Measurements

Lectotype ( Fig. 14 ): LB = 4.64 mm; WB = 2.81 mm. Paralectotype 1 ( Fig. 15 ): LB = 5.98 mm; WB = 3.48 mm. Paralectotype 2 ( Fig. 16 ): LB = 6.13 mm; WB = 3.78 mm.

Remarks

The lectotype for Galleruca decemguttata is designated here to have a unique bearer of this name and the standard for its application. Both the lectotype and the paralectotypes are completely intact. We confirm the correct placement in the genus Alagoasa Bechyné, 1955 based on the following characters: frontal ridge narrow, vertex with a few punctures, sides of pronotum widely explanate, body broadly curved (see also Konstantinov et al. 2022).
