Type species.

Malleusocoris minimus Dellapé & Melo, sp. nov.

Diagnosis.

Small. Antenna capitate, basiflagellomere shortest, distiflagellomere conspicuously enlarged; forefemur with a single inner row of spines.

Description.

Body length less than 3.5 mm. Dorsum shiny. Antenna capitate, basiflagellomere shorter than scape, distiflagellomere conspicuously enlarged. Juga rounded. Eyes relatively small, not surpassing dorsal margin of head in lateral view; vertex rounded; postocular region of head shorter than interocellar distance. Ocelli closer to posterior margin of head than to eyes, located before an imaginary line passing across the posterior border of eyes. Ventral surface of head with a median groove; buccular juncture U-shaped, placed in a groove close to labial insertion. Pronotum coarsely punctate, punctures larger on posterior pronotal lobe. Lateral margins of anterior pronotal lobe rounded; lateral margins of posterior lobe carinate, carina broader on posterior half; a distinct anterior collar present but not demarked posteriorly by a linelike groove. Claval punctures arranged in three regular rows. Mesepimeron enclosed. Evaporative area reduced. Forecoxa with a small spine. Forefemur with a few tiny spines restricted to inner row; male foretibia mutic. Posterior margin of dorsal aperture of pygophore broadly rounded. Aedeagus unspined.

Etymology.

The genus name is the combination of the Latin malleus (= hammer or mallet) by the incrassate distiflagellomere, and the Greek koris (= bug). The gender is masculine.
