Five new ostracod species belonging to the subfamily Trachyleberidinae have been described. They are Paragrenocythere monilis and Peloriops levisulcata from the Maastrichtian of Iraq; Oertliella petraensis from the early Palaeocene (middle – late Danian) of Jordan; Reticulina syriaensis from the Palaeocene of Syria and Reticulina ninurta from the middle – late Eocene of Iraq.

Ostracods are common microcrustaceans in inland waters, widely used as (palaeo-) environmental indicators. Information on their species distribution worldwide is extremely fragmentary, and usually biased towards some regions, hampering attaining a general view of biogeography. The Iberian Peninsula, the Balearic Islands Macaronesia considered biodiversity hotspots part Mediterranean Region, who...

A new interstitial ostracod, Semicytherura uzushio sp. nov., is described from the southwest of Japan, and the details of the carapace characters of Semicytherura mukaishimensis Okubo, 1980 are redescribed. Semicytherura uzushio and S. mukaishimensis live interstitially in the intertidal and infralittoral zones, respectively. They have the smallest carapaces among the known Semicytherura specie...
