The mid-Cambrian (Drumian) centropleurid trilobite 'Luhops' and its relatives from the Abbey Shale formation near Nuneaton, central England

Mature and juvenile specimens of Luhops expectans (Barrande) are described from strata in the English Midlands lying near the boundary between the agnostoid zones of Tomagnostus fissus and Hypagnostus parvifrons. Clarella groenwalli Howell and Poulsen is probably a synonym of L. expectans. Other centropleurid trilobites from the same strata include Clarella impar (Hicks) and Luhops coquus sp. nov. Centropleura pugnax Illing, formerly assigned to Clarella and Luhops, is returned to Centropleura; an elongated thorax is tentatively assigned to the species.
