Stenoterommata palmar is a mygalomorph spider of Argentina, named after its type locality: Parque Nacional El Palmar, Entre Rios.Goloboff, Pablo A. "A revision of the South American spiders of the family Nemesiidae (Araneae, Mygalomorphae). Part 1, Species from Peru, Chile, Argentina, and Uruguay. Bulletin of the AMNH; no. 224." (1995). Females differ from other three-clawed Stenoterommata in the spermathecae having one triangular dome with a single receptaculum arising from its base; males are most similar to those of S. tenuistyla, but lack short ventral spines on the metatarsus I (typical of that species), and have a long, curved spine on the apical third of their ventral tibia I. Its burrowing behaviour is similar to that of S. tenuistyla.
