Modocia whiteleyi (Robison & Babcock, 2011)
Diagnosis
Modocia having a short (sagittal) preglabellar field, narrow palpebral areas, short genal spines, 12 thoracic segments with angular terminations, moderate-sized pygidium with distinct medial notch, and 4 rings in the pygidial axis.
Etymology
After Thomas E. Whiteley, for promoting knowledge of trilobites (Whiteley, Kloc, and Brett, 2002).
Discussion
Modocia whiteleyi differs from all other species of Modocia by having only 12 thoracic segments. It further differs from most Modocia by its short preglabellar field and narrow palpebral areas.
Specimens of this species are illustrated commonly on the Internet as either Modocia hewlisca or M. weeksensis, both of which are taxonomically invalid names (nomina nuda).
