E. irinae is one of six crane fly species in the genus Elephantomyia described from the Baltic amber, the others being E. baltica, E. brevipalpa, E. bozenae, E. longirostris, and E.

The five specimens were first studied by paleoentomologist Iwona Kania, of the University of Rzeszów, whose 2015 type description for the species was published in the journal PLoS ONE.

[2] The E. irinae type specimen is a well preserved male that is approximately 9.5 mm (0.37 in) long, not including the rostrum.

The head has a rostrum that is 2.41–2.82 mm (0.095–0.111 in) long, just over half the length of the fore-wing and shorter than the abdomen.

The wings are between 3.49 and 8.5 mm (0.137 and 0.335 in) long with a pale brown pterostigma that is oval in shape.
