D i a g n o s i s: This is the only known Pelonium SPINOLA species from Puerto Rico whose specimens show corrugations on the pronotal and elytral discs.

D e s c r i p t i o n: Size: Length 8.5 mm; width 3.0 mm. Form: As in Fig. 334 . Color: Cranium black; antenna bicolored, antennomeres 9 and 10 yellow, other antennomeres dark brown; prothoracic sternum black; pronotum castaneous, with gold-colored setal wisps; pterothorax black; elytra mostly castaneous, with lighter and darker regions, elytral apex yellow; legs bicolored, femora and tibiae black, tarsi yellow; abdomen mostly dark brown, apical sternites yellow. Head: Cranium coarsely punctate; antenna ( Figs 85, 87 ) capitate, funicular antennomeres shorter towards capitulum, in female ( Fig. 87 ) capitular antennomeres 9 and 10 with short collateral branch, in males ( Fig. 85 ) capitular antennomeres 9 and 10 with long collateral branch, antennomere 11 ovoid; eyes large, coarsely facetted, eye twice wider than frons (EW/FW 55/25). Thorax: Pronotum ( Fig. 183 ) quadrate (PW/PL 130/130), disc corrugated, with central fissure, lateral tubercles well developed; elytral disc corrugated, sculptured with large substriate asetiferous punctures that diminish near elytral apex (EL/EW 360/90). Abdomen: Pygidium transverse / scutiform; aedeagus as in Fig. 242 .

Variation: Length 7.0- 8.5 mm; width 2.5-3.0 mm. Other than body size, the available specimens are quite homogeneous.
