Belostoma bachmanni De Carlo, 1956 

( Figs. 3DView Figure 3, 10AView Figure 10)

Known distribution: Known only from the locality of the type series ( Paraguay, Department. Concepción, Puerto Vallemí) ( De Carlo, 1956) and from Brazil, Purus river and Solimões river (Estévez, unpublished data).

Notes: This species is poorly cited in the literature and unknown by many researchers studying giant water bugs. There were doubts about which species group Belostoma bachmanni  belongs to and its range of distribution. Recently, Estévez (unpublished data) included this species in the B. triangulum group of Lauck (1964), considering the triangular prosternal keel and male genitalia, which have arms of phalobase long, extending beyond the flat ventral diverticulum. The males examined were 19.5-20.0 mm in length and the greatest body width were 9.6-10.2 mm; females were 19.8-21.0 mm in length and the greatest body width were 9.5-10.2 mm, both male and female have flattened body. This species appears to be relatively abundant along the Negro river and its tributaries.
