We describe a new species of Hydrolaetare from the eastern lowlands of Bolivia. The new species differs from the other two congeners in (1) Finger II and III with lateral fringes only on the inner side; (2) relative length of first finger; (3) palmar tubercle distinctly larger than thenar tubercle; (4) toes semiwebbed; and (5) coloration. Moreover, the advertisement call of the new species differs from that of its congeners. Some information about its natural history is given.
