Ammopelmatus kelsoensis, commonly known as the Kelso Jerusalem cricket, [2] is a species of insect in the family Stenopelmatidae.
The genus Ammopelmatus differs from other genera of stenopelmatine crickets in the following characters: [2] Leg characters, such as the form of spines and spurs, are important for differentiating species in this genus.
Ammopelmatus kelsoensis has short, spatulate apical tibial spurs and calcars.
Ammopelmatus muwu can be distinguished from A. kelsoensis by the curved apical spur on the internal margin of the fore tibia, the hind tibia with the first tooth on the internal margin, and first major tooth on the external margin of the hind tibia short and blunt.
The short, robust legs, with their reduced spines and spurs, are well-adapted for an arenicolous, or burrow-dwelling existence.
