Abstract

Three new species of Iulidesmus Silvestri, 1895 (Diplopoda: Polydesmida: Paradoxosomatidae), one of the most species-rich genera of Diplopoda globally that currently encompasses about 90 species, are described from the Andes: I. inga Golovatch, Romero-Rincon, Akkari and Alvear, new species, from Colombia. I. bilobus Golovatch, Romero-Rincon, Akkari and Alvear, new species, from Ecuador, and I. zakharovi Golovatch, Romero-Rincon, Akkari and Alvear, new species, from Peru. The following new combination is proposed: Iulidesmus alagoanus (Schubart, 1950), from Brazil, new combination, ex Habrodesmus Cook, 1896. The female holotypes of Strongylosoma glabrum Peters, 1865, from Colombia, and Strongylosoma vermiculare Peters, 1865, from Venezuela, are revised and illustrated for the first time, both being tentatively assigned to Iulidesmus and presently referred to as I. glabrus (Peters, 1865) and I. vermicularis (Peters, 1865), new combinations, ex Strongylosoma Brandt, 1833. The male paratype of Iulidesmus jeekeli Romero-Rincon and Golovatch, 2024, a previously misidentified species from Colombia, is likewise revised, illustrated, and shown to be conspecific with the holotype.

Resumen

Tres nuevas especies de Iulidesmus Silvestri, 1895 (Diplopoda: Polydesmida: Paradoxosomatidae), uno de los géneros más diversos de Diplopoda a nivel mundial que actualmente incluye cerca de 90 especies, son descritas para los Andes: I. inga Golovatch, Romero-Rincon, Akkari and Alvear, nueva especie, para Colombia. I. bilobus Golovatch, Romero-Rincon, Akkari and Alvear, nueva especie, para Ecuador, e I. zakharovi Golovatch, Romero-Rincon, Akkari and Alvear, nueva especie, para Perú. Se propone la siguiente nueva combinación: Iulidesmus alagoanus (Schubart, 1950), de Brasil, nueva combinación, ex Habrodesmus Cook, 1896. Los holotipos hembras de Strongylosoma glabrum Peters, 1865, para Colombia, y Strongylosoma vermiculare Peters, 1865, para Venezuela, son revisados e ilustrados por primera vez, ambos tentativamente asignados a Iulidesmus y actualmente referidos como I. glabrus (Peters, 1865) e I. vermicularis (Peters, 1865), nuevas combinaciónes, ex Strongylosoma Brandt, 1833. El paratipo macho de Iulidesmus jeekeli Romero- Rincon y Golovatch, 2024, una especie de Colombia previamente identificada erróneamente, también se revisa, ilustra y muestra que es conespecífica del holotipo.
