1. All Veliidae genera can be distinguished using male bugs. The following genera CANNOT be distinguished using female bugs; Tarsoveloides, Microvelopsis and macropterous forms of Microvelia.

Males are usually distinguished from females by the presence of a distal grasping comb (GC) - a row of minute stout hairs - on each fore tibia.

Male genital segments are usually large, where the female segments are usually more compact.
