Investigations based on DNA sequence data (R. P. Roberts 2002; Roberts and L. E. Urbatsch 2004) failed to support the monophyly of <i>Tonestus</i> in the sense of G. L. Nesom and D. R. Morgan (1990). Evolutionary affinities of <i>Toiyabea</i> appear to be with <i>Petradoria</i>. Close affinity of <i>Toiyabea alpina</i> to <i>Tonestus eximius</i> and <i>Lorandersonia peirsonii</i> suggested by morphology is not supported thus far by sequence data.</p> |tables= |references= }}<!-- --><!-- -->{{#Taxon: name=Toiyabea |author=Lowell E.
