Tippmann, F.F. 1956. Uber einige, vorwiegend palaearktische Cerambyciden und Beschreibung neuer Formen. Bollettino del Laboratorio di Zoologia Generale e Agraria della facolta agraria in Portici, 33: 473-492.
Remarks:
The name following the binomen was not expressly given infrasubspecific rank and the work did not indicate unambiguously that the name was infrasubspecific, therefore, it is deemed a subspecies and available. Although published as "de maggii", we have removed the space following Article 32.5 (ICZN, 1999).
