Description of two new Ctenichneumon Thomson species from southern Arizona, USA (Hymenoptera: Ichneumonidae: Ichneumoninae: Ichneumonini)

Ctenichneumon Tomson, 1894 (Hymenoptera: Ichneumonidae: Ichneumoninae: Ichneumonini) is a moderately diverse parasitoid wasp genus with a broad distribution, including 14 described species in the Nearctic region. Here, I advance our knowledge of Nearctic Ctenichneumon by describing two new species, Ctenichneumon elaiodes, new species, and Ctenichneumon hesperis, new species, from the Huachuca Mountains in southeastern Arizona. Diagnostic notes and specimen images are provided to facilitate identifcation
