Type material.

Male holotype (EU052), from Nuevo Leon, Mexico, at La Huasteca Canyon, 3mi SW of Santa Catarina, 25.6544, -100.5075 4, 1114m, coll. L. Malarat 11.viii.1978; deposited in AMNH.

Etymology.

The specific epithet is a noun taken in apposition and is in reference to the type locality.

Diagnosis.

Male Eucteniza huasteca type specimen differs from all other Eucteniza species on the basis of its very small size, very pale yellow coloration, and by having a distinct patch of spines on the distal aspect of the palpal tibia (Figs 43, 44, 47); other species are typically larger in size, darker in coloration, and lack similar palpal tibia spination.
