Abstract

The new 13+0 axonemal model has been described in the proturanNeocondeellum. All the doublets are devoid of dynein arms and the spermatozoa are immotile. A protruded acrosome is evident in the mature coiled spermatozoa. On the basis of the spermatological results Protentomidae seem closely related to Acerentomidae.

白首乌(昆虫纲,原尾目)精子中的“13+0”轴丝母细胞模式
新的13+0轴索模型已在Neocondeellum前体中描述。所有的双精子都没有动力蛋白臂,精子是静止的。成熟的盘绕精子顶体明显突出。根据精子学结果,蛋白质虫目似乎与Acerentomidae有密切的亲缘关系。
