Diagnosis. Peridinetus canus has a distinctive, uniformly grey color pattern with dark marks on the apical part of the elytron ( Fig. 17 ) and cannot be confused with any other species. The studied specimens were 6.4– 9.7 mm long (standard length 6.0–9.0 mm).

Distribution. This species occurs on the Pacific side of Cordillera de Talamanca in Costa Rica and Panama.

Note. Casey (1922) was mincing Champion’s (1907) words when he described one syntype of P. canus (a homogeneous series from two sites in Chiriquí) as Conophora cana dispersa . The available records show that this is a single, well-defined species that is restricted to the Pacific side of the Cordillera de Talamanca. Conophora cana dispersa is a new subjective synonym of P. canus .
