鸟类寄生饰带类线虫一新种(旋尾目:针形科)

A NEW SPECIES OF ACUARIOIDES FROM BIRDS(SPIRURIDA: ACUARIIDAE)

本文报道采自河北省平山县的鸟类寄生饰带类线虫一新种,河乌针形线虫,新种Acuariacincli sp.nov.寄生于褐河乌Cincls pallasii(Temminck)的砂囊角质层中。模式标本保存于河北师范大学生物系。

Acuaria cincli sp. nov. (Fig, 1—6)Holotype♂, allotype♀, paratypes 2♂♂, 2♀♀were collected from the gizzard of a bird, Cinclus pallasii (Temminck) from Pingshan County (38°41′N, 113°67′ E), Hebei Province.The new species is similar to A. microecae Mawson, 1972 in the cordon length, but differs from the latter in the spicules (1) The left spicule longer than right one in the former versus two equal length spicules in the latter. (2) 6 pairs of postanal papillae in the former but 7 pairs latter. (3) Vulva position, a little forward from the middle of the female body in the former but a little backward latter. (4) The egg size bigger in the former.The new species resembles A. minuta Williams, 1929 in the shape and size of spicules, but can be distinguished from the latter in having shorter cordons and 6 pairs of postanal papillae ( 7 pairs in the latter), and in caudal length of male.
