Research paper

Summary.

The opilionid, Parampheres ronae, has a pair of orange markings on its carapace at a location where some other opilionids discharge yellowish, quinone-containing defensive fluid. P. ronae itself produces a defensive secretion, but the fluid is quinone-free and nearly translucent. We suggest that the orange markings in P. ronae are aposematic in the sense that they are imitative of the glandular emissions of quinone-producing opilionids.

Key words.
