Abstract

The larva, deutonymph, female, and male of a new water mite species, Georgella samaraensis, are described and illustrated. Larvae of Georgella are similar to larvae of the genus Hydryphantes, differing in the following characters: basal cheliceral segments have no longitudinal ribs, dorso-distal prominences of the pedipalpal tibia are undeveloped, and the excretory pore is partly surrounded by the anal sclerite. The larva known as G. koenikei (Münchberg, 1936) is erroneously treated as a larva of fresh-water Georgella (Hydrachnidia). The morphology of all the active developmental phases of Georgella strongly differs from that in mites of the genus Hydryphantes. Therefore, the generic status of Georgella should be restored.
