Redescription of Zinagon chilensis (Silvestri, 1903) from Chile, with a species list of Iulomorphidae from the Southern Hemisphere (Diplopoda: Spirostreptida: Epinannolenidea)

The epinannolenidean diplopod species Zinagon chilensis (Silvestri, 1903) is redescribed based on recently collected ma-terial from Chile, as well as on the re-examination of type specimens of both Iulomorpha chilensis Silvestri, 1903, and Zinagon osorno Chamberlin, 1957. The latter is here designated a junior subjective synonym. A list of the species of thefamily Iulomorphidae is provided, including 15 genera occurring in the Southern Hemisphere, i.e. South America, South Africa, Australia, and New Zealand.
