Review of the Genus Odontodactylus 

 (Crustacea: Stomatopoda) 



By Raymond B. Manning 



Chairman, Department of Invertebrate Zoology 



The genus Odontodactylus was proposed by Bigelow (1893) as a 

 subgenus of Gonodactylus, from which the former differed in having 

 the dactylus of the raptorial claw armed with teeth. Odontodactylus 

 was recognized subsequently as a full genus by Bigelow (1894). 



Representatives of the genus are most abundant in the Indo-West 

 Pacific region, but one species is known to occur in the Atlantic. 

 Comparison of a series of 0. havanensis from the Atlantic with speci- 

 mens of 0. brevirostris from the Indo-West Pacific in connection with 

 a revision of the western Atlantic stomatopods suggested that the 

 specimens were conspecific. The comparative study further sug- 

 gested that some characters previously used for species recognition 

 in the genus were unreliable and that other characters might be of 

 more value. 



The current study shows that Odontodactylus contains five species, 

 of which one described herein is new. 



Methods. — The terminology of the carinae of the telson in Odonto- 

 dactylus used herein is shown in figure 1. There are some differences 

 between these terms and those proposed by Kemp (1913). The 

 latter are somewhat confusing in that the anterior extension of the 

 carina of the submedian marginal tooth is called the "intermediate";
