038F87E01444044BFF3F334BFED0FB4D.taxon	diagnosis	Differential diagnosis. The presence of a complete lateral elytral ridge will readily distinguish P. convexus from species of the related Nematodinus Lea. The sinuous, posteroventrally directed anterolateral pronotal ridges will further separate the species from P. caribicus Muona.	en	Otto, Robert L.

038F87E01444044BFF3F334BFED0FB4D.taxon	description	Redescription. Length 4.0 – 5.5 mm. Width 1.2 – 1.7 mm. Body oblong, elongate; uniformly reddish brown; antennae and legs reddish brown; head, pronotum and elytra clothed with short, recumbent yellowish setae (Fig. 4). Head: Subspherical, without median carina or groove; surfaces shiny, punctures deep and closely spaced; apical margin of frontoclypeal region evenly rounded, more than 2 times wider than base; mandibles stout, bidentate, densely punctate. Antennae: Antennal flagellomeres I – VIII weakly serrate, about 1 / 2 of the length of the body; flagellomere I longer than wide, longer than II; flagellomere II longer than wide, slightly longer than III; flagellomeres III – VIII slightly longer than wide, subequal; flagellomere IX longer than wide, longer than VIII. Pronotum: Surface somewhat shiny, densely and closely punctate; quadrate, with moderate, sharp hind angles; lateral sides parallel-sided at basal 2 / 3, arcuate at apical 1 / 3; disc convex, without fovea; anterolateral ridge short and directed posteroventrally; posterolateral ridge elongate, extending 3 / 4 the length of the pronotum; base sinuous, with short, median groove above scutellar shield. Scutellar shield: Quadrate, subtriangular, punctate and distally rounded. Elytra: Striae vaguely indicated throughout, moreso basally near humeri; interstices flattened; surfaces somewhat shiny, transversely rugose at basal 1 / 2, shallowly punctate at apical 1 / 2.
