Date:4/17/2014

genital coupling. In other words, it appears that females can hold males very tightly indeed.

The findings pave the way for interesting studies in these insects to learn what makes them so special. Neotrogla offers new opportunities to test ideas about sexual selection, conflict between the sexes, and the evolution of novelty, the researchers say.

"It will be important to unveil why, among many sex-role-reversed animals, only Neotrogla evolved the elaborated female penis," says Yoshitaka Kamimura from Keio University in Japan. For that, the researchers will look into studies of behavior, physiology, and more. First on the list, they say, is to establish a healthy population of the insects in the lab.
