Abstract

Two taxa assigned to Psilocara (Trilobita, Olenidae), from the upper part of the Parcha Formation (Incamayo creek, northwestern Argentina), are described. Psilocara liliae n. sp. is characterized by shallow axial and preglabellar furrows, shallow or almost effaced glabellar furrows, moderately narrow fixed cheeks, palpebral lobes with curved outline, and free cheeks without genal spines. Psilocara? sp, has, in addition, a tapered glabella and anelliptical cephalic outline. The occurrence of the genus in this formationgives additional evidence in support of its early Arenigian age.
