DIAGNOSIS: Same as generic diagnosis.

DESCRIPTION: Coloration, surface, vestiture, structure, and genitalia: As in generic description.

MEASUREMENTS: MALE (holotype /range; N=4): total body length 2.46/2.55-2.70, clypeus to cuneus length 1.75/1.70-1.90, body width 1.06/1.10-1.30, pronotal length 0.43/0.45, head width 0.81/ 0.75-0.83, pronotal width 0.98/0.85-1.00, antennal segment lengths : AS I 0.35/0.40, AS II 0.60/0.60-0.65 , AS III 0.35/0.35-0.37 , AS IV 0.36/ 0.35, and interocular distance 0.47/0.45-0.47 .

FEMALE (range; N=3): total body length 2.2–2.65, clypeus to cuneus length 1.6-1.9, pronotal length 0.45-0.47, head width 0.83-0.87, pronotal width 0.93-0.97, antennal segment lengths: AS I 0.40-0.43, AS II 0.6-0.63, AS III 0.35-0.37, AS IV 0.35, and interocular distance 0.45-0.5.

ETYMOLOGY: Named after the late Leonard A. Kelton, whose work in Durango, Mexico, led to the capture of these specimens.

HOST: The majority of the specimens collected of this species were labeled as collected on sotol, genus Dasylirion sp. ( Asparagales : Asparagaceae : Notinoideae). There are currently about 22 species of sotol, of which two are known from Durango: D. durangense Trel. , and D. simplex Trel. (WSCP 2018). This group of plants is native to Mexico, all have tough leaves with serrated edges that provide a natural defense.
