) shows paired short plumose setae to either side of the telson nubs and associated long, erect seta dorsal to each nub. The nub magnifications show that the nubs are actually cusped and the erect setae are ringed at their tips by rows of scales. Presumably, the erect setae have a sensory function, perhaps for position within the tube and the cusped nubs may assist with gaining a purchase within the tube. Possibly the plumose setae are mechanoreceptive as well (Kauffmann 1994).

In both specimens, the epibionts were concentrated on the anterior of the body, coating the dorsum and second gnathopods. This pattern suggests that the animals were partially tubicolous during the time of infestation. Movement within the tube may have prevented epibiont accumulation on the posterior part of the body. The cleaning action of the first gnathopods may have prevented epibiont growth on body parts within reach, such as the antennae. That epibiont growth was able to establish in such quantity on these males suggests that the males had not molted for some time, and that they were senescent and not able to prevent epibiont settlement.
