However, examination of the type material and new collecting by the authors indicate that a taxonomic review has become necessary. Two new species of <i>Bradocryphaeus</i> are recorded, <i>B. vanherlei</i> sp. nov. and <i>B. neptuni</i> sp. nov.; one additional species, B. sp. 20, is known from the pygidium alone. New material is recorded of <i>Bradocryphaeus maillieuxi</i> (Richter & Richter), which has hitherto been scantily illustrated in the literature. The cephalon of <i>Heliopyge helios</i> (Richter & Richter) is redescribed on the basis of new specimens and its holotype pygidium refigured.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Late Devonian (Frasnian) Asteropygine trilobites from the Frasnes area, southern border of Dinant synclinorium, Belgium","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Trilobita, Acastidae, Devonian, Ardennes","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2015-02-26","DateCreate":"2012-12-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000297182400001","VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":221315,"PubliDate":2011,"Pagination":"109-128","XtraPublOfAnaID":null,"ISBN":null,"Volume":"14","Issue":"3-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45707,"SerRR":"Geologica Belgica.
