Schizopygopsis sewerzowi Herzenstein, 1891
Schizopygopsis sewerzowi Herzenstein, 1891: 196. Type locality: Lake Bulunkul and Karasu River, Amu Darya basin, Pamir mountains.

DISTRIBUTION IN TAJIKISTAN: Pamir region of Amu Darya basin (localities 40–44, 47–49).
CONSERVATION STATUS IN TAJIKISTAN: Not known; not known (sensu IUCN; Freyhof et al., 2022).
SPECIMENS EXAMINED: IBIW_FS (n = 41) (Artaev et al., 2024). FMNH: 145623, 145625, 145626, 145628, 145629, 145631–33, 145635, 145640, 145643, 145646.
COMMENTS: Nikolskiy (1938) suggested that the difference between main diagnostic characters (eye size and body height) of Schizopygopsis stoliczkai and Schizopygopsis sewerzowi is insufficient to classify them as a different species. Our genetic data confirm the validity of S. sewerzowi. In particular, samples from the Pamir region (GenBank acc. nos. PP993467–68) differ (p -distance = 1.3%) from samples of S. stoliczkai from its type basin, the Indus River (KY032326, 1118 bp), in cytochrome b sequence. In addition, Schizopygopsis sewerzowi is known to have up to four trophic ecomorphs in young Pamir lakes (e.g., Yashilkul) that are divergent in mouth types and feeding modes (Savvaitova et al., 1988; Komarova et al., 2021). It is still unknown whether sympatric ecomorphs are genetically differentiated or not.
