“…Two distinct evolutionary trends have occurred within this group, one comprising the subfamilies Lestremiinae and Cecidomyiinae, and the other leading to Lasiopteridae [Dallai and Mazzini, ; Dallai et al, ]. The first trend still retains a geometric—though deeply altered—organization of the axoneme, which is characterized by the absence of the central complex (substituted for by elongated, axial mitochondria), by a progressively increasing number of doublets (up to 2500 in Asphondylia) , and by the loss of the inner dynein arms, which are only present in the less evolved Lestremiinae [Dallai and Mazzini, ; Dallai et al, ]. However, and albeit only under particular conditions, these sperm cells are motile [Lupetti et al, ; Mencarelli et al, ].…”

“…In fact, we have reported that the loss of the central pair/radial spoke complex is not only followed by the loss of the inner dynein arms, but also results in a reduced complement of heavy chains in the outer dynein arms [Lupetti et al, ; Mencarelli et al, ]. The sperm cells of the species belonging to the other trend, on the contrary, assemble 9 + 0 axonemes that are able to maintain their ultrastructural integrity only in their very proximal part, after which doublets appear scattered in the cytoplasm [this article; Dallai and Mazzini, ; Dallai et al, ]. Both dynein arms are lost in this evolutionary lineage, and sperm cells are immotile.…”
