is directly connected with the postabdomen and proceeds as a very long, proximally thicker spine-like structure, variable in length (138.0–405.0 %, on average 173.0–296.0 % of body length), thus exceeding the body length by 1.4–4.0 times. Generally, the caudal process is strongly chitinized and its surface covered by numerous minute spinulae.

Pairs of claws sit either close or quite distant to each other (e.g., distance between postabdominal claws and proximal claws of caudal process (interclaw distance) constitutes 6.7–56.8 %, on average 14.8–36.5 % of body length). Between the latter, the thickness of the structure may be different: 2.3–7.9 %, on average 4.3–6.1 % of body length. Borders separating old molted integuments of caudal process with claws normally are quite conspicuous.

demonstrate the increased morphological variability of hybrid individuals in comparison with the parental species which is especially characteristic of shape and size of postabdominal and caudal process’ claws as well as of interclaw distance (the highest values of CV = 50.2–55.6 which were observed in populations from Rybinskoe, Uglicheskoe reservoirs and Siberian lakes Chany and Gusinoe). The high variability of length of distal segment of tl I, caudal process, and interclaw thickness (the highest values of CV = 20.3–38.8 were detected in specimens from the same water bodies as well as in those from Gor’kovskoe Reservoir) was observed as well.

Therefore, it is not possible to discriminate morphologically among hybrid and parental specimens which can co-occur.
