Diagnosis	Diagnosis (genus). This new genus can be distinguished from other genera of the Dipsadidae by the presence of deeply divided hemipenial lobes with lobular projections that expand beyond the tip of the sulci, the latter ending on the middle of the lobes and opening at the base of a small vestigial apical disk (Zaher & Prudente 2019). Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data to their customers. These details, e.g. detailed descriptions or comparisons (about 1835 characters) are available for collaborators and contributors. Please contact us for details.

Etymology	Named after Dr. Jose Steinbach (1856-1929), a botanical and zoological collector in Argentina and Bolivia for the Field Museum. The genus name Baliodryas is a masculine noun from the Greek βαλιóς, spotted, dappled, and δρυας, a kind of snake (Heitsch, 1963; Leigh, 2016).
