gins. Ventrally with dark brown metasternum
and abdominal sternites. 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
3.4 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 approximately equal to other
segments combined, slightly shorter than
length of frons. Pronotum: Surface glabrous,
densely punctate, with small or moderate
punctures. Marginal bead weak apicolaterally,
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 2.6 times
length medially. Surface weakly convex,
densely punctate; punctures small or moderate,
setose; setae short, cream colored. Venter:
Thorax densely setose (except glabrous medially),
setae white. Mesothoracic process
strongly produced, projecting anteriorly past
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 tooth.
Mesotarsomere and metatarsomere 5 with
internobasal tooth or swelling. 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. Male Genitalia:
Phallobase 1.5 times longer than length of

parameres. Parameres dorsoventrally flattened,
apicomedially acute.
ALLOTYPE. Female: length 26.1 mm, width
14.8 mm. As male except in the following respects.
Head: Antennal club approximately
equal to 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=40). Length 23.7-26.7
mm, width 13.8-16.0 mm. Female (n=18).
Length 28.2-31.4 mm, width 16.2-17.9 mm.
Paratypes similar to holotype and allotype
except in the following respects. Color of body
sometimes dark green or brownish-green.
Ventrally with black to reddish-brown metasternum
and abdominal sternites (sometimes
green along lateral edge).
ETYMOLOGY. Platycoelia galerana is
named after the Cordillera Galeras, the region
of the eastern Andes Mountains where
much of the type series was collected.
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, club length
greater than other segments combined;
pronotum surface densely punctate with a
mix of small and moderate punctures; scutellum
disc usually green; elytron with well-defined,
yellow, longitudinal lines on striae 3
and 5; elytral apices capable of completely
covering the pygidium; pygidium entirely setose;
metasternum black (at least medially);
abdominal sternites dark; 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.
