Note: The term Abraxas traces from gnostic religious beliefs, where it is a magic word, combining some form of mystic numerology with comological ideas plus a hierarchy of god-like creatures and/or mystical powers. However, it is often used as a name for the "power above all" or the "highest of all gods" and is then depicted as a male god. This is currently the best evidence for the grammatical gender of the genus name and I therefore regard the genus name as a masculine noun. All adjectival species name epithets therefore must take the masculine form (i.e. the subspecies epithet intensus). However, the nature of "sylvata" is unclear. It is based on the Latin word sylva (an alternative form of silva ("forest, woods"), but is not a proper Latin form. Therefore, I do not regard it as an adjective, but as a form comparable to Roman cognomina. These were also formed irregularly from a basic word (e. g. "Cicero" formed from the word "cicer" (chickpea) as the cognomen for Marcus Tullio Cicero). Thus, I regard "sylvata" as a noun in apposition that does not change its form when combined with different genera.
