New records of the crangonid shrimp genus Metacrangon Zarenkov, 1965 (Decapoda: Caridea), from the south of Java, eastern Indian Ocean, with description of a new species

Abstract

Three species of the crangonid shrimp genus Metacrangon Zarenkov, 1965 (Decapoda: Caridea), are reported from the south of Java, Indonesia, on the basis of material collected by the South Java Deep-Sea Biodiversity Expedition 2018 (SJADES 2018): M. clevai Kornai, 2012, M. punctata Kornai, 2012, and a new species, M. latirostris. No species of the genus has been heretofore recorded from the surveyed area. Metacrangon latirostris, new species, is distinctive in the genus by having the rostrum much wider than long and the anterior middorsal spine on the carapace located at the postrostral position. Metacrangon clevai and M. punctata, both known from Southwest Pacific localities, are first records for the eastern Indian Ocean.
