COPEPODA CHONIOSTOMATA 



CHONIOSTOMATIDAE 



SphaeroneUa photidis spec. iiov. (fig. 3) 



Female : The body is rather broader than long and devoid 

 of hairs. The second maxilla is long and slender. The ter- 

 minal joint with its claw is one-third the length of the basal 

 joint. The maxilliped is slightly shorter than the head. The 

 basal joint is three times as long as wide and unarmed. The 

 terminal joint bears a single claw with a spur at its base. 



Male : Unknown. 



Length : 0.52 mm. 



Type: B 133. 



Host and site: Marsnpinm of Phot is reinhardi (Grnstacea 

 Amphipoda). 



Remarks : This species and *S*. pilosa spec. nov. are the first 

 Choniostomatidae to be described from Phofis reinhardi. 



SphaeroneUa pilosa spec. nov. (fig. 2) 



Female: The body is globular and its whole surface is 

 sparsely beset with conspicuous hairs. The maxilliped 

 barely exceeds the head in length. A chitinous bar is present 

 at the bases of the maxillipeds. The basal joint is three 

 times as long as wide and widest at the end of the proximal 

 third. It bears five setae on the lateral margin, one on the 

 medial margin, three at the mediodistal angle, and two at 

 the laterodistal angle. In addition, there is a row of short 

 hairs across the middle of the anterior face. The distal joint 

 with its claw is three-fourths the length of the basal joint. 

 The claw bears a fine hair near its center. 



Male : Unknown. 



Length : 0.45 mm. 



Type: B168. 



Host and site: Marsupium of Phofis reinhardi.
