Abstract

The agnostids from the Lower Llanvirn shales of the Southern Central-Iberian Zone (Mounts of Toledo, Villuercas and Almadén district) are described. Seven localities are new for Ordovician agnostids and two are revised. Three new species, belonging to the genera Geragnostella and Geragnostus, are described: Geragnostella gilcidae n. sp., Geragnostus hispanicus n. sp. and Geragnostus ninhursagae n. sp. The new names Geragnostus pilleti nom. nov. and Geragnostus abdullaevi nom. nov. are proposed to rename, respectively, the species G. howelli PILLET, 1978 and G. elongatus ABDULLAEV, 1972, regarded herein as junior objective homonyms of other previously defined species.
