Diplonevra Lioy, 1864

Diplonevra Lioy View in CoL (total of 18 photos of seven mating events examined: Figure 3A–D View Figure 3 )

The photos show a general mating position for Diplonevra with a few slight differences present in some of them. In one mating event, the female abdomen seems especially bent upward ( Figure 3A View Figure 3 ) but this could be artefactual as it was not seen in the other photos. In two other photos, a structure of the female terminalia is contacting the male ( Figure 3B View Figure 3 ). We identified this structure as two enlarged lobes that together form a roof-like plate covering the cerci. In another mating event ( Figure 3C,D View Figure 3 ), the male lifts both forelegs during mating, a behaviour not seen in other photos of Diplonevra . We do not know of any modified structure in the Diplonevra foreleg that could be related to this behaviour.
