are hygropetric (Figs 34-36), and most are known from only one or few localities. They are characteristic of marginal and small aquatic habitats on inselbergs or other rock surfaces (Figs 34, 36) and the margins of waterfalls (Fig. 35) in the Guaiana Shield region of northern South America (Figs 31-33). They can often be extremely abundant in these habitats. Several of the species co-occur, but others are the only known species at some sites (Figs 31-33).

, were based on few specimens. Each of the male holotype specimens had been previously dissected, and it clearly appears, based on acquisition and examination of new material, that the male median lobes had been switched between the two and each median lobe suffered some damage during its dissection.
