Fig. 3. Phronima bowmani (after Shih, 1991). 



rostrum is wide and at the base of the head there is a weakly pronounced 

 dorsal depression, barely exceeding the length of the first segment of the 

 perion. 



This species is closely affiliated with S. challengeri and especially 

 to S. porcella. It is distinguished from the former by the absence of 

 a distal acute-angled projection of article 2 of pereopod VI; from the 

 latter by the structure of articles 5 and 6 of pereopod II, the palmar 

 region of which has coarse, sharp teeth. None of the known species 

 of Streetsia have a similar structure for pereopod II. A characteristic 

 feature of S. palmaspinosa is a well-pronounced stepped notching along 

 the lower edge of epimere III. 



Specimens have been collected in the Pacific Ocean along the Nasca 

 Ridge, and in the Indian Ocean along Sal de Malya and Walter's banks.
