my roommate brought it home and now its trying to eat me.
