Adult distinguished from the very similar Cerastis robertsoni by differences in genitalia: in males of cornuta, the vesica is straight beyond the basal turn; in females of cornuta, the corpus bursae is constricted posteriorly, the appendix bursae is even in width throughout its length, and the ductus bursae is shorter.
