( Fig. 115 View FIGURE 115 )

Material examined. USA: California: Sutter County: Sutter Buttes [39.2058°N 121.8199°W], 2.iv.1953, J.C. Hall (1♂, 1♀, UCDC) GoogleMaps .

Diagnosis. Males of this species differ from the other members of the M. arcana species group by the mid femur lacking long basiventral setae and hind femur with posterior patch of setae relatively sparse and not brush-like (similar to Fig. 107 View FIGURES 106–109 ).

Distribution and seasonal occurrence. This species is known only from a pair of specimens collected in early April of 1953, from the Sutter Buttes near Yuba City in the Central Valley of northern California ( Fig. 115 View FIGURE 115 ).

Remarks. The male is missing its hypopygium, so we have elected to leave this species undescribed until additional material becomes available for study and type designation.
