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).
