25. Peridinetus opacus Champion View in CoL

( Fig. 62, 63 View FIGURES 58 – 65 )

Peridinetus opacus Champion, 1907: 178 View in CoL . Seidlitz (1909: 326), Hustache (1938: 9), Blackwelder (1947: 887), O’Brien & Wibmer (1982: 178).

Diagnosis. Peridinetus opacus is a small, inconspicuous weevil with few setae ( Fig. 62 View FIGURES 58 – 65 ), which is very similar to P. frontalis ( Fig. 60 View FIGURES 58 – 65 ). Champion apparently was unaware of P. frontalis when he described P. opacus from Panama. The Middle American material now available suggests that P. opacus occurs at mid-elevations in the Cordilleras Central and Talamanca, while typical P. frontalis occur in the adjacent lowlands. The chief distinguishing character of P. opacus is the laterally angular pronotum. These two taxa belong to a predominantly South American species complex and their taxonomic ranks need to be readdressed in a future investigation of that fauna. The studied specimens were 3.1–4.5 mm long (standard length 2.9–4.3 mm).

Distribution. This species has been found at mid-elevations in Costa Rica and Panama.

Plant association. Piper hispidum complex (Prena 11 ×)
