MONOGRAPHIC REVISION OF PLATYCOELIA 113 moderately large, setose punctures, setae tawny. Apex of labrum with triangular, medial tooth; apex of tooth broadly truncate, extending past apex of mentum. Apex of mentum with triangular medial tooth curved into oral cavity. Antenna 10-segmented; club slightly shorter than other segments combined, slightly shorter than length of frons. Pronotum: Surface glabrous, densely punctate, with small or moderate punctures. Marginal bead weak apicolaterally, absent elsewhere. Elytron: Surface glabrous; longitudinal striae weakly punctate, punctures moderate with dark coloration; intervals densely punctate, punctures small. Suture angled apically, without spine. Pygidium: Width approximately 3.3 times length medially. Surface weakly convex, moderately to densely punctate; punctures moderate, glabrous except near apex; setae short, tawny. Venter: Thorax moderately setose (except medially on metasternum), setae white. Mesothoracic process strongly produced, projecting anteriorly to protrochanter; shape conical-elongate, apex rounded; ventrally flattened. Abdomen glabrous. Apical spiracles not extruding. Legs: Protibia with 3 subequal in size teeth in apical half; apical 2 teeth longer; third tooth weak, obsolete. Mesotibia and metatibia widest medially. Protarsomeres 2-4 wider than long, cup-shaped. Protarsomere 4 with internoapical stridulatory ridge. Protarsomere 5 with internomedial stridulatory tooth. Mesotarsomere and metatarsomere 5 with internobasal tooth. Prounguitractor plate cylindrical, with 2 subapical setae. Mesounguitractor plate and metaunguitractor plate cylindrical, with 2 apical setae. Modified protarsal claw with length approximately equal to protarsomere 5, thickened and elongate when compared with other claw, laterally flattened, apex unevenly bifurcate with 1 bifurcation twisted beneath the other in ventral view. Modified mesotarsal and metatarsal claws elongated with ventral tooth, not thickened. Male Genitalia: Phallobase 1.9 times longer than length of parameres. Parameres dorsoventrally flattened, apicomedially acute. ALLOTYPE. Female: length 33.1 mm, width 19.0 mm. As male except in the following respects. Legs: Protarsomere 4 without internoapical stridulatory ridge. Protarsomere 5 without internal tooth. Mesotarsomere and metatarsomere 5 with weak internobasal swelling. Modified protarsal claw with ventral tooth, not thickened. VARIATION. Male (n=9). Length 28.0-32.2 mm, width 17.0-18.9 mm. Female (n=1). Length 31.6 mm, width 19.3 mm. Paratypes similar to holotype and allotype except in the following respects. Color of body sometimes greenish-yellow or darkened to dark green or brownish-green. Pygidium: Disc moderately setose. ETYMOLOGY. I am very pleased to name Platycoelia paucarae after my friend and colleague Aura Paucar-Cabrera. Aura has had an interest in Platycoelia for many years and has graciously provided a wealth of information for this revision. This species is also native to Ecuador, which is Aura’s homeland. DIAGNOSIS. This species is distinguished from all other species in the genus Platycoelia by the following combination of characters: clypeal apex weakly reflexed; frontoclypeal suture complete; labrum with a well-developed, truncate apical tooth strongly overlapping the mentum; mentum with a distinct tooth curved into the oral cavity; antenna 10segmented; pronotum surface densely punctate with mix of small and moderate punctures; elytron without distinct, yellow, longitudinal lines; elytral apices capable of completely covering the pygidium; pygidium entirely setose; mesothoracic process light in color than the metasternum; metasternum with a dark medial patch; abdominal sternites dark; protibial apical 2 teeth adjacent, located in the apical quarter of the protibia; protibial spur noticeably shorter than the adjacent tibial apex; protarsomere 3 in males without a distinct apical stridulatory patch; modified protarsal claw in males laterally flattened; mesotarsomere 4 and metatarsomere 4 in males with an apical stridulatory ridge; mesotarsomere 5 and metatarsomere 5 with an internobasal tooth; parameres with the apex dorsoventrally flattened.
