Characters 33—35 are rarely, if ever, observable on fossil lobsters. From a nephhropidae, systematic standpoint, this suggests nephropiade that both Nephropides and Eunephrops should be made junior synonyms of Hoplopariaor that Hoploparia should be rediagnosed in a more restricted fashion, one congruent with ranges of morphologic variation in Recent genera.

This leaves foasil characters as parsimony informative. Archived from the original on October 4, We used 16 of the better known better preserved Hoploparia species that represented the range of morphologic variation in the genus.

In acknowledging that Hoploparia is paraphyletic, the traditional systematist might narrow the diagnosis of Hoplopariacreating new genera for species thereby excluded. Rescaled, weighted Bremer support values for the resolved nodes are shown on the cladogram.
