Stenoterommata palmar is a mygalomorph spider of Argentina, named after its type locality: Parque Nacional El Palmar, Entre Rios.[2] 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.

- Female: total length 15.05 millimetres (0.593 in); cephalothorax length 5.95 millimetres (0.234 in), width 4.6 millimetres (0.18 in); cephalic region length 0.38 millimetres (0.015 in), width 3.25 millimetres (0.128 in); fovea width 0.67 millimetres (0.026 in); labium length 0.52 millimetres (0.020 in), width 1.06 millimetres (0.042 in); sternum length 3.2 millimetres (0.13 in), width 2.62 millimetres (0.103 in). Its cephalic region is convex, with its fovea slightly procurved. Its labium possesses 1 cuspule, and has no serrula. Its sternum is reborded and with small, marginal and oval sternal sigilla (similar to S. tenuistyla). Chelicerae: rastellum formed by attenuate setae. Color as in the male.[2]
