Distribution: A warm-water species. It is distributed in the Atlantic 

 (from 51° N to 32° S), Indian (almost everywhere in the tropics, the 

 Great Australian Gulf), and Pacific (south of 40° N, Kuroshio, Hawaiian 

 Islands, Nasca ridge. New Zealand) oceans, and in the Mediterranean 

 Sea. It inhabits predominantly the surface to 300-400 m layer.

Glaus, 1879b: 36 (Thamyris); 1887: 59; Stephensen, 1925a: 

 ne.—bovallii Stebbing, 1888: 1553.— latipes Stebbing, 1888: 1550.— 

 inaequipes Stebbing, 1888: 1549. 



Length of sexually mature specimens up to 12 mm. 



The head is short, rounded, anteriorly not narrowed in either males 

 or females, and its height 1.3 times its length. The basal segment of 

 antennae II in males is longer, and equal to the 2nd segment; the distal 

 segment of the flagellum is 1/5 the length of the preceding segment. 



The 2nd segment of pereopods I in males is curved, as in 

 B. crusculum, in females linear; the 4th segment is markedly broadened 

 distally; the 5th segment is wider than long, its anterior distal process 

 short, the posterior distal angle only slightly less than a right angle, and 

 both margins bear three-four low teeth each, whose margins are also 

 finely denticulate; the 6th segment has bulged margins and the posterior 

 one bears three-five denticles. The 2nd segment of pereopods II is longer
