Ectinopus muticus Froeschner

Diagnosis. Either the short, third antennal segment or the oblique, crenulate impressed line extending laterally from apex of the peritreme sets this species apart.

Head. Anterior outline subquadrate; surface impunctate, with a few moderate oblique rugae. Pronotum with transverse impression with several widely separated punctures, in a broad irregular band; rest of surface virtually impunctate except for about a dozen punctures laterally on anterior lobe. Scutellum surface with several distinct, well-separated moderate punctures; apex impunctate.
