|discussion=<p>Species ca. 60 (1 in the flora).</p><!--
--><p>Species of this group were long treated in Cacalia; difficulties with the typification of that name led to its rejection (T. M. Barkley 1999). The genus Koyamacalia was erected by H. Robinson and R. D. Brettell (1973) for the Asiatic “core” of Cacalia, including the single species in the flora area; the name <i>Parasenecio</i> has priority.</p>
