A New Species of Szeptyckitheca (Collembola, Symphypleona, Sphyrothecinae) from Brazil.

A new species of the genus Szeptyckitheca is described from the Biological Reserve of Serra do Japi, São Paulo State, Brazil. All species of the genus present trochanteral spine on the first and third legs, cephalic chaeta A1 often absent. The presence of spine in all trochanters, chaetal row F in head, and abdominal and antennal segments with long bristles with capitate apex are relevant features that distinguishes the new species from all known species of the genus. A key to the identification of the species of Szeptyckitheca is presented.
