In sex-reversed cave insects, females have the penises (ScienceDaily April 17, 2014): “Although sex-role reversal has been identified in several different animals, Neotrogla is the only example in which the intromittent organ is also reversed,” says Kazunori Yoshizawa from Hokkaido University in Japan.

In weird Brazilian cave insects, male-female sex organs reversed (Reuters Thu Apr 17, 2014 12:09pm EDT): “Evolution of novelties like a female penis is exceptionally rare. That’s why I was really surprised to see the structure,” entomologist Kazunori Yoshizawa of Japan’s Hokkaido University said by email. Yoshizawa said that although sex-role reversal has been documented in several different types of animals, these insects are the sole example in which the “intromittent organ” – the male sex organ – is reversed, Yoshizawa said.
