green with lighter striae. Additional characters
as follows. Male Genitalia: Phallobase 1.2
times longer than length of parameres. Parameres
dorsoventrally flattened, apicomedially
acute.
ETYMOLOGY. Platycoelia sandia named after
the watermelon-like appearance of this
species. Sandía is the Spanish word for watermelon.
DIAGNOSIS. This species is distinguished
from all other species in the genus Platycoelia
by the following combination of characters:
frontoclypeal suture complete; 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 mix of small and moderate
punctures; elytron with yellow to light
green, longitudinal lines on all striae; elytral
apices capable of completely covering pygidium;
pygidium entirely setose; metasternum
and abdominal sternites dark brown to
black; 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. 54). Occurs on the
eastern slope of the Andes Mountains in Ecuador.

TYPE SPECIMENS. Platycoelia penai Frey
holotype male at MGFT labeled a) “Ecuador,
Quito S.Domingo, 2400m Pena, II.1965”
(typeface), b) “TYPUS” (red label, typeface), c)
“Platycoelia penai n. sp. det.G.Frey,1966
Type” (handwritten and typeface). Eight female
paratypes with identical locality labels
and similar type labels are at MGFT (6) and
HAHC (2). Frey (1967) stated that there are
two males and seven females in the type series,
but there are one holotype male and
eight paratype females in the type series.
Type locality: Santo Domingo (suburb of
Quito), Pichincha, Ecuador.
DESCRIPTION. Male (n=4). Length 23.8-
25.9 mm, width 14.4-14.9 mm. Color lime
green to olive green (sometimes darkened to
brownish-green) with elytral intervals 3, 5, 7
slightly lighter green; narrow yellow elytron,
pronotum, scutellum margins; metasternum
medially with longitudinal black line. Body
ovate, strongly convex. Head: Dorsal surface
glabrous. Frons moderately punctate (base) to
rugopunctate (apex); clypeus rugopunctate,
punctures small or moderate. Frons not depressed.
Frontoclypeal suture complete.
Clypeal apex broadly rounded. Eyes separated
by approximately 3.5 transverse eyewidths.
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,
approximately equal to length of frons.
Pronotum: Surface glabrous, densely punctate,
with small or moderate punctures. Marginal
bead weak apicolaterally, laterally,
absent elsewhere. Elytron: Surface glabrous;
longitudinal striae weakly punctate, punc-
