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.


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


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