Identification
Distinguished from and similar rhyparochromid seed bugs by the presence of an oblique transverse band across the body. The combination of this banding pattern with the dull, dirt-colored body separates it from more vividly marked lygaeoid . Examination of genitalia may be required for definitive identification from closely related Pseudopachybrachius .
