Bdellocephala annandalei Ijima et Kaburaki, 1916, is an endemic planarian o
f Lake Biwa-ko in Central Japan. This lake-dwelling species inhabits the mu
ddy bottom of the northern basin of the lake (20-103 m in depth). The speci
es is characterized by its comparatively large size, uniformly light brown
coloration, two small eyes, and a subterminal, ventral adhesive organ on th
e frontal end. A detailed taxonomic redescription of B. annandalei is given
here and compared with the other three Far Eastern and Kamchatkan Bdelloce
phala species inhabiting epigean waters.
