In his comprehensive study of the Paraonidae, in general, and of Aricidea jeffreysii (Mcintosh), in particular, Cerruti (1909) synonymized Levensenia Mésnil, 1897, with Paraonis Grube, 1873, and recognized the latter and Aricidea Webster, 1879, as the two valid genera of the family. In addition, he reduced Cirrophorus Ehlers, 1908, to subgeneric status in the genus Aricidea and proposed a new subgenus, Paraonides, for the genus Paraonis.
This classification of the Paraonidae was followed for more than fifty years, and was recognized by Fauvel (1927), E. and C. Berkeley (1956), Hartman (1959), Day (1961), and Pettibone (1963). Hartman (1957), in addition to proposing a third subgenus, Aedicira, for the genus Aricidea, redefined Paraonis (Paraonides) Cerruti.
It remained for Day (1963) to raise the subgenera to generic rank with the statement (p. 420) that "...as the whole family includes some fifty species it is suggested that the subgenera be given full generic rank." Hartman (1965a), with some few exceptions, concurred with Day as to the generic status of the former subgenera and proposed two new genera, Aparaonis and Paradoneis, the latter including Paraonides as earlier redefined (Hartman, 1957); all seven genera were listed in Hartman's catalogue supplement (Hartman, 1965b). Laubier (1965, p. 469), in his report of the presence of Cirrophorus in the Mediterranean, followed Day in the recognition of genera, with the comment that "Ce point de vue parait justifié...," and Glémarec (1966), in describing a new species of Paradoneis from Brittany also accepted Day's judgment. Finally, Day (1967) continued the recognition of the former subgenera as genera, with the exception of Paradoneis Hartman which he returned to Paraonides Cerruti. Thus, according to some authors there are presently seven, six, or two genera in the family Paraonidae, and generic criteria are the presence or absence of modified setae in neuropodia or notopodia and/or the presence or absence of a median prostomial antenna.
