Abstract

The Russian endemic crustacean Arctodiaptomus (Haplodiaptomus) kamtschaticus Borutzky, 1953 was found in a new habitat—a small unnamed lake of the Vilyuchinsky Nature Park on the Kamchatka Peninsula. The morphology of the species has been studied in detail using a scanning electron microscope. The mandible, rostrum, and Schmeil’s organ on the middle segment of the endopodite of the 2nd pair of swimming legs were described for the first time. The description of the morphology of the fifth pair of male and female legs has been significantly supplemented.
