Family SYNOPIIDAE ( =Tironidae) 

 Bruzelia ascua, new species 



(Figs. 45, 46) 



Diagnosis: Rostrum long, straight, nearly in line with cephalic axis, 

 dorsum of head with two sharp bilateral keels, eyes not visible; pereo- 

 nite 1 lacking dorsal tooth, all following pereonal, metasomal and the 

 first two urosomal segments with a long, acute, dorsal projection each; 

 each pereonal and metasomal segment with a subdorsal tooth and a 

 lateral tooth, the lateral teeth of pereonites occurring at ventral mar- 

 gins just above coxae; coxae 5 and 6 each with a laterally projecting 

 tooth; coxa 4 much shorter than 3, with a posterior cusp and dorso- 

 posterior excavation; second and third pleonal epimera each with a 

 slender, long, unserrated posteroventral tooth; second articles of pereo- 

 pods 3-5 each with 2 or 3 medium-sized posterior cusps, posteroventral 

 corners strongly produced. 



Holotype: AHF No. 5812, male, 4.7 mm. Unique. 



Type locality: Station 5938, Patton Escarpment, 32°-04'-30" N, 

 119°-43'-20" W, 1687 m, November 9, 1958. 



Relationship: This species differs from Bruzelia dentata Stephen- 

 sen (1931a) in the extra set of teeth located subdorsally and laterally 

 on the pereonal and metasomal segments, the unserrated peonal epim- 

 era and the presence of dorsal cephalic keels. 



Bruzelia ascua differs from B. australis Stebbing (1910) in the pres- 

 ence of lateral and subdorsal pereonal teeth and the presence of dorsal 

 teeth on pleonites 3-5. 



Other species of Bruzelia have fewer dorsal teeth or much smaller 

 dorsal carinae than those mentioned above.
