MONOGRAPHIC REVISION OF PLATYCOELIA 103
with large, black, medial spot. Body ovate,
strongly convex. Head: Dorsal surface glabrous.
Frons densely punctate, clypeus
rugopunctate, punctures small or moderate.
Frons not depressed. Frontoclypeal suture incomplete,
absent medially. Clypeal apex
broadly rounded. Eyes separated by approximately
2.7 transverse eye-widths. Labrum
sparsely punctate, with moderately large, setose
punctures, setae tawny. Apex of labrum
with triangular, medial tooth; apex of tooth
broadly truncate, extending past apex of mentum.
Apex of mentum with triangular medial
tooth curved into oral cavity. Antenna 10-segmented;
club slightly less than other segments
combined, slightly longer than clypeal
length. Pronotum: Surface glabrous, densely
punctate, with small or moderate punctures.
Marginal bead weak apicolaterally, laterally,
absent elsewhere. Elytron: Surface glabrous;
longitudinal striae weakly punctate, punctures
moderate with dark coloration; intervals
densely punctate, punctures small. Suture
angled apically, without spine. Pygidium:
Width approximately 2.4 times length medially.
Surface weakly convex, moderately punctate;
punctures small or moderate, setose;
setae cream colored. Venter: Thorax densely
setose (except glabrous medially), setae white.
Mesothoracic process strongly produced, projecting
anteriorly to protrochanter; shape
conical-elongate, apex rounded; ventrally flattened.
Abdomen sparsely setose, setae white.
Apical spiracles not extruding. Legs: Protibia
with 2 teeth in apical quarter. Mesotibia and
metatibia widest medially. Protarsomeres 2-4
wider than long, cup-shaped. Protarsomere
3-4 with internoapical stridulatory ridge.
Protarsomere 5 with internobasal stridulatory
ridge. Mesotarsomere and metatarsomere
5 with internobasal tooth. Unguitractor plate
cylindrical, with 2 apical setae. Modified
protarsal claw with length greater than
protarsomere 5, thickened and elongate
when compared with other claw, laterally
flattened, apex unevenly bifurcate. Modified
mesotarsal and metatarsal claws elongated
with ventral tooth, not thickened.
ALLOTYPE. Female: length 29.3 mm, width
16.9 mm. As male except in the following respects.
Color of abdominal sternites brown.
Head: Antennal club slightly greater than
segments 2-7. Legs: Protibia with 3 teeth in
apical half, third tooth shorter. Protarsomere
3-4 without internoapical stridulatory ridge.
Protarsomere 5 without internal tooth. Modified
protarsal claw with ventral tooth, not
thickened.
VARIATION. Male (n=10). Length 26.5-29.7
mm, width 15.7-17.2 mm. Female (n=7).
Length 28.0-31.6 mm, width 17.5-18.5 mm.
Paratypes similar to holotype and allotype
except in the following respects. Color of body
sometimes darkened to dark green or brownish-green,
abdominal sternites green to dark
brown. Additional characters as follows. Male
Genitalia: Phallobase 1.2 times longer than
length of parameres. Parameres dorsoventrally
flattened, apicomedially acute.
ETYMOLOGY. The specific epithet of Platycoelia
convexa refers to the general shape of
the body.
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 uniformally
green; elytral apices capable of completely
covering the pygidium; pygidium entirely setose;
metasternum with a dark, medial patch;
protibial spur noticeably shorter than the adjacent
tibial apex; 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. 52). Known from the
Andes Mountains from central Perú to central
Bolivia.
