( Fig. 9 )

Diagnosis. Platydracus scabrosus can be recognized among other South American species of Platydracus by its head, pronotum and elytra black to piceous black, and the abdomen black with its last visible segment brown to reddish brown. Length 15.0–17.0 mm.

Distribution. From northern Argentina, Uruguay, Paraguay and southern Brazil ( Herman 2001; Newton, pers. com.).

Bionomics. Unlike nearly all other Neotropical Platydracus , it seems to be found often outside forested areas, apparently even in urban areas, according to collection records (Newton, pers. com.).
