( Fig. 39, 40 , 45 )

Peridinetus sp. 10. Marquis (1990: 107, 1991: 181).

Diagnosis. See under diagnosis of 15. Peridinetus laetus . Small or partially abraded male P. pena are very difficult to distinguish from P. l a e t u s.

Description. Total length 3.3–4.6 mm, standard length 3.2–4.4 mm, width 1.7–2.3 mm. Integument black, head, rostrum and legs reddish to dark brown, antenna red; color pattern formed by red, olive green, white and small dark setae, basal half of elytra with conspicuous semicircular black area, anterior half of pronotum red ( Fig. 39 ), elytral flank with semicircular dark area with white, in lateral view usually vertical spot above ventrites 1 and 2 ( Fig. 40 ), interstria 5 often with white spot in front of ridge. Frons shallowly depressed (male) or convex (female). Rostrum 0.89–1.02 × length of pronotum, antenna inserted slightly anterior of (male) or at middle (female); female with dorsal groove basally (ca. half diameter of rostrum; Fig. 45 ) of antennal insertion. Pronotum 0.88–0.98 × longer than wide, sides subparallel in basal half, with lateral tumidity and raised setae giving angular outline in dorsal view, front tubulate; disk arched, microreticulate, impunctate. Prosternum with plumose setae. Elytra 1.33–1.39 × longer than wide, humeri 1.44–1.60 × wider than pronotum, subtriangular, sides gradually converging in basal two thirds; striae distinct, interstriae 3 and 5 ridged in distal third, 7 throughout with median depression, 9 with ridge fading toward front, preapical callus moderate; tarsal claws subconnate.

Distribution. This species has been found in Nicaragua, Costa Rica and western Panama.

Plant association. Peridinetus arieianum (Marquis 3 ×), P. bisasperatum (Marquis 3 ×), P. colonense (Marquis 3 ×), P. phytolaccaefolium (Marquis 1 ×), P. reticulatum (Marquis 1 ×), P. sancti-felicis s. l. (Marquis 7 ×), P. silvivagum (Marquis 1 ×).

Specific epithet. The name is a noun in apposition.

Note. Peridinetus pena was treated by Marquis (1990, 1991) as morphospecies 10, P. l a e t u s as morphospecies 9. Whitehead, who made this distinction for the specimens collected at La Selva, did not reveal the underlying criteria in his letters and notes (Systematic Entomology Lab, unpublished).
