Remarks

The lectotype for Galleruca sellata is designated here to have a unique bearer of this name and the standard for its application. Although the male specimen is missing the right hind leg and has a slightly damaged right elytron, we chose this specimen as lectotype because some male characters like shape of prosternal process and shape of last abdominal ventrite can be helpful for species delineation in Walterianella (Van Roie unpubl. data). We confirm the correct placement in the genus Walterianella based on the following characters: eyes big, interocular space about as wide as diameter of eye, pronotal borders widely explanate, flattened, prosternal process keeled.
