Size
3.2 - 17.5 mm forewing length(2)
Identification
"A stout, somewhat tapering ovipositor is distinctive for this genus - although some Gelinae (Cryptinae) show a very similar one. But barely one of them combines wholly black body and orange legs; forewing venation is different." – Richard Vernier on photo 251580

Note the absence of a strong indentation of the eye in line with the antennal sockets, present in both Apecthis and Itoplectis.
Remarks
Per Bob Carlson: Releases of the Eurasian and north African Pimpla rufipes (= P. hypochondriaca, P. instigator) were made in New England against Lymantria dispar in the early 1900s (1906, 1907, & 1909(1)), but the species was never established.

The European Pimpla contemplator was later introduced to Nova Scotia in 1964 but likewise was never established.(1)

The Eurasian and north African Pimpla turionellae was introduced several times to Nova Scotia (1950 & 1955); Quebec (1952); Ontario (1935-1937, 1950-1954, 1956, 1958); New England (Massachussets?) (1906-1909); Connecticut, New Jersey, & New York (1935-1938); and Idaho & Minnesota (1937). Only isolated recoveries in Ontario have been known since.(3)(1)
