Etymology: Epigonus: Greek, epi = over, in front + Greek, gonio = angle (Ref. 45335); marisrubri: The species is named marisrubri, the Latin translation of "Red Sea". The epithet is composed of the noun mare (sea, genitive case = maris) and the adjective rubrum (red, genitive case = rubri).
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 52 - 200 m (Ref. 93890). Tropical; 30°N - 29°N, 34°E - 35°E
Red Sea: Gulf of Aqaba, Jordan. Only known from the type locality, a coral reef area in front of the Marine Science Station in Aqaba, at the northern tip of the Gulf of Aqaba, Red Sea, where it was found at a depth of only 52 m. First record of the family Epigonidae from the Red Sea, representing the northermost occurrence in the Indian Ocean (Ref. 83754).
