HERMATOBATES, NEW GENERIC RECORD — HERRING 129 



Styliform processes of the 8th abdominal segment prominent, 

 rather slender, acute at apices, covered with long hairs, dorsal lobes 

 of 8th segment enlarged and conspicuous, covered with dense pubes- 

 cence; genital capsule large. 



Total length, holotype male, 3.45 mm., greatest width 1.60 mm. 



Female unknown. 



Type locahty: 14°56' S., 146°!' W. (Tuamotu Archipelago, 

 French Oceania) collected at light by Martin W. Johnson, Jan. 21, 

 1953. Holotype (USNM 66876). 



Diagnosis: This species superficially resembles djiboutensis C. and 

 M. but differs from all known species of Hennatobates by the structure 

 of the anterior femur and tibia. No other known species has such a 

 large spine on the base of the femm' or the socket at the base of the 

 tibia for the reception of the apical spine of the femur. In addition, 

 the head is four or more times as wide across eyes as length of head 

 along midline, and the smuate margin of the metasternum bears 

 very small black spmes or mmute tubercles, 



China and Usinger (1950) recorded H. haddoni from the Marquesas, 

 on the basis of a single immature specimen collected by Miss Evelyn 

 Cheesmau at Tahuata. It seems unlikely that this record refers to 

 H. haddoni since there are now two distinct species known in Central 

 Polynesia, and there is no other record of H. haddoni from east of New 

 Caledonia.
