The other types of genders like for your examples might fit under Asexual. I've heard people use Asexual to describe say for example robots in the meaning of lacking a biological gender. I have always locked at it like asexual reproduction as following its "parent" wouldn't be defined as either sex. I guess I could see us trying to think of a better term but I feel it works especially since the like I gave has it say as a possible meaning of "having no sex or sexual organs."
