摘要
描述了栖息于云南丽江的艾纳螺科1新种宋氏小索螺Funiculus songi sp.nov.。模式标本保存于南京大学。宋氏小索螺最膨大处出现在次体螺层以上4个螺层,一侧轮廓线弧形,壳口轴唇缘极扩展及测量特征等与小索螺属其它6个已知种(德氏小索螺F.delavayanus、羸小索螺F.debilis、优小索螺F.probatus、左弓小索螺F.asbestinus、皮小索螺F.coriaceus和劳氏小索螺F.laurentianus)相区别。新种首次描述了小索螺属贝类的生殖系统构造。对小索螺属的鉴别特征进行了补充,并给出了该属的种检索表。
The genus Funiculus Heude, 1888, comprising F. delavayanus, F. debilis, F. probates, F. asbestinus, F. coriaceus and F. laurentianus before this work, was revised in brief. The 7th species Funiculus songi sp. nov. was described from Yunnan, based on the diagnostic shell shape and the apertural structure. Besides, this species gives the chance for learning the anatomy of the genus.
