Interpretive Summary: The caterpillar-like larvae of sawflies are plant feeders and can cause extensive economic damage to agricultural crops, forests, and ornamental plantings. One exclusively pine-feeding genus is found only in the western United States south to Guatemala, where some species have caused extensive defoliation of ponderosa and pinyon pines. A new species was discovered in Chihuahua, Mexico, defoliating Durango pine. This species is described and separated from the other species of the genus. All six species are characterized and illustrated, and an identification key is given. This will be of help in recognition of these pine-feeding sawflies and will aid U.S. Forest Service personnel and others in their identification.

Technical Abstract: Zadipion ojedae Smith and Sánchez-Martínez, n. sp., reared from larvae feeding on Pinus durangensis in Chihuahua, Mexico, is described, and notes on its life history are provided. Hosts, distributions, and remarks on the other five species of Zadiprion are given, and the females, ovipositors, and male genitalia of all six species are illustrated. An identification key is given for all species.
