Island and its port in the Aegean Sea (Brian, 1928, 1928a). For the 

 Indo-Pacific area, it is known from the following localities: Nancowry 

 Harbour and the east coast of Camorta Island in the Nicobar Islands, 

 and Addu Atoll in the Maldive Archipelago (Sewell, 1940). It was 

 found in aU these localities in weed washings.

This species, of which the females measure 1-1.1 mm. and the males 

 0.95-1 mm., is restricted to the Mediterranean, where it has been 

 recorded from Banyuls-sur-Mer, France (Monard, 1928); from the 

 Rovinj, Yugoslavia, area in the Adriatic (Brian, 1923) ; from the islands 

 of Rhodes, Astypalaia, Karpathos, and the port of Syme in the Aegean

 1950, pp. 117, 119. 



This species is known from only the adult male (length 1.014 mm.) 

 and the Vth copepodite stage of the female (length 1.055 mm.). It 

 can be recognized by the curious color pattern and characters of the 

 2nd leg. All specimens originate from weed washings from Nancowry 

 Harbour in the Nicobar Islands.
