. The specific epithet, scytobrachion, is ancient Greek for "leather armed", but also honors Dionysius Scytobrachion, a mythographer who chronicled the mythical history of North Africa. The holotype and all referred remains were found in a single quarry at the base of the Irohalene Mudstone Member of the Timezgadiouine Formation in the northeastern Argana Basin, 2.9 kilometres (1.8 mi) east of Imziln, Morocco. Diodorus can be distinguished from other
silesaurids by the presence of anteriorly-canted teeth that decrease in size towards the
anterior end of the dentary and a distinct lateral ridge running parallel to the dentary
alveolar margin. In a phylogenetic analysis, Diodorus was found to be the sister taxon to the Brazilian silesaurid Sacisaurus
