Description:
Total length
3.7-5.1 mm
, standard length
3.6-4.8 mm
, width
1.8-2.7 mm
; integument brown, appendages reddish brown, yellow scales condensed in dorsolateral pronotal vitta and in variously developed fascia arching from metasternum across elytral callosity to apex (
Fig. 3-4
), fragmented in Panamanian specimens; 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; pro- and mesotibiae with praemucro distinct, male with sparse fringe of long hairs on ventral edge of protibia; claws separate at base; male genitalia similar to those of
F. atrorubens
, apex of aedeagus with sides less converging, basal portion of flagellum more narrowly curved, internal sac denticulate.
Plant association:
I collected the
holotype
and
one paratype
from foliage of
Psychotria chitariana
DWYER & HAMMEL
(identification confirmed by B. HAMMEL).
Distribution:
The species has been collected at three localities, one in
Costa Rica
(Atlantic side) and two in
Panama
, between
300-820 m
elevation.
Epithet:
A modified perfect participle derived from Latin
pingo
, meaning fairly colored.
Note:
The specimens from the three collecting sites show considerable variation in the color pattern; only the two Costa Rican specimens possess completely developed fasciae. Because the only male in the series is atypically small, I selected a fully developed female as
holotype
.
