| Abstract |
The Frasnian representatives of Asteropyginae in the Frasnes area (south Belgium) have long been relatively well-documented when compared to other trilobites in the Devonian of the Ardennes (Belgium, northern France). However, examination of the type material and new collecting by the authors indicate that a taxonomic review has become necessary. Two new species of Bradocryphaeus are recorded, B. vanherlei sp. nov. and B. neptuni sp. nov.; one additional species, B. sp. 20, is known from the pygidium alone. New material is recorded of Bradocryphaeus maillieuxi (Richter & Richter), which has hitherto been scantily illustrated in the literature. The cephalon of Heliopyge helios (Richter & Richter) is redescribed on the basis of new specimens and its holotype pygidium refigured. |
