While examining a collection of Collembola from Illinois, I came across a small specimen which looked like an immature Katiannina (Maynard and Downs, 1951). Using Salmon's key (1964), I traced the species to the tribe Katiannini, of which Katiannina is not a member. The species dealt with in this paper belongs to the genus Polykatianna Salmon (1946).
