than long, unlike Cybocephalus new species 3. In males, the basal plate (Fig. 6-23) and

median lobe (Figs. 6-21 and 6-22) are easily distinguished from all other species.

 Geographic distribution. Durango, Durango; San Luis Potosi, Ciudad del Maiz

 Material examined. Mexico: San Luis Potosi: Ciudad del Maiz, 24-V-1996, coll.

 Remarks. This species is typically found east of the Mississippi River in the

United States, however specimens have been collected west of the Mississippi along the

gulf coast (Smith and Cave 2006a). Therefore, it is not surprising that this species is

found in Mexico. For a detailed host list north of Mexico see Smith and Cave (2006a).

For a description of the species see Smith and Cave (2006a).

 Diagnosis. Male and female are black. The antennal club is as large as or larger

than the eye (Fig. 6-25), separating this species from all other Mexican Cybocephalus. In

males, the basal plate (Fig. 6-28) and median lobe (Figs. 6-26 and 6-27) are easily

distinguished from all other species.
