The millipede genus Iulidesmus Silvestri, 1895 in Colombia (Polydesmida, Paradoxosomatidae, Catharosomatini)

The paradoxosomatid genus Iulidesmus Silvestri, 1895 in the fauna of Colombia is shown to presently contain nine species. Three of them are still obscure, two of which could be revised based on type (I. alacer (Attems, 1944)) or new material (Orthomorpha proxima Silvestri, 1898), one is a nomen dubium (Strongylosoma glabrum Peters, 1864), while further six are described as new here: Iulidesmus garciae n. sp., I. minerus n. sp., I. florezi n. sp., I. sabaneta n. sp., I. icni n. sp., and I. jeekeli n. sp. A key to all six new species of the genus and their distribution map are provided.
