Identification
ramburii vs barberi:
In Rambur's Forktail the antehumeral stripe is narrow, wide in Desert Forktail.
In Rambur's the black markings on the dorsal side of the abdominal segments are straight-edged on the sides of the segments.
In the Desert the distal ends of the black markings on the abdominal segments are invaded by the ventral orange color. This causes the black markings to look torpedo shaped in a dorsal view and to show a distal indentation in a lateral view.
In Rambur's, abdominal segment 8 is completely blue while only the bottom of 9 is blue, though on pg. 111 of D&D of the West, Paulson states in his Rambur's Forktail account that some populations at the far western edge of the U.S. range have all of S9 blue.
In the Desert, abdominal segments 8 and 9 are completely blue.
