The type speciemens are deposited in the Laboratory of Fish Pathology, Institute of Hydrobiology, Academia Sinica, Wuhan. Lamproglena semilabecola sp. nov.(Figs. 1—13) Host: Semilabeo prochilus Distribution: Songtao and Yinjiang County, Guizhou Province Measurements(mm): total length, 1.46—1.65; head, 0.31—0.33, width 0.35—0.4;genital segment, 0.13—0.15, width 0.21—0.26; abdomen, 0.52—0.56.
