Head finely punctured, semiopaque. Mesonotum aciculate; pleurae shining, impunctate; a broad oblique reddish band proceeding from the tegulse to the hind coxae. Metathorax finely punctured, aciculate in the middle above. Abdomen closely and somewhat strongly punctured, the apices of the segments shining. Sheaths of the ovipositor thick, densely pilose, a little shorter than the tibiae.” Distribution. Mexico .
