Abstract
This report is the second of a series devoted to redescriptions of members of Baikalomoraria based on modern research methods. An illustrated redescription of the female and male of Moraria (Baikalomoraria) werestschagini Borutzky 1949, a rare endemic harpacticoid species from the littoral zone of Lake Baikal, is presented. Since the type material of the species was lost, it became necessary to select a neotype. For the first time, the morphology of this species was studied in detail using scanning electron microscopy, and a description of the mouthparts and antennules was given. The description of the swimming legs was significantly supplemented and the structure of the genital field was shown, including data on the morphological variability of limbs. In addition, we briefly describe the fifth copepodite stages of the male and female. The fifth copepodite stage of the female was found to bear long apical setae on the caudal rami, vs adult females characterized by short setae more similar to spines.
