The larvae of Nitocra spinipes Boeck, 1865 were reared at 2$0^{\circ}C$ and 33.3$\textperthousand$ in the laboratory. These species passed through six nauplii stages and the first copepodid appeared in 8-10 days. Nauplii of N. spinipes is distinguished by characteristics of the appendage setation and caudal setae. The number of segments of antennal and mandibular exopodites in harpacticoida is discussed within familial level.
