What family is this wasp? - Myzinum obscurum - Female
Lakeland, Polk County, Florida, USA
June 10, 2005
Size: 24 mm
I thought at first this was a Vespid wasp, but the antennae are too short, much like scollid wasps. I cannot find any ID in this guide or on the net. Please help.

One wasp or two?
Scott, if the other image, with the same sighting date, is this specimen, please link the images.
I would do it for you, since they look the same anyway, but I thought that I should check with you first.

Myzinum obscurum, female
Propodeum has striae on the sides, which distinguishes this from the otherwise similar M. carolinianum.

Moved from Myzinum.

Tiphiid Wasp (Family Tiphiidae)
Wing venation and shape of the compound eyes do not match with Scoliidae. Therefore, Tiphiidae are the only possibility left.
This one species could indeed be new for the Guide. Although reminding of the "classical" Myzinum, namely by the shape of its pygidium (apex of the abdomen), it has much less yellow color among other differences.

I agree.
This is a female Myzinum, possibly M. obscurum. I had a tiphiid expert go through my specimens, and he could only tentatively ID the individuals that looked like this. Males are radically different, being very slender with a prominent "pseudostinger."
