( Fig. 13, 14 )

Peridinetus rugipes . Faust [manuscript name]. Peridinetus sp. 7. Marquis (1991: 181).

Diagnosis. Because of the relatively wide pronotum and slightly protruding humeri, P. notabilis has a conspicuous ovate shape ( Fig. 13 ) that is shared in the study area only by P. p i c t u s ( Fig. 15 ). The yellow elytral mark is separated in the middle and transverse, but continuous and subspherical in P. pictus .

Description. Total length 4.8–6.1 mm, standard length 4.6–5.8 mm. Integument black; vestiture of elongate setae dense, yellow in large macula on pronotal flank and in elytral fascia, black elsewhere ( Fig. 13 ). Rostrum 0.93–1.10 × length of pronotum, anteantennal portion 0.45–0.50 (male) and 0.49–0.55 × (female) length of rostrum. Pronotum 0.71–0.74 × longer than wide, greatest width near base, then gradually rounded and tubulate in front; disk finely punctate, indistinctly costate. Elytra 1.39–1.43 × longer than wide, humeri 1.18–1.25 × wider than pronotum, sides curved gently; striae subtle, interstriae not ridged, preapical callus inconspicuous; tarsal claws subconnate, male protarsi laterally with long setae.

Distribution. This species has been found on the Caribbean side of the Cordillera Central in Costa Rica.

Plant association. Piper arboreum (Marquis 1 ×), P. a u r i t u m (Marquis 1 ×), P. biseriatum (Marquis 3 ×), P. cenocladum (Marquis 9 ×, Prena 2 ×), P. imperiale (Marquis 1 ×, Prena 3), P. melanocladum (Marquis 1).
