ABSTRACT. A new species of coral reef mantis shrimp of the genus Gonodactylellus spiridonovi sp.n. is described from the Red Sea, constituting the twentyfourh species in the genus and fourth from the northwestern Indian Ocean. The new species aligns with those species of Gonodactylellus having short accessory median carinae on the telson that do not extend anteriorly beyond the posterior one-third of the median carina and lacking dorsal spinules on the telson surface (G. annularis Erdmann et Manning, 1998, G. erdmanni Ahyong, 2001, G. incipiens (Lanchester, 1903) and G. viridis (Serиne, 1954)) but is distinguished from all of the species by the shorter anterior submedian carina on the telson. A key to the species of Gonodactylellus from the northwestern Indian Ocean is provided.

KEY WORDS: Crustacea, Stomatopoda, mantis shrimp, Red Sea, Indian Ocean.
