Identification
Note the laterally flattened metasoma. Members of the subfamily Ichneumoninae (like Gnamptopelta) generally do not have this character. I am almost certain this is an ophionine, specifically Thyreodon atricolor (a parasitoid of sphingids). Members of Ophioninae always possess a laterally flattened metasoma. I also have a feeling most of the Gnamptopelta images in the guide are misidentified Thyreodon. The only Gnamptopelta species I agree with so far is this one: 63229. See how the metasoma is NOT laterally flattened? Contrast that image with ophionines (including Thyreodon). See the similarity?

Remarks
"Although most members of the huge family Ichneumonidae are difficult to identify, this large species is an easily recognized, day active, slow flying parasitoid of sphinx moth caterpillars."
