Diagnosis: Second antennal segment shorter than third, labium between or slightly beyond posterior coxae; surface of the scutellum disc impunctate or with few widely scattered punctures; Gonocoxites VIII almost as long as broad.
Redescription. Total length: 10.4–11.6 mm.
Head flattened, anterior outline a semicircle, clypeus nearly as long as mandibular plates; interocular width less than length of head; surface shining, with moderate, radiating rugae, punctation fine or absent (Fig. 14B); labium reaching between or slightly beyond posterior coxae, labial segment II without semicircular foliaceous lobe (Fig. 14D).
Thorax: Lateral margin of the pronotum with 16 to 18 setigerous punctures submarginally; transverse impression weak, more strongly impressed laterally than medially, marked with irregular, medially interrupted row of coarse punctures; anterior lobe impunctate except for few punctures laterally and irregular, transverse row of coarse punctures subapically; posterior lobe polished, with few widely scattered punctures (Fig. 14A). Scutellum disc impunctate or with few widely scattered punctures. Hemelytron polished; clavus with one complete row of punctures; mesocorium with two rows of punctures paralleling claval suture, elsewhere closely punctate; exocorium with punctation much sparser than on mesocorium; costa with five to seven setigerous punctures (Fig. 14A). Mesopleural evaporatorium with pseudoperitreme; posterolateral area impunctate (Fig. 14C). Metatibia distinctly compressed, not expanding toward apex (Fig. 14D).
Abdomen: Sternites III to VI polished, without rows of setigerous punctures across segments (Fig. 14D).
Type data: The holotype specimen has not clear location, but the locality is reported from Brazil. The type specimen of Cyrtomenus excavatus previously synonymized and deposited in the British Museum is from Costa Rica.
Distribution: Guatemala, Costa Rica, Panama, Colombia First record, Ecuador, Brazil, Argentina First record— (Fig. 11).
Remarks: Morphological similarities with C. grossus could sometimes lead to misidentification, but the interocular length is the best feature to separate these two species.
