MONOGRAPHIC REVISION OF PLATYCOELIA 167
moderately to densely punctate, punctures
moderate. Frons slightly depressed
medioapically. Frontoclypeal suture weakly
bisinuate. Clypeus rectangular, apex reflexed.
Eyes separated by approximately 5.5 transverse
eye-widths. Labrum sparsely punctate,
with moderately large, setose punctures, setae
tawny. Apex of labrum with minute, triangular,
medial tooth, apex of tooth well
separated from apex of mentum. Mandibular
scissorial region with 2 teeth, molar region
smooth. Maxilla with 4 apical teeth. Apex of
mentum with medial notch (Fig. 4). Antenna
9-segmented or 10-segmented (segments 5
and 6 often fused); club slightly shorter than
other segments combined, approximately
equal to length of frons. Pronotum: Surface
glabrous, sparsely punctate, with small and
moderate punctures. Marginal bead present
apically and laterally, absent basally. Elytron:
Surface glabrous; longitudinal striae impressed,
impunctate to weakly punctate; intervals
impunctate. Suture apically rounded.
Pygidium: Width approximately 1.8 times
length medially. Surface smooth, weakly convex,
impunctate (except sparsely punctate
near apex); punctures moderate, glabrous (except
near apex); setae long, tawny. Venter:
Thorax densely setose; setae long, tawny to
golden-brown. Mesothoracic process barely
produced, projecting anteriorly to subapex of
mesocoxa (Fig. 10). Abdomen sparsely setose;
setae moderately-sized, tawny to goldenbrown.
Apical spiracles weakly extruding.
Legs: Protibia with 3 teeth in apical half; first
and second teeth subequal in size; third tooth
small, often worn and obsolete, removed
slightly from apical teeth. Mesotibia and
metatibia widest between base and middle.
Protarsomeres 2-4 wider than long, cupshaped.
Protarsomere 4 with internoapical
stridulatory ridge. Protarsomere 5 with
internomedial stridulatory tooth. Mesotarsomere
5 and metatarsomere 5 without internal
tooth. Unguitractor plate cylindrical, with
1 apical and 1 subapical seta. Modified
protarsal claw with length approximately
equal to protarsomere 5, thickened and elongated
when compared with other claw, dorsoventrally
flattened, apex unevenly bifurcate.
Modified mesotarsal and metatarsal claws
elongated with ventral tooth, not thickened.
Male Genitalia: Phallobase 1.3 times longer
than length of parameres. Parameres with
apex ventrally angled.
Female (n=5). Length 17.5-17.7 mm,
width 9.8-10.0 mm. As male except in the following
respects. Head: Antennal club approximately
equal to segments 2-7 (2-6 in
9-segmented individuals). Legs: Protibia with
third tooth distinct, subequal in size to other
teeth. Protarsomere 4 without internoapical
stridulatory ridge. Protarsomere 5 without internal
tooth or swelling. Modified protarsal
claw with ventral tooth, not thickened.
DIAGNOSIS. This species is distinguished
from all other species in the genus Platycoelia
by the following combination of characters:
frons dark in color (relative to rest of dorsal
surface), medioapically depressed; frontoclypeal
suture complete; apex of the labrum
with a reduced, triangular tooth not overlapping
the mentum; mentum with a medial
notch; pronotum with dark maculations;
elytron without distinct, yellow, longitudinal
lines; elytral apices not capable of completely
covering the pygidium; apex of the elytral suture
without an acute spine; mesothoracic
process nub to weakly projecting apically; apical
abdominal spiracle weakly protuberant;
mesotarsomere 5 and metatarsomere 5 without
an internal tooth; parameres with the
apex rounded, not expanded.

arm of the Andes Mountains to southern
