Neotype (designated by Pitts et al. 2009 ): California, Palm Springs (UMSP). Diagnosis . MALE. The male of this species can easily be recognized by having the marginal cell much shorter than the stigma as measured along the costal vein, and two pair of mesosternal processes forming a square, with the anterior pair much more obvious than the posterior pair. Also, the mandibles are deeply emarginate along the ventral margin, but the mandible narrows towards the apex (see Pitts 2007 : Fig. 67). Genitalia are illustrated by Pitts et al. (2009 : Fig. 18 ). FEMALE. Unknown. Material examined. Type material. Neotype of O. quadrispinosa : California, Palm Springs, 1 May 1933 , at light, Theo. Zschokke ( UMSP ). Other material. Nevada, Nye Co., AMNWR: Non-dune site 5: 2 ♂, LT, 13.VI.2008 , NFB & DAT, 1 ♂, LT, 26-28.V.2009 , 1 ♂, LT, 23-25.VI.2009 , NFB. Distribution. USA (Arizona, California and Nevada). Activity. Males were active in late spring (late May through June). Remarks. Odontophotopsis quadrispinosa were too rarely encountered to determine their habitat preference. Four O. quadrispinosa males were collected in May and June at light traps. Thirty-five O. quadrispinosa males were found at the NTS via light traps, mammal trap and berlese funnel ( Ferguson 1967 ). This species is rare throughout its range and the taxonomy of this species is discussed in Pitts et al. (2009) . This species can be difficult to identify, because the mesosternal processes are weak and sometimes difficult to observe. As such, this species could be confused as a species of Sphaeropthalma Blake, 1871 , but the genitalia are distinct.
