It's interesting in that there doesn't seem to be a feminine equivalent but then mabe there aren't any succession rules that would require one.

The American Heritage Dictionary says:
Related or akin by the father's side; also, sprung from the same male ancestor; ; in this sense it is a correlative of uterine.

The OED has uterine Obsolete. rare. plural. Children or offspring of the same mother.
No suggestion as to what replaces it.
