Description:

Total length 4.7-6.3 mm, standard length 4.4-6.1 mm, width 2.4-3.2 mm; integument reddish brown, tarsi fuscous, yellow scales condensed in dorsolateral pronotal vitta and in variously developed subapical elytral fascia; white scales condensed in lateral fascia between metasternum and outer interstriae ( Fig. 1-2 ), specimens from low elevations with color pattern reduced; pronotal disk slightly arched, punctures confluent, intervals granular, confluent in midline; scutellum square, apex round to acuminate; elytra subtriangular, conjointly rounded and completely covering pygidium, interstriae costate except for flat portions of disk; ventral tooth variously reduced on profemur, largest on mesofemur; tibiae with praemucro indistinct, male with sparse fringe of long hairs on ventral edge of protibia; claws subconnate at base; male genitalia and associated structures as in Fig. 7-13 , flagellum approximately 3× longer than body of aedeagus, basal portion recurved and with subdistal sclerite ( Fig. 10 ), internal sac with slight microsculpture but without denticles.

Plant association:

I collected six adult weevils from young (sterile) specimens of two unidentified plant species possibly belonging to Psychotria . The larva makes galleries in the apical portion of the main stem, thereby inhibiting further terminal growth.

Distribution:

The species is known from six localities in premontane and montane habitats (600-2100 m) in Costa Rica and Panama.

Epithet:

A Latin present participle composed of ater (black or dark) and rubens (turning red).
