Diagnosis. Peridinetus distinctus is recognizable by the presence of a single, oblique elytral fascia ( Fig. 23 ). It may be confused with P. cretaceus ( Fig. 21 ), Embates championi (Casey) , E. cretifer (Champion) and Pardisomus biplagiatus (Desbrochers) , all superficially similar but with two differently arranged fasciae (see note under P. cretaceus ). The studied specimens were 6.6–9.0 mm long (standard length 6.1–8.6 mm).

Distribution. This species occurs in southern Mexico, Guatemala, Belize and Honduras. Two specimens in historic collections are [erroneously?] labeled as being from Costa Rica and Brazil.

Plant association. Unknown.

Type material. 2 syntypes, Mexico [without site] ( BMNH 2).
