Toiyabea was originally described as Haplopappus and later transferred to Tonestus. Investigations based on DNA sequence data (R. P. Roberts 2002; Roberts and L. E. Urbatsch 2004) failed to support the monophyly of Tonestus in the sense of G. L. Nesom and D. R. Morgan (1990). Evolutionary affinities of Toiyabea appear to be with Petradoria. Close affinity of Toiyabea alpina to Tonestus eximius and Lorandersonia peirsonii suggested by morphology is not supported thus far by sequence data.
