White (1991) noted that the P3 of this species differs from that of other species of Alilepus in its small size, comparable to that of Aluralagus virginiae. It also differed in that the innermost part of the posterior external reentrant widened and was deflected anteriorly. Although similar in size to Aluralagus virginiae, it differs in having the anterior lateral reentrant more deeply incised and in the characters of the posterior external reentrant noted above.
Ruez (2007) indicated that Alilepus wilsoni matches the morphology of Aluralagus virginiae while differing in several aspects from other species of Alilepus and the closely related Pratilepus.
