Resumen
The new species Halegrapha paulseniana Luch & Lücking is described from Hawaii, which constitutes the first report of the genus for this archipelago. The new species differs from the most similar taxon, H. mexicana, in the much larger lirellae featuring an apically complete, thin thalline margin, and from all other species in the genus by its laterally mostly uncarbonized excipulum. We provide nomenclatural updates for the 70 species of lirellate Graphidaceae reported from Hawaii so far, introducing the following nomenclatural novelties: Allographa gracilescens (Redinger) Luch & Lücking, comb. & stat. nov., Fissurina homichlodes (Redinger) Luch & Lücking, comb. nov., Fissurina stromatoides (H. Magn.) Luch & Lücking, comb. nov., Fissurina zahlbruckneriana Luch & Lücking, nom. nov., Phaeographis caesiohians (Nyl.) Luch & Lücking, comb. nov., Phaeographis faurieana (Zahlbr.) Luch & Lücking, comb. nov., Phaeographis fulgurata (Fée) Luch & Lücking, comb. nov., Phaeographis oscitans (Tuck.) Luch & Lücking, comb. nov., Phaeographis rhodoplaca (Müll. Arg.) Luch & Lücking, comb. nov., Platygramme kaalensis (Tuck.) Luch & Lücking, comb. & stat. nov., Platygramme tumulata (Nyl.) Luch & Lücking, comb. nov. and Sarcographa dendroides (Leight.) Tabaquero, Bawingan & Lücking, comb. nov. (validated from an earlier, intended new combination that was not validly published).
