Its highly unusual elytral morphology, with a distinct depression around the scutellum, distinguishes it from all known species within the subtribe. In the male specimen, this depression results in a large spade-shaped scutellum that extends out over the elytral suture. Akrobothrus can be separated from other genera of Bothrosternina by a unique combination of characters. The antennal club is elongate and parallel-sided with 3 segments divided by procurved and recurved sutures. The lateral margins of the pronotum are costate and the prothroracic intercoxal piece has a transverse subcarinate ridge.10aAkrobothrus ecuadoriensis1 aDole, Stephanie, A.1 aCognato, Anthony, I.  uhttps://weevil.myspecies.info/new-genus-and-species-bothrosternina-coleoptera-curculionidae-scolytinae-ecuador
