摘要

The larval development of three crabs of the Varunidae family, (Hemigrapsus sanguineus, H. pen-icillatus, and H. longitarsis), widely spread in Russian waters of the Sea of Japan, were studied under laboratory conditions. At a temperature of 20-22 ℃ and a salinity of 32‰ about 30% of larvae a complete developmental cycle, including five zoeal stages and megalopa. Took from 22 to 30 days. All larval stages are illustrated and described in detail. Zoea 1 and zoea II of the studied crabs are not distinguishable. Zoea III-V of these species differ in the number of dorsomedial setae on the abdominal somite 1 and in the number of setae on the poster-odorsal arch. The megalopae of three Hemigrapsus species possess a different number of segments, aesthetascs and setae on the antennular exopod. In spite of the great similarity of larvae of genera Hemigrapsus and Erio-cheir, the latter possesses a number of distinctive features in all developmental stages, supporting the separation of these genera.
