New species of the genus Calocalanus (Copepoda, Calanoida) from the bank Saia-de-Malia (in the Indian Ocean)

C. nanus sp. n. is similar to C. ovalis but differs from it by the structure of the Vth pair of swimming legs (4-segmented in C. nanus and 3-segmented in C. ovalis; the external edge of the Ist exopodite segment of the IInd pair of swimming legs is even in C. nanus and there are three small spines on it in C. ovalis). C. aculeatus sp. n. differs from C. cristalli by several small spines along the edge of the Ist exopodite segment of the IInd pair of legs and also by the number of segments of the Vth pair of legs (four in C. aculeatus and two in C. cristalli). C. regini is similar to C. elegans but differs from it by the structure of the Vth pair of swimming legs (3-segmented ending with bristle as long as the leg in C. regini and 2-segmented with long apical bristle in C. elegans).Новые виды копепод, принадлежащие к роду Calocalanus, описанному Гисбрехтом (Giesbrecht, 1892), найдены нами в планктонных сборах экспедиции Института биологии южных морей АН УССР (ИнБЮМ) на экспедиционном судне «Профессор Водяницкий» в 1985 г. в Индийском океане в районе банки Сая-де-Малья (Маскаренский хребет). При сборе проб использовали сеть Джеди диаметром 36 см с газом № 49. Материал фиксировали 4%-ным формалином. Голотипы новьх видов Calocalanus хранятся в ИНБЮМ (Севастополь)
