Do any one know the chromesome number of Lumbricus earthworms, except L. castaneus, L. festivus, L. frendi, L. rubellus and L. terrestris? Are there any species currently places in Lumbricus that has another chromosome number then 2n=36?
Up to my best knowledge there are now poliploid speciemens in the genus Lumbricus found so far. (Please note that L. eiseni reported frequently under this name does not belong to the genus Lumbricus but to Allolobophoridella !!!)

Thank you! I assume you mean that there are no polyploid specimens found? I noted that A. eisini is no longer placed in Lumbricus, and that that species also have a different chromosome number
Up to now poliploidy is not registered in any Lumbricus species which is quite interesting, because in other genera with peregrine species polyploidy is fairly common.
