摘要

A new species of gastrosaccid mysid, Gastrosaccus yuyu, is described from the higher tidal levels of wave-exposed surf beaches of Java, Indonesia. It belongs to that group of Gastrosaccus species with a fringe of slender spine-like filaments along theposterodorsal margin of the carapace, and, in having a mid-dorsal apophysis on the fifth abdominal somite in the adult and filaments which extend onto the postero-lateral lobes of the carapace, is close only to G. sorrentoensis. It is distinct in havingfewer marginal carapace filaments than G. sorrentoensis, as well as apical telson spines which are hardly longer than the sub-apical lateral spines and are separated from those spines by a gap distinctly larger than those between the previous spines, amore pronounced rostrum, and a distinct conformation of the distal tip of the mandibular palp, inter alia. Gastrosaccus yuyu is collected commercially by artisanal fishermen in Java, and cooked into a fried rice-flour crisp biscuit, known locally as "peyek".
