WALLISI OHAUS F PARALECTOTYPE<br />

A.B.T.SMITH 2001” (yellow label, handwritten<br />

and typeface). One female paralectotype<br />

at MNHN labeled a) “Bogota” (handwritten),<br />

b) “Ex Musæo Mniszech” (typeface), c) “Ohaus<br />

determ. Pl. Wallisi Ohaus F.” (typeface and<br />

handwritten), d) “Dr Ohaus Vidit 1903.” (typeface),<br />

e) “PLATYCOELIA WALLISI OHAUS F<br />

PARALECTOTYPE A.B.T.SMITH 2001” (yellow<br />

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

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

were in the original type series. Ohaus also<br />

examined specimens from “Manizales<br />

(Steinheil)” and “Ecuador, Sara-yacu<br />

(Buckley)” but I was unable to locate these<br />

paralectotypes. The existence and location <strong>of</strong><br />

additional remaining paralectotypes are unknown.<br />

One specimen labeled “COLU<strong>MB</strong>IA<br />

S.d.Popayan” also has Ohaus’ orange cotype<br />

label. Since this locality was not mentioned in<br />

the original description, the specimen is not<br />

part <strong>of</strong> the type series. Type locality: Frontino,<br />

Antioquia, Colombia.<br />

DESCRIPTION. Male (n=18). Length 21.3-<br />

23.0 mm, width 11.2-13.6 mm. Color olive<br />

green or brownish-yellow; elytral interval 2,<br />

4, and 6 with yellow, longitudinal stripe; head,<br />

pronotum, scutellum, and elytron with yellow<br />

margin. 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 rounded. Eyes separated by approximately<br />

4.1 transverse eye-widths. Labrum<br />

sparsely punctate, with moderately<br />

large, setose punctures, setae tawny. Apex <strong>of</strong><br />

labrum with triangular, medial tooth, apex <strong>of</strong><br />

tooth separated from apex <strong>of</strong> mentum. Mandibular<br />

scissorial region with 2 teeth, molar<br />

region with strong lamellae. Maxilla with 3<br />

teeth. Mentum with apicomedial notch. Antenna<br />

10-segmented (<strong>of</strong>ten appearing 9-segmented);<br />

club approximately equal to<br />

segments 2-7 (2-6 in apparently 9-segmented<br />

individuals), slightly longer than length <strong>of</strong><br />

frons. Pronotum: Surface glabrous, moderately<br />

punctate, with small and moderate<br />

punctures. Marginal bead weak laterally, absent<br />

elsewhere. Elytron: Surface glabrous;<br />

longitudinal striae impressed, punctate;<br />

punctures moderate; intervals moderately<br />

punctate, punctures small. Suture apically<br />

with weak spine or nub. Pygidium: Width approximately<br />

1.5 times length medially. Surface<br />

weakly convex, densely punctate to<br />

rugopunctate; punctures moderately large,<br />

setose (near apex); setae short, tawny. Venter:<br />

Thorax moderately setose (except sparsely setose<br />

medially), setae tawny. Mesothoracic process<br />

moderately produced, projecting<br />

anteriorly past mesocoxa; shape conical; ventrally<br />

flattened. Abdomen sparsely setose, setae<br />

tawny. Apical spiracles not extruding.<br />

Legs: Protibia with 3 subequal in size teeth in<br />

apical half. Mesotibia and metatibia widest<br />

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

cup-shaped. Protarsomere 3-4 with internoapical<br />

stridulatory ridge. Protarsomere 5 with<br />

internomedial, stridulatory tooth. Mesotarsomere<br />

and metatarsomere 5 with<br />

internobasal tooth or swelling. Unguitractor<br />

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

protarsal claw with length greater than<br />

protarsomere 5, thickened and elongate when<br />

compared with other claw, laterally flattened,<br />

apex unevenly bifurcate. Modified mesotarsal<br />

and metatarsal claws elongated with ventral<br />

tooth, not thickened. Male Genitalia: Parameres<br />

approximately 1.1 times longer than<br />

length <strong>of</strong> phallobase. Parameres with apex<br />

rounded.<br />

Female (n=22). Length 23.4-27.8 mm,<br />

width 12.5-15.3 mm. As male except in the<br />

following respects. Legs: Protarsomere 3-4<br />

without internoapical stridulatory ridge.<br />

Protarsomere 5 without internal tooth. Modified<br />

protarsal claw with ventral tooth, not<br />

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 reduced, triangular tooth not<br />

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

notch; elytron with distinct, yellow, longitudinal<br />

lines on striae 3 and 5; elytral apices<br />

not capable <strong>of</strong> completely covering the pygidium;<br />

metasternum and abdominal sternites<br />

green or yellow; mesothoracic process
