Classification

Johnston placed Travisia in Arenicolidae and Grube (1850) moved it to Opheliidae. Morphologically Travisia species are similar to scalibregmatids, with their rugose epidermis, grub-like appearance and (mostly) lack of ventral groove, except they lack a T-shaped prostomium. Early molecular work appeared to confirm a scalibregmatid relationship but apparently was based on unreliable sequences. Persson & Pleijel (2005) placed Travisia in Scalibregmatidae. Sequences of Rousset et al (2007) placed Travisia back in the opheliids, but Paul et al (2010) rejected those sequences and used their own sequences (not from the type species) to reconfirm that Travisia have Scalibregmatidae affinity, although they conservatively place it as sister taxon to the Scalibregmatidae sensu stricto. Law et al. (2014:566) place Travisia molecularly in Scalibregmatidae without qualification.
