Sphaeropthalma (Micromutilla) becki Ferguson, 1967: 9 ,

3. Holotype: Nevada, Nye County, Hillside, 0.85 mi NNW Mercury (NMNH).

Diagnosis. MALE. This species is recognized by the deeply excised mandible with the tooth forming an oblique angle (see Pitts et al. 2009: Fig. 45), the lack of mesosternal processes, the marginal cell shorter than the stigma, the first segment of the metasoma petiolate with the second segment, and the genitalia with a short cylindrical cuspis (see Pitts et al. 2009: Fig. 2 View FIGURES 2 – 11 ). FEMALE. Unknown.

Distribution. USA (Arizona, California and Nevada).

Activity. Males were active from late spring throughout the summer (June through September).

Remarks. Sphaeropthalma becki were distributed uniformly over sand dune and non-dune habitats (U=13.5, p>0.2). Four hundred eighty-eight S. becki males were collected from late May through September via light, pitfall and malaise trapping. Eighteen S. becki males were found at the NTS from July through August via light and pitfall trapping ( Ferguson 1967).
