Abstract:
The paper records the rediscovery of the rare Urodontidius enigmaticus Louw, 1993 in South
Africa, based on specimens reared from galls in the succulent leaves of Ruschia versicolor. The original
account of some of the morphological characters of the species is corrected, and its habitus, antennae,
pygidium and genitalia are illustrated. Its life history and galling habit on its host plant are described
and illustrated, and its larva is compared with those of the genera Urodontellus Louw and Urodontus
Louw, which represent different larval types with different life histories. The silk-spinning habits of
the Urodontellus larva are briefly described. A tribute to the late Schalk Louw is presented, together
with a list of his publications on weevils.
