Lobster – Wikipedia

Hoploparia McCoy, Lower Cretaceous Valanginian —Miocene is, by far, the most diverse clawed lobster genus foasil or Recent ; 49 species are known. The genus has been interpreted intuitively to be morphologically primitive and ancestral to some or many modern nephropid genera.

One issue is the difficulty in characterizing i. For Hoplopariaand far more than for other lobster genera, many characters show variable character states.

A second issue is that the morphologies of some Recent genera e. Both issues stem from an originally ambiguous diagnosis of Hoploparia that has been variously expanded in de facto fashion to the point that, today, nobody really knows what Hoploparia means.

Cladistic analyses herein indicate that Hoploparia is paraphyletic and, therefore, support the intuitive judgement that Hoploparia is a wastebasket genus.

This paper, the first species-level cladistic analysis of Hoplopariais not intended to be the sole basis for taxonomic revision but hephropidae, instead, intended to generate discussion among lobster fkssil.

Hopefully, this discussion will fossi forth additional characters for cladistic analysis and other new insights that may lead to better supported cladograms addressing lobster taxonomy.
