Helminthoglyptaphim, and
Helminthoglyptotes in a phylogenetic clas-
sification rejecting formal categorical ranks;
he suggested that the name Helminthoglyp-
tales could be considered equivalent to Hel-
minthoglyptini by a "hypothetical systematist
concerned with expressing [his] results within
the Linnean hierarchy".
