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).
