Etymology
For La Mar, the province of Ayacucho where the types were collected. Kaderka does not state the derivation. The catalogue carries the name as lamarense rather than the published lamarensis, correcting the adjective ending to agree with the neuter gender of Urupelma.

Taxonomic History
- 2026 Urupelma lamarensis Kaderka, 2026 - described from a male holotype, a male paratype and a female paratype taken at Moyabamba in the La Mar province of Ayacucho, Peru, on 31 August 2022. The material had been sitting in the arachnid collection of the Museo de Historia Natural in Lima, where Kaderka found it during a visit in 2025; in the same paper's list of examined material it still appears under the provisional name "Urupelma sp.".
- The World Spider Catalog carries the species as Urupelma lamarense. The epithet is an adjective and Urupelma is neuter, so the published -ensis ending is corrected to -ense for gender agreement. The name used here follows the catalogue; the paper, and the ZooBank act registered for it, both read lamarensis.
- The description is registered in ZooBank as act urn:lsid:zoobank.org:act:2CD0EA99-B2E0-42AE-999B-09B16A84CB27.
