Diagnosis. Peridinetus costatus and P. odone differ from all known congeners by noticeably ridged elytral interstriae, which are raised on the mid-sections of interstriae 3 and 5. Peridinetus costatus has a distinct subapical elytral fascia of yellow setae ( Fig. 25 ) and dorsolateral vittae on the pronotum, which are inconspicuous in P. odone ( Fig. 28 ). The four studied specimens were 3.4–4.2 mm long (standard length 3.3– 4.0 mm).

Distribution. This species has been found in southern Mexico and Guatemala.

Plant association. Unknown.

Type material. 2 syntypes, Mexico [without site] ( BMNH 1) and Guatemala, Zapote ( BMNH 1).

Material examined. Mexico. Veracruz: Los Tuxtlas Biol. Station ( CMNC 2, JPPC 1). Guatemala. Izabal: 8 km N Las Escobas, 800 m ( CMNC 1). Total 4 specimens.
