| 4 | Apterichtus anguiformis (Peters, 1877) | Jardas (1996) | Not confirmed in the Adriatic Sea. Not listed in the checklist of Jardas (1985), but included in the later book (Jardas 1996) with the note that the single Adriatic specimen had length of 28 cm with no data on locality and date of collecting or on the specimen morphology, and with no reference on the record cited. Criterion 4 is not satisfied since there was no data on locality and date of the personal collecting of specimen.
