lateral appendages are also different. The lateral appendages are longer 

 and better separated in this new species. The spines on the feet differ 

 also, and the ocular tubercle in the new species is much larger and more 

 prominent.

Genus EURYGYDE Schodte, 1857 



Body relatively compact, with well-defined segments and unusually 

 long lateral processes. Cephalic segment with little-developed frontal part 

 and strongly prominent cervical process for attachment of the ovigers. 

 Caudal segment horizontal, fusiform, expanded in its outer part. Ocular 

 tubercle narrow, marked, distinctly marked eyes. Proboscis of medium 

 size and fusiform, articulated by narrow neck, curved inward on the 

 ventral side. Well-marked joint in the proboscis. Chelifori narrow, 2- 

 jointed. Palpi greatly elongated, curved, 10-jointed. Ovigers usually 10- 

 jointed, marginal spines in a double series serrated, terminal claws dis- 

 tinct. Ambulatory legs slender, with strong bristles. Coxal joints of the 

 female swollen. Tarsal joint very small. Terminal claw short, without 

 auxiliary claws.
