ETYMOLOGY — This new species is named after Eddie A. Ueckermann, eminent South African acarologist.

REMARKS — The spermatheca of this species strongly resembles the type mentioned by Chant & McMurtry (2005a) as typical for most of the Ueckermannseius species then known. In one of the type specimens, one of the spermathecae ( Figure 21 C, left) is similar to the type, mentioned by Chant & McMurtry (2005a); the other spermatheca of the same specimen and the spermathecae of other type specimens correspond with Figure 21 C (right).

Ueckermannseius saltus resembles this new species, but it has shorter j1 and Z5, longer j3, much shorter macrosetae on legs, no macroseta on leg I. Ueckermannseius aequidens is also similar to this new species, but it has much shorter j1, shorter peritreme (extending between j1 and j3), much shorter macrosetae on legs and no macrosetae on tibiae III and IV.
