Oncideres ( Multicinctipenna) Özdikmen, 2025j: 3240 . Syn. nov.

Oncideres ( Psyllotoxus) Thomson, 1868: 74 . Syn. nov.

Oncideres ( Taricanus) Thomson, 1868: 73 . Syn. nov.

Remarks. Özdikmen (2025j) divided Oncideres into four subgenera and reported: “It is interesting that the members of this species-rich genus were not evaluated according to elytral design so far.” In our view, Özdikmen’s (2025j) generic concept is entirely artificial, relying merely on superficial morphological features. This pattern is consistent across the subgenera he established or revalidated in the studies referenced in the present work.

Still according to Özdikmen (2025j) on Oncideres : “In first group [ Oncideres ( Oncideres) Lacordaire, 1830: 183 ], antennae without fringes of dense, long black hairs on the inner sides of first five antennomeres (especially 1st, 3rd and 4th antennomeres); elytra always with prominent, few or many, more or less raised tubercles or granules only at the base, the remaining parts of elytra, ignoring the remaining elytral design, without raised tubercles, granules or dots;” “In second group, antennae without fringes of dense, long black hairs on the inner sides of first five antennomeres (especially 1st, 3rd and 4th antennomeres); elytra with few or many, prominent tubercles or granules especially at the base, and few or many, more or less irregularly distributed, suferficial dots in the remaining parts of elytra (almost completely or at least to apical half); and therefore, ignoring the remaining elytral design, the basal decoration with tubercles, granules or dots always clearly larger than decoration of the remaining parts of elytra;” “In third group, antennae without fringes of dense, long black hairs on the inner sides of first five antennomeres (especially 1st, 3rd and 4th antennomeres); elytra without prominently raised tubercles anywhere; elytra with few or many, small granules or dots especially at the base, and few or many, more or less irregularly distributed, suferficial dots in the remaining parts (almost completely or at least to apical half); therefore, ignoring the remaining elytral design, the basal decoration with granules or dots slightly larger or not (almost same) than the decoration of the remaining parts of elytra;” and “In fourth group, antennae with fringes of dense, long black hairs on the inner sides of first five antennomeres (especially 1 st, 3 rd and 4 th antennomeres); elytra without prominently raised tubercles anywhere; elytra usually completely with many, more or less irregularly distributed, suferficial [ sic, superficial] dots; therefore, ignoring the remaining elytral design, the basal decoration with granules or dots almost same with the decoration of the remaining parts of elytra.”

Again, the division of Oncideres into subgenera has no scientific basis. Souza et al. (2024), based on molecular phylogeny, synonymized Psyllotoxus and Taricanus with Oncideres . We consider the proposal to treat Taricanus and Psyllotoxus as subgenera of Oncideres to be entirely unfounded, especially given the lack of consideration for the reasons behind the original synonymies proposed by earlier authors. Consequently, we reestablish the synonymy between these two genera and Oncideres . Due to the high variability in pubescence patterns, as well as the size and number of elytral tubercles within Oncideres , we are synonymizing Oncideres ( Multicinctipenna) with it.
