Measuring from tip of the head (not counting the antennae) to the tip of the abdomen, she is 4 mm.  What is your ruling now, oh wise ant morphologists? :)

I'm quite sure she's Ponera pennsylvanica. H. opacior have a rather blunt petiole, where as this queen has a sharper, more angled one. Not to mention her size; Like Aaron567 pointed out, H. opacior queens are within the 3-3.5mm range, where as this queen is around 4mm, according to drawpositive.

Looks like Ponera pennsylvanica.

I think it’s Ponera.

The petiole is suspiciously thin and tapering; I'm leaning towards Hypoponera opacior on this one. Not recorded from Delaware but is found in some surrounding states so it wouldn't be a surprise to find them there.

 

In this case size would also help reinforce an ID. H. opacior queens are around 3-3.5 mm in length while Ponera pennsylvanica queens are quite a bit larger.
