Bovallius, 1887a: 38; 1890: 69; Spandi, 1927: 191; Page, 1960: 30; 

 Pillai 1966: 179. 



Length of sexually mature individuals up to 10 mm. 



The head with rostrum is approximately equal to the total length of 

 the first four pereon somites. Viewed dorsally, the rostrum is triangular, 

 viewed laterally, it is sharply narrowed and pointed. 



The 2nd segment of pereopods I has a straight anterior margin, a 

 distally bulged posterior margin, and is equal in length to the rest of 

 the leg; the 4th segment is distally broadened and posteriorly bears two 

 distal setae; the 5th segment is almost triangular, its distal margin twice 

 the width at the base and about equal to the length of segment along the 

 posterior margin, and the posterior distal angle stretched into a pointed 

 denticle; the subchela is formed by the denticulate posterior margin of the 

 movably articulated 6th segment and distal margin of the 5th segment; 

 the distal parts of the 5th-6th segments are covered with stiff setae. The 

 2nd segment of pereopods II is longer, and longer than the rest of the leg; 

 the proportions and ornamentation of the subchela are similar; and the 6th 

 segment is relatively longer and narrower than in pereopods I. In pere- 

 opods III-IV the posterior margin of the 4th-6th segments bears sparse
