Odontophotopsis (Periphotopsis) mamata Schuster, 1958: 60 ,

3. Holotype: Arizona, Ehrenberg (UMSP).

Diagnosis. MALE. This species can be easily recognized by the distinct mesosternal processes, which are made up of large glabrous longitudinal swellings located on either side of the midline. Genitalia are illustrated in Fig. 5 with the paramere having a characteristic bend at approximately 2/3 the free length from the base, and the mandibles can be viewed in Pitts et al. (2010a: Fig. 10 ). FEMALE. Unknown.

Distribution. USA (Arizona, California and Nevada).

Activity. Males were active from late spring through mid-autumn (late May through mid-October).

Remarks. Odontophotopsis mamata were collected significantly more often in non-sand dune habitats than in sand dune habitats (U=25, p=0.01). Three hundred three O. mamata males were collected from May through October at light and pitfall traps. One hundred fifty-one O. mamata males were found at the NTS from June through September via light trapping, pitfall trapping and net collecting ( Ferguson 1967, Allred 1973). The taxonomy of this species is discussed in further detail in Pitts et al. (2009).
