Type species — Ozineus elongatus Bates, 1863 (subsequent designation, Thomson, 1864: 322 ). Diagnosis. Lateral tubercles of the prothorax distinct, placed at posterior third; elytra with centrobasal crest, with erect setae on top; femora clavate; ovipositor moderately projected beyond the elytral apex. Number of species currently included: 1. Remarks. As seen above, the other species of this genus were transferred to Sternacutus , only the type species remaining in Ozineus . The genus can be included in the alternative of couplet “25” from Monné et al. (2020) : 25(23). Pronotum with tubercles............................................................

Femora pedunculate-clavate....................................................... Onalcidion Thomson, 1864 – Femora clavate............................................................................ Ozineus Bates, 1863 Note: The discovery of the presence of erect setae on the elytra of Ozineus makes the validity of Onalcidion as a distinct genus very questionable. This is because, apparently, there are no differences securely separating these two genera. However, a full revision of these genera will be necessary to confirm or not the synonymy.
