. This species is named after the late Dr. Katherine D. Hobson, in recognition of her publications about polychaetes and especially because of her two books about British Columbian polychaetes, both made with Dr. Karl Banse, which are very useful and widely employed beyond the Canada-USA Pacific border. The epithet is a noun in the genitive case.

; because of reductions in papillae size and number of transverse rows, it can be hypothesized that it lives in rocky shore interstices. The broken cephalic cage might indicate that the specimens were gathered by breaking rocks. The possibility that members of the species actually bore into calcareous substrates, or even only furnish a gallery inside them, deserves closer study.
