Remarks The lectotype for Galleruca obsoleta is designated here to have a unique bearer of this name and the standard for its application. Klug (1829) listed this species as present in Suriname (as Galeruca obsoleta ). Later, this species was placed in the genus Oedionychis Latreille, 1829 (as Oedionychus ) by Heikertinger & Csiki (1940) . The rationale of this decision is unknown, and there is no indication that the authors have seen the type of Fabricius. Probably based on Heikertinger & Csiki (1940) , Bechyné mentioned this species in his unpublished catalogue as Alagoasa obsoleta . Since there was no record of this species in any other paper of Bechyné, we suspect that Bechyné made this new (unpublished) combination solely to solve any incertae sedis, without studying the type. Nevertheless, this species clearly does not belong in Oedionychina , but rather Disonychina based on the following characters: frontal ridge long, about twice as long as clypeus; pronotum quadrate, anterolateral callosity of pronotum strongly rounded, apical metatarsomere not globosely swollen. Within Disonychina, it belongs to Phenrica .
