Length 4.5–5.5 (mean 5.0) mm, width 2.5–3.2 (mean 2.8) mm (n= 20 specimens ). Trichiotes seriatus Casey can be separated from Trichiotes lightfooti based on the diagnostic characters enumerated in the T. lightfooti diagnosis and key. Remarks. This species appears to be fairly widespread in the Chihuahuan desert ( Fig. 1 ), though uncommon in collections.
