TYPE SPECIES: Leioproctus (Leioproctus) capito Houston, 1990 .

DIAGNOSIS: This subgenus differs from the nominate subgenus of Eremocolletes by the inner orbits of the compound eyes diverging below, the maxillary palpus only 0.5× as long as the post-palpal portion of the galea, the mandible of the male with the upper margin excavated subapically, and the males conspicuously larger than females.

ETYMOLOGY: The new subgeneric name is a combination of Houston, surname of Terry F. Houston who first recognized this group and to honor his masterful work on Australian bees, and the Latin suffix – ellus, denoting a diminutive. The gender of the name is feminine.
