摘要：

The adult stage of Prebaetodes Lugo-Ortiz & McCafferty is described for the first time based on reared specimens from Venezuela. The adults of the genus can be distinguished from other genera of South American Baetidae by the following combination of characters: paired marginal intercalaries of forewings, anal area rounded and relatively narrow; hind wings absent; male eyes turbinate, contiguous basally and slightly separated dorsally; segment I of forceps without distomedial projection, segment III elongated and uniformly slender. Additionally, a new species, P. meridinensis is described based on nymphs and imagines, and notes on its biology are included. The genus is herein redefined based on variations of characters observed in the new species and the adult generic description.
