Diagnosis: Labium apex surpasses metacoxae; two well-defined rows of punctures parallel to clavo-corial suture on the corium Corium; Laterotegites IX attaining sternum VII.

Redescription. Total length: 10.9–11.1 mm.

Head: Flattened dorsally, surface shining, with faint, radiating rugae and minute, widely scattered punctures; clypeus shorter than mandibular plates, apex narrower than the base; interocular length greater than the length of the head ( Fig. 17B ); labium surpassing posterior coxae, sometimes reaching to sternite IV, labial segment II without semicircular foliaceous lobe ( Fig. 17D ).

Thorax: Pronotum surface with very scattered coarse punctures, disc impunctate; lateral margin with submarginal row of twelve setigerous punctures; transverse impression weak, marked by a very irregular interrupted row of punctures; anterior lobe with intermixed coarse and fine punctures laterally and in subapical band paralleling anterior margin; posterior lobe with few minutes and fewer scattered coarse punctures ( Fig. 17A ). Propleuron polished, with few small punctures in depression ( Fig. 17D ). Scutellum disc polished, with about half dozen coarse punctures and several fine ones widely scattered. Hemelytron shining; clavus with single row of coarse punctures and several finer scattered ones ( Fig. 17A ); mesocorium with one complete and one partial row of punctures paralleling claval suture; exocorium less densely punctured than mesocorium; costa with four to six setigerous punctures. Mesopleural evaporatorium with pseudoperitreme ( Fig. 17C ); anterolateral area with few oblique rugae. Posterolateral and posterior areas impunctate. Metatibia distinctly compressed.

Abdomen: Sternites III to VI polished, without rows of setigerous punctures across segments ( Fig. 17D ).

Type data: Type specimen deposited in the British Museum, labeled with the locality “Columbia”, based on its distribution; the type locality should be Colombia.

Distribution: Mexico, Guatemala, Colombia, Brazil, Ecuador —( Fig. 15 ).

Remarks: See remarks to C. teter .
