Abstract

Gaufinia is proposed as a new genus for the Sweltsa lamba (Needham and Claassen 1925) species group, and 5 current and 6 new species are recognized based primarily on scanning electron microscopy of the male epiproct. Males of the new genus are distinguished from all other Chloroperlidae by the presence of a distinctive leaf-like aedeagal lamella. A preliminary key for males of the 11 currently recognized species is presented to assist in identification.


Se propone Gaufinia como un nuevo género del grupo de especies Sweltsa lamba (Needham y Claassen 1925) y se reconocen 5 especies actuales y 6 nuevas basándose principalmente en microscopía electrónica de barrido del epiprocto masculino. Los machos del nuevo género se distinguen de todos los demás Chloroperlidae por la presencia de una distintiva laminilla edeagal en forma de hoja. Se presenta una clave preliminar de los machos de las 11 especies actualmente reconocidas para ayudar en la identificación.
