Pempheridae (Sweepers)
Etymology: Pempheris: Greek, pempheris = the name of a fish (Ref. 45335); familia: Name from Greek 'familia' means ‘‘family’’; the Ogasawara Islands include ca. 30 islands, many of them having been given family-like names; for example, Chichi-jima = father island, Haha-jima = mother island, Ane-jima = older sister island. Ototo-jima, where the type specimens were collected, and Ani-jima, where the underwater photographs were taken, refer to younger and older brothers, respectively..
