Thanks for reporting the issue. I used your repro at https://github.com/woloski/AspNetWebApiWithSubdomains and did some debugging.

Here is why it is happening. The HttpDomainRoute.GetRouteData is not being called because it was wrapped by an internal class called HttpWebRoute in Web API. When you use config.Routes.Add method to add your custom route, instead of calling the HttpDomainRoute.GetRouteData, it will simply call the System.Web.Routing.Route's implementation of GetRouteData. That is why you see the rest of parameters being mapped correctly except the tenant.

I can't think of any easy workaround on top of my head. I can file a issue at the codeplex site at http://aspnetwebstack.codeplex.com/ to track this issue.
