It was recombined as Eubaena hatcheri by Joyce and Lyson (2015).

Diagnosis
ReferenceDiagnosis
E. S. Gaffney 1972None given by Hay who distinguished this species in his key (1908, p. 60) as follows: "Length of anterior lobe 0.92, its width 1.00, of width of bridge, width of hinder lobe 1.04 of width of bridge." It is distinguished by Hay from B. marshi by these criteria and it is distinguished from all other species of Baena by the horizon, "Laramie."
