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 />

DISTRIBUTION (Fig. 48). Northwestern<br />
