Pseudocumatidae (lat.) - a family of sea cumaceans from the class of higher crayfish ( Malacostraca ). About 30 species ^[2] .

Petalosarsia declivis

Description

Sea (some brackish), small crustaceans , resembling tadpoles in appearance: shell-swollen cephalothorax and thoracic region (covered with common carapace shell) are enlarged and contrast with a thinner abdomen ( pleon ) ending with a tail fork. Anal lobe ( telson ) developed, but small in the form of a rounded plate, spines absent. Antennas of females are small, rudimentary. The mandibles are scaphoid. Uropods (elongated limbs of the sixth segment) have a one-segmented internal branch (endopodite) ^[3] . 19 species of Pseudocumatidae constantly live in conditions of low salinity and inhabit the Caspian Sea , brackish water areas of the Azov and Black Seas , as well as estuaries and basins of the rivers flowing into them: the Volga , Don , Dniester , Southern Bug , Danube ^[4] .

Systematics

It has about 30 species and 13 genera. The family was first isolated in 1878 by the Norwegian zoologist Georg-Ossian Sars ( Georg Ossian Sars ; 1837-1927). In the Russian waters of the Sea of Japan , representatives of the first kind and one species are found ^[3] .
