mm. Paratypes similar to holotype and allotype
except in the following respects. Color of
body sometimes darkened to dark green or
brownish-green. Additional characters as follows.
Male Genitalia: Phallobase 1.7 times
longer than length of parameres. Parameres
dorsoventrally flattened, apicomedially acute.
ETYMOLOGY. Platycoelia grandicula is derived
from Latin meaning “the rather large
Platycoelia.”
DIAGNOSIS. This species is distinguished
from all other species in the genus Platycoelia
by the following combination of characters:
frontoclypeal suture incomplete; labrum with
a well-developed, truncate apical tooth
strongly overlapping the mentum; mentum
with a distinct tooth curved into the oral cavity;
antenna 10-segmented; pronotum surface
densely punctate with a mix of small and
moderate punctures; elytron with a distinct,
yellow, longitudinal line on stria 1; elytral api-
ces capable of completely covering the pygidium;
pygidium entirely setose; metasternum
and abdominal sternites green or yellow;
protibial apical 2 teeth adjacent, located in
the apical quarter of the protibia; protibial
spur noticeably shorter than the adjacent
tibial apex; protarsomere 3 in males without
a distinct apical stridulatory patch; modified
protarsal claw in males laterally flattened;
mesotarsomere 4 and metatarsomere 4 in
males with an apical stridulatory ridge;
mesotarsomere 5 and metatarsomere 5 with
an internobasal tooth; parameres with the
apex dorsoventrally flattened.
DISTRIBUTION (Fig. 62). Occurs in mid- to
low-elevation montane areas of Costa Rica
and Panamá.
