). Head, pronotum and elytra with thin dense punctation, in addition pronotum and elytra with small and shallow punctures, and microsculptured. At posterolateral corners of pronotum, punctures almost a little joined and corrugated. Elytra lacking deeply impressed striae. Two continuous rows of punctures are most obvious and divide the elytra in three more or less equal intervals. A third and a fourth row of punctures also present, albeit less distinct and more fragmented. These occur between the two first distinct rows and between the second distinct row and the elytral margin. A fifth row suggested between the two outermost rows by a few spaced out punctures, almost unidentifiable in most Malagasy specimens seen but more distinct in specimens seen from mainland Africa. Appendages testaceous to rufus.

<paragraph pageId="0" pageNumber="19">This species was described from Lubumbashi, DR Congo, and has not been recorded from Madagascar before. Earliest record found is from November 1946. It seems to be a dispersive good flier and often collected at light so its presence in Madagascar is therefore not surprising. However, it is not widespread in Madagascar as far as we know. In fact, the known distribution is restricted to the surroundings of the capital and east of the capital along the main national route towards Toamasina, which could suggest a recent incidental human-mediated introduction from mainland Africa.</paragraph>
