stenoterommata palmar is a mygalomorph spider of argentina, named after its type locality: parque nacional el palmar, entre rios. 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".
