Nilothauma canaima n. sp. from Bolívar State in southeastern Venezuela, Nilothauma granma n. sp. from Granma Province in eastern Cuba and Nilothauma soka n. sp. from Amazonas State in Brazil are described and figured as males. N. canaima can be grouped with Nearctic Nilothauma verrucum Adam and Sæther, but can be separated based on its small size as it has a wing length <1.3 mm and an AR = 0.13. N. granma can be grouped with Nearctic Nilothauma babiyi (Rempel) and Neotropical Nilothauma matogrossense Mendes and Andersen, but can be separated from both as it has a wing with distinct, dark areas. N. soka can be grouped with Neotropical Nilothauma aripuanense Mendes and Andersen, but can be separated based on the shape of the superior volsella as it has a boot-shaped superior volsella with microtrichia only. A key is given to the males of Nilothauma from the New World.
