Chandraniscus negoescuae George 2004, n. sp.
Chandraniscus negoescuae n. sp. (figure 7) Diagnosis. Chandraniscus with cephalon having a convex anterior margin and lacking a median projection. Posterior three pereonites showing a clear decrease in width from pereonites 5–7. Pleotelson shield-like, with the sharp posterolateral angles and the ur...

(figure 7) Diagnosis. Chandraniscus with cephalon having a convex anterior margin and lacking a median projection. Posterior three pereonites showing a clear decrease in width from pereonites 5–7. Pleotelson shield-like, with the sharp posterolateral angles and the uropods extending beyond the rounded apex of the pleotelson.

Depth is the minimum depth of occurrence; distribution is the general zoogeographic area of distribution. *Eurybathyal species. Material examined.

Description. Body oval, cephalon broadly rounded anteriorly without a median projection. Cephalon almost twice as long as the first pereonite.

Pereonite 5 significantly longer than either pereonite 6 or 7. Pleotelson shield-like, with posterolateral angles produced, slightly beyond the rounded posterior apex. Pleotelson as long as the posterior three pereonites combined. Antenna 1 with basal peduncular article partly concealed by the cephalon and second article elongated, with a flagellum of five articles. Antenna 2 with four peduncular articles, basal two articles short, articles 2 and 3 elongated, with a flagellum of 11 articles.
