Well, I've never seen Z. semifusca, but the upper branch of the posterior fork is supposed to be very weakly developed, which doesn't seem to be the case here. The shape of anepimeron and/or anepisternum is similar in the two genera.
Have a look at the semifusca wing here https://sciaroidea.myspecies.info/taxonomy/44966
