Caracteres que la definen: seta ioIII en posicion 1/2, setas amm de estructura similar a las pmI, nunca mas largas ni fuertes, alas cafe, antenonero III castano, con la base ligeramente clara, pedicelo con un ensanchamiento poco desarrollado, seta poI ausente (a veces), tergito IV sin ctenidia. Los caracteres expuestos son los derivados del trabajo de Moundy Marullo (1996), sin embargo, la posicion de las setas ioIII es informada por estos autores como 2, mientras que en el holotipo es 1/2, de igual forma el pedicelo del antenomero III no resulta poco evidente sino que su contorno es un ensanchamiento continuado, a diferencia de las demas especies de este grupo, en las que el anillo subbasal hace una fuerte demarcacion.
