( Fig. 2, 3 , 33, 34 , 43 )

Peridinetus sp. 3. Marquis (1990: 107, 1991: 181).

Diagnosis. Peridinetus wyandoti is one of several species with red anterior, black median and olive posterior portions. Of diagnostic value for this relatively small species are the white spot above the metepisternum ( Fig. 34 ) and the Mohawk-style frontal crest of the female.

Description. Total length 2.7–4.4 mm, standard length 2.6–4.2 mm, width 1.2–2.0 mm. Integument dark reddish brown to black, rostrum, legs and often apical portion of elytron reddish to dark brown; color pattern formed by red, olive green, white and small dark setae, with basal half of elytra with conspicuous semicircular black area and anterior half of pronotum red ( Fig. 33 ), elytral flank with conspicuous white spot above metepisternum ( Fig. 34 ). Frons with shallow fovea (male) or crest of stiff setae (female; Fig. 43 ). Rostrum 0.84–1.15 × length of pronotum, antenna inserted at mid-length of rostrum (male) or slightly more basally (female). Pronotum 0.82–0.95 × longer than wide (with considerable variation in size), sides curved in basal half, constricted and tubulate in front; disk punctate, median line impunctate and often raised. Prosternum with plumose setae. Elytra 1.50–1.64 × longer than wide, humeri 1.33–1.69 × wider than pronotum, sides gradually converging in basal half; striae distinct, odd-numbered interstriae ridged at least apically (7 and 9 complete or nearly so), preapical callus inconspicuous; tarsal claws subconnate.

Distribution. This species is known from southern Nicaragua, Costa Rica, western Panama and the Pacific side of Ecuador.
