A crematogaster species most likely.

Looks like Crematogaster to me.

[AnthonyP163]

Probably Crematogaster pilosa. 

[Aaron567]

Seems most likely to be Crematogaster cerasi or lineolata (very similar species), especially with how large she is and the fact that you found in her the pool, presumably during the day? C. cerasi/lineolata will fly during late morning/midday while most other Crematogaster tend to fly during very early morning or dusk. Her large size also checks out. She has long enough propodeal spines that ashmeadi, another common black species, can probably be ruled out.

Workers are required to distinguish cerasi and lineolata, though.
