Unlike most Phortica species, this one can be determined also according to its distinctive female genitaia. If you make their preparation, you will understand the peculir name of this species... See its description.

I will have a closer look, to find out about the meaning behind its specific epithet. BTW, the gallery pictures of this species apparantly await a re-naming since several years now...

I do not recognize any of the structures illustrated by Jan in his description of semivirgo or of variegata illustrated in the same paper... Paul - - - - Paul Beuk on https://diptera.info

And I failed to get hands on any publication with the female parts illustrated, only males. To the Macá 1977 revision paper I don't have access. Maybe someone reading this thread can help But has the leg coloration ever shown to be not reliable distinguishing the two?
