Abstract Malacostracan crustaceans are very diverse today, but their evolutionary history and biodiversity during the Paleozoic remain understudied. One clade within Malacostraca is Belotelsonidea, crustaceans with a shrimp-like body plan only known from the Carboniferous. We describe the fourth species of this group, Lobetelson feldmanni n. sp., from the Pennsylvanian (Kasimovian) of the Kinney Brick Quarry, New Mexico, USA. The holotype is a flattened, relatively complete specimen with an eye preserved. A second, less well-preserved specimen from the same locality might be referable to the new species. This record represents the youngest record of Belotelsonidea, now ranging from the upper Tournaisian to the Kasimovian, equivalent to ca. 40 Myr. Paleobiogeographically, belotelsonids are only known from Scotland and various parts of the USA thus far, located near the equator to ~20° south during the Carboniferous. Whereas most belotelsonids are thought to have lived in a marine environment, some of the oldest specimens from Scotland are interpreted to have inhabited areas with limited to no marine influence.
