Stenoterommata quena

Stenoterommata quena is a species of mygalomorph spiders of Argentina, named after its type locality: La Quena, Salta Province.[2] Females are recognized by the numerous (7 or more) spines on prolateral patella III. The rastellum is stronger, and the maxillae are shorter, than in other species of its genus. The presence of preening combs in metatarsi I is also unusual.
