Аннотация:A species of the mostly deep-sea parasitizing nematode family Benthimermithidae has been for the first time discovered alive in marine aquaria of St. Petersburg City, Russia. Parasitizing juveniles, young females and a young male adult were found in small crustaceans: Ostracoda, Isopoda, Tanaidacea and Amphipoda. The nematode is described as Trophomera granovitchi sp. n. which is characterised by relatively large and distinctly edged amphideal fovea and is distinguished from related T. laubieri, T. filiformis, T. petterae, T. pacifica, T. aptera and T. leptosoma predominantly in size of body and organs. Male of T. granovitchi sp. n. while differing from females in smaller body size has the same type of the amphideal fovea. Parasitizing juveniles T. granovitchi sp. n. differ from adults in having a normal pharynx with a small anterior stylet-like structure, normal midgut, tail with a vestigial terminal spinneret, and by the absence of obvious sensilla. Levels of infection of various host crustaceans by nematodes vary considerably. Adult specimens emerging from various hosts differ in body size.
