70 BULLETIN OF THE UNIVERSITYOF NEBRASKA STATE MUSEUM<br />
scissorial region with strong apical tooth,<br />
weak medial tooth; molar region with welldeveloped<br />
lamellae. Maxilla with 3 apical,<br />
cup-like teeth. Apex <strong>of</strong> mentum with triangular<br />
medial tooth curved into oral cavity. Antenna<br />
10-segmented; club slightly shorter<br />
than other segments combined, approximately<br />
equal to clypeal length. Pronotum:<br />
Surface glabrous, sparsely punctate, with<br />
moderate punctures. Marginal bead weak laterally,<br />
absent apically and basally. Elytron:<br />
Surface glabrous; longitudinal striae weakly<br />
punctate, punctures moderate with dark coloration;<br />
intervals sparsely punctate to<br />
impunctate. Suture with distinct apical spine<br />
(sometimes worn down). Pygidium: Width<br />
approximately 2.8 times length medially. Surface<br />
rugose, weakly convex, glabrous except<br />
near apex; setae short, tawny. Venter: Thorax<br />
sparsely setose, setae white. Mesothoracic<br />
process strongly produced, projecting anteriorly<br />
past protrochanter; apex rounded; shape<br />
conical-elongate, not flattened. Abdomen glabrous.<br />
Apical spiracles not extruding. Legs:<br />
Protibia with 3 teeth in apical half; 2 apical<br />
teeth subequal in size, third tooth weak.<br />
Mesotibia and metatibia widest medially.<br />
Protarsomeres 2-4 wider than long, cupshaped.<br />
Protarsomere 3-4 with internoapical<br />
stridulatory ridge. Protarsomere 5 without<br />
internal tooth. Mesotarsomere and metatarsomere<br />
5 with internobasal tooth. Unguitractor<br />
plate cylindrical, with 2 apical<br />
setae. Modified protarsal claw with length<br />
approximately equal to protarsomere 5, thickened<br />
and elongate when compared with other<br />
claw, dorsoventrally flattened, apex unevenly<br />
bifurcate. Modified mesotarsal and metatarsal<br />
claws elongated with ventral tooth, not<br />
thickened. Male Genitalia: Phallobase 1.1<br />
times longer than length <strong>of</strong> parameres.<br />
Parameres smooth, with strong lateral hook<br />
at apex (Fig. 19).<br />
Female (n=18). Length 23.0-28.7 mm,<br />
width 14.3-16.9 mm. As male except in the following<br />
respects. Head: Antennal club shorter<br />
than segments 2-7. Legs: Protarsomere 3-4<br />
without internoapical stridulatory ridge.<br />
Modified protarsal claw with ventral tooth,<br />
not thickened.<br />
DIAGNOSIS. This species is distinguished<br />
from all other species in the genus Platycoelia<br />
by the following combination <strong>of</strong> characters:<br />
frontoclypeal suture complete; apex <strong>of</strong> the<br />
clypeus not reflexed; labrum with a broad, triangular<br />
apical tooth strongly overlapping the<br />
mentum; mentum with a distinct tooth curved<br />
into the oral cavity; antenna 10-segmented;<br />
protibia dorsally without green coloration;<br />
elytron with the apex forming a weak nub or<br />
spine; elytron with yellow, longitudinal lines<br />
on interval 2 and base <strong>of</strong> striae 1; elytral apices<br />
not capable <strong>of</strong> completely covering the pygidium;<br />
metasternum and abdominal<br />
sternites uniformly green to yellow; mesothoracic<br />
process without strong green coloration;<br />
parameres with the apex rounded, expanded;<br />
parameres apicolaterally with a triangular<br />
hook and diagonal striae.<br />
