Abstract

Parachristianella parva sp. nov. is described from the spiral valve of Urobatis maculatus Garman, 1913 from the Gulf of California, Mexico. The new species is distinguished by its small size and small number of testes per segment (8–10). Parachristianella trygonis Dollfus, 1946 is reported from the spiral valve of Mobula munkiana Notarbartolo di Sciari, 1987 and from Dasyatis brevis (Garman, 1880), whereas the adult of Parachristianella dimegacantha Kruse, 1959 is described for the first time from the spiral valves of Urotrygon simulatrix Miyake and McEachran, 1988; Sphyrna zygaena (Linnaeus, 1758); and Dasyatis longus (Garman, 1880), all from the Gulf of California.
