Antennae obscurae, basi pallidae. Caput pallidum. Thorax marginatus, pallidus, immaculatus.

Measurements

Lectotype ( Fig. 29 ): LB = 5.91 mm; WB = 3.64 mm.

Remarks

The lectotype for Galleruca oculata is designated here to have a unique bearer of this name and the standard for its application. The lectotype is missing segments 3–11 of the right antenna and segments 5–11 of the left antenna. As already indicated in Zimsen (1964), there is one specimen included in the type series that is likely misplaced and seems to be conspecific with Galleruca nobilitata ( Fig. 5 ). This is also indicated on a printed label, probably added by Zimsen. 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.
