added note
This basic type, from west of the Great Plains, was described as Trimerotropis agrestis subspecies barnumi by Tinkham in 1960, with other names [gracewileyae and hewitti] to follow for basically the same thing from further west. Otte treated T. barnumi as a distinct species in 1984, with Tinkham's other names as synonyms. There is very little difference between "T. barunumi" and "T. agrestis", but I'm going to separate them the way that Tinkham originally described them here, as subspecies of one species.
Added to this is the fact that T. agrestis merges with T. maritima citrina on the Great Plains with lots of intermediates occuring wherever the habitats of the two meet. So, a good case can be made for calling T. agrestis and T. agrestis barnumi subspecies of T. maritima!

Trimerotropis agrestis
Acually moderately closely related to
Spharagemon
, and
S. collare
may look, behave and sound rather similar (but it has a high pronotal crest cut only once. However, what is most closely related is
Trimerotropis maritima
. Beautiful photo of a beautiful insect! It doesn't show here, but the hind tibia is orange/red, as is the inner side of the hind femur. Wings yellow with a black band. This is very much a creature of sand.
