The present paper gaves the description of a new species named Barbronia yunnanensis sp nov and the diagnosis of Salifa lateroculata (Kaburaki, 1921) which is a new record in China Type specimens of B yunnanensis sp nov and some specimens of S lateroculata are deposited in the Institute of Hydrobiology, Academia Sinica, Wuhan Barbronia yunnanensis sp nov (Fig 1)This new species resembles B weberi Blanchard,1897 and B zhejiangna Yang, 1996, two species in China, but differs from them in the following characters 1) Gonopores separated by 512-6 annulis are in the segments Ⅺ b4/b5 and Ⅻ b4 in the new species while those separated by 5 annulis are in the segments Ⅻb1 and Ⅻ/ⅩⅢ in B weberi, and those separated by 4 annulis are in the segments Ⅻb2/a2 and ⅩⅢb1/a2 in B zhejiangna 2) Anus of the new species is in the inverted 3/2 annuli while those of the other two species are in the inverted 2/1 annuli 3) The complete segment of the new species has 6 annulis, b1(c1+c2)=b6(c11+c12)>b2=b4=b5>b3,while that of B weberi has 5 annulis, b6 (c11+c12)>b1=b2=a2(b3+b4)=b6, and that of B zhejiangna has 5 annulis, b6(c11+c12)>b1=b2=b5>a2(b3+b4)So far as we know, five species of the genus Barbronia Johanssom, 1918, have been described The present species differs from all of the known species in major aspects and considered as new to scienceSalifa lateroculata (Kaburaki, 1921)Length 11-23 mm; maximum width 10-25 mm; daiameter of caudal sucker 07-13 mm First pair of eyes on dorsum of segments Ⅳ , another four to six pairs of accessory eyes on segments Ⅳ to Ⅸ a2 Gonopores are separated by two and one-half to three annuli, the male being Ⅻb2/a2 or a2 and the female very constantly Ⅻ/ⅩⅢ Complete segments in mid-body strictly five annuli and the usual size relation of these annuli being b6>a2=b5>b2>b1 Ejaculatory duct without preatrial loop extending anteriorly to ganglion Ⅺ
