COELIA UNGUICULARIS OHAUS F<br />

PARALECTOTYPE A.B.T.SMITH 2002” (yellow<br />

label, handwritten and typeface). Ohaus<br />

(1904b) did not explicitly state how many<br />

specimens were in the type series. He examined<br />

material from “Ecuador, Zamora<br />

(Baron)” that I was unable to track down. The<br />

existence and location <strong>of</strong> any further remaining<br />

paralectotypes are unknown. Type locality:<br />

Mérida, Venezuela.<br />

DESCRIPTION. Male (n=12). Length 18.9-<br />

19.7 mm, width 10.5-11.8 mm. Color <strong>of</strong> dorsal<br />

surface olive green or dark yellow; elytral interval<br />

3, 7 with weak yellow, longitudinal<br />

stripe; elytral interval 5 with wide, strong,<br />

yellow, longitudinal stripe. Ventral surface<br />

yellowish-green to reddish-brown (especially<br />

metasternum) or dark yellow; abdominal sternites<br />

<strong>of</strong>ten with dark brown to black latitudinal<br />

stripe. Body ovate, convex. Head: Dorsal<br />

surface glabrous. Frons rugopunctate, clypeus<br />

rugose, punctures moderate. Frons not depressed.<br />

Frontoclypeal suture complete.<br />

Clypeal apex broadly rounded, weakly deflexed.<br />

Eyes separated by approximately 3.6<br />

transverse eye-widths. Labrum rugopunctate,<br />

with moderately large, setose punctures, setae<br />

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

medial tooth, apex <strong>of</strong> tooth weakly<br />

overlapping apex <strong>of</strong> mentum. Mandibular<br />

scissorial region with 1 apical tooth, molar<br />

region with strong lamellae. Maxilla with 1<br />

small interior tooth; 1 large, cup-like, exterior<br />

tooth. Apex <strong>of</strong> mentum with acute medial<br />

tooth weakly curved into oral cavity. Antenna<br />

10-segmented; club approximately equal to<br />

other segments combined, slightly longer<br />

than length <strong>of</strong> frons. Pronotum: Surface gla-<br />

brous, densely punctate, with small and moderate<br />

punctures. Marginal bead weak laterally,<br />

absent elsewhere. Elytron: Surface<br />

glabrous; longitudinal striae impressed, punctate;<br />

punctures moderate; intervals moderately<br />

punctate, punctures small and<br />

moderate. Suture apically with weak spine or<br />

nub. Pygidium: Width approximately 2.1<br />

times length medially. Surface weakly convex,<br />

moderately punctate; punctures moderately<br />

large, setose in apical half; setae short, tawny.<br />

Venter: Thorax densely setose except sparsely<br />

setose medially, setae tawny. Mesothoracic<br />

process moderately produced, projecting anteriorly<br />

past mesocoxa; shape conical-elongate,<br />

apex rounded, dorsoventrally flattened. Abdomen<br />

sparsely setose, setae tawny. Apical 2 spiracles<br />

not extruding. Legs: Protibia with 3<br />

subequal in size teeth in apical half.<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 with<br />

internomedial, stridulatory tooth. Mesotarsomere<br />

and metatarsomere 5 with internobasal<br />

tooth or swelling. Unguitractor plate<br />

cylindrical, with 2 apical setae. Modified<br />

protarsal claw longer than protarsomere 5,<br />

more thickened and elongate than other claw,<br />

laterally flattened, apex unevenly bifurcate.<br />

Modified mesotarsal and metatarsal claws<br />

elongated with ventral tooth, not thickened.<br />

Male Genitalia: Phallobase approximately 1.7<br />

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

Parameres with apex angled ventrally.<br />

Female (n=10). Length 18.0-22.5 mm,<br />

width 11.0-13.4 mm. As male except in the<br />

following respects. Head: Antennal club approximately<br />

equal to segments 2-7. Legs:<br />

Protarsomere 3-4 without internoapical stridulatory<br />

ridge. Protarsomere 5 without internal<br />

tooth. Modified protarsal claw with<br />

ventral 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 />

frontoclypeal suture complete; apex <strong>of</strong> the labrum<br />

with a broad, triangular tooth weakly<br />

overlapping the mentum; mentum with a distinct<br />

tooth not curved into the oral cavity;
