Diagnosis: Apices of the mandibular plates longer than clypeus forming triangular projections; lateral surface of the eyes without setae.
Redescription. Total length: 10.8–13.3 mm.
Head: Flattened dorsally, surface polished; mandibular plates with radiating rugae and punctures, submarginal row of setigerous punctures, apices forming blunt to acute triangles towards front, clypeus shorter than mandibular plates, apex strongly narrowed (Fig. 16B); labium reaching mesocoxae, labial segment II without semicircular foliaceous lobe (Fig. 16D).
Thorax: Pronotum with scattered coarse punctures on the anterior submargin, lateral surfaces, and posterior half; lateral submarginal row of six to nine setigerous punctures; transverse impression weak, marked by irregular, interrupted row of punctures (Fig. 16A). Propleuron polished, with numerous fine punctures in depression. Scutellum impunctate across base and apex, disc with widely scattered, coarse punctures. Hemelytron: Clavus and corium polished; clavus with single row of large punctures; mesocorial punctures forming two more or less distinct rows paralleling claval suture, elsewhere with scattered punctures; exocorium densely punctate; costa with 0–3 setigerous punctures (Fig. 16A, D). Mesopleural evaporatorium with pseudoperitreme; posterolateral area impunctate. Metatibia curved and compressed but not expanded near apex (Fig. 16D).
Abdomen: Sternites III to VI polished, without rows of setigerous punctures across segments (Fig. 16D).
Type data: The type specimen is lost, original description indicate that the type locality is Mexico.
Distribution: Mexico, Guatemala, Honduras, Costa Rica, Colombia First record, French Guiana, Brazil, Peru, Argentina —(Fig. 15).
Remarks: One of the biggest representatives of Cyrtomenus and easily recognizable by the projection of the mandibular plates, its biology, and ecology remain unknown.
