MONOGRAPHIC REVISION OF PLATYCOELIA 185<br />

DESCRIPTION. Male (n=4). Length 13.1-<br />

15.0 mm, width 8.1-9.3 mm. Color dorsally<br />

green; broad black band along apex and base<br />

<strong>of</strong> head; black band along lateral, apical and<br />

suture margins <strong>of</strong> elytron. Ventrally dark<br />

brown, dark yellow legs. Body ovate, convex.<br />

Head: Dorsal surface setose; setae long,<br />

tawny. Frons sparsely punctate (base) to<br />

densely punctate (apex), clypeus rugose,<br />

punctures moderate. Frons not depressed.<br />

Frontoclypeal suture complete, obscured by<br />

punctures. Clypeal apex rounded, reflexed.<br />

Eyes separated by approximately 4.8 transverse<br />

eye-widths. Labrum rugose, setose; setae<br />

tawny. Apex <strong>of</strong> labrum with minute,<br />

triangular, medial tooth, apex <strong>of</strong> tooth well<br />

separated from apex <strong>of</strong> mentum. Apex <strong>of</strong> mentum<br />

with medial notch. Antenna 9-segmented;<br />

club approximately equal to other<br />

segments combined, approximately equal to<br />

length <strong>of</strong> frons. Pronotum: Surface with scattered<br />

setae; setae long, tawny. Surface<br />

sparsely punctate, with moderate punctures.<br />

Marginal bead present apically (except medially)<br />

and laterally, absent basally. Elytron:<br />

Surface glabrous; longitudinal striae weakly<br />

punctate; intervals impunctate. Suture<br />

apically rounded. Pygidium: Width approximately<br />

1.7 times length medially. Surface<br />

smooth, flat, sparsely punctate; punctures<br />

moderate, glabrous (except near apex); setae<br />

long, tawny. Venter: Thorax densely setose;<br />

setae long, tawny to golden-brown. Mesothoracic<br />

process reduced to nub adjacent to<br />

mesocoxa. Abdomen sparsely setose; setae<br />

moderate, tawny. Apical spiracles not extruding.<br />

Legs: Protibia with 3 teeth in apical half;<br />

first and second teeth subequal in size; third<br />

tooth shorter, removed slightly from apical<br />

teeth. Mesotibia and metatibia widest<br />

apically. Protarsomeres 2-4 wider than long,<br />

cup-shaped. Protarsomere 4 with weak<br />

internoapical stridulatory ridge. Protarsomere<br />

5 with weak internomedial stridulatory<br />

tooth. Mesotarsomere 5 and metatarsomere 5<br />

without internal tooth. Unguitractor plate cylindrical,<br />

with 1 apical and 1 subapical seta.<br />

Modified protarsal claw with length approximately<br />

equal to protarsomere 5, thickened<br />

and elongated 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 1.4<br />

times longer than length <strong>of</strong> parameres.<br />

Parameres with weakly curved dorsally.<br />

Female (n=1). Length 18.0 mm, width<br />

10.4 mm. As male except in the following respects.<br />

Color dorsally yellowish-tan; broad<br />

black band along apex and base <strong>of</strong> head; black<br />

band along lateral, apical and suture margins<br />

<strong>of</strong> elytron. Head: Antennal club slightly longer<br />

than segments 2-6. Legs: Protarsomere 4<br />

without internoapical stridulatory ridge.<br />

Protarsomere 5 without internal tooth or<br />

swelling. Modified protarsal claw with ventral<br />

tooth, 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 />

dorsal color green or yellowish-tan with a<br />

broad black band along the apex and base <strong>of</strong><br />

the head and along the lateral, apical and suture<br />

margins <strong>of</strong> the elytron; frons sparsely setose<br />

laterally; frontoclypeal suture complete;<br />

apex <strong>of</strong> labrum with a reduced, triangular<br />

tooth not overlapping the mentum; mentum<br />

with a medial notch; antenna 9-segmented;<br />

pronotum sparsely setose, with weak maculations;<br />

elytron without distinct, yellow, longitudinal<br />

lines; elytron sparsely setose at the<br />

base; elytral apices not capable <strong>of</strong> completely<br />

covering the pygidium; mesothoracic process<br />

nub to weakly projecting apically; apical abdominal<br />

spiracle not protuberant; mesotarsomere<br />

5 and metatarsomere 5 without an<br />

internal tooth; parameres with the apex<br />

rounded, not expanded.<br />

DISTRIBUTION (Fig. 73). Known only from<br />

one locality: Anta, Cusco, Perú.<br />
