Abstract. Two new genera and species ofParalimnini, Ctenotettix kirgysiciis Novikov
and Anufriev, n. gen. and n. sp., and Triasargus ancoratus Novikov and Anufriev, n.
gen. and n. sp., and a new species of Ulopini, Neobufonaria milkoi Novikov and Anu-
friev, n. sp., from the western Tien Shan of Kyrgyzstan are described and illustrated.
Ecological notes are included for N. milkoi.
