摘要：

Drosophilidae (Diptera) are well known for tremendous variability in sperm length as great as that found among vertebrates and invertebrates together. Paradoxically, the great length (> 1 mm) of Drosophila sperm creates difficulties for measuring them. Evidence is provided that the length of giant sperm can be indirectly, albeit reliably, estimated using the regression lines between sperm and testis or receptacle lengths, established from 26 species with short- and mid-length sperm. Using this method, the sperm length in Drosophila hydei was estimated to be about 17 mm, which would be the longest in the animal kingdom. The phylogenetic relationships between species are discussed.
