Nevadia Walcott, 1910 Type species. N. weeksi Walcott, 1910. Discussion. Nevadia saupeae n. sp. was assigned to Nevadia based on its possession of key diagnostic features including the lack of a macropleural third thoracic segment, the relatively long (as opposed to species of Nevadella ) (sag.) LA, and its possession of straight SO and S2 (additional discussion of criteria for assigning species to Nevadia as opposed to Nevadella is given in Lieberman 2001). Important distinctions between N. saupeae and other species of Nevadia / Nevadella include a very broad (tr.) extraocular area, very short (exsag.) genal spines (about the length [sag.] of LO), and presence of a preglabellar field.
