Lepidepecreella charno, new species 



(Fig. 17) 



Diagnosis: Rostrum short; article 6 of gnathopod 1 longer than ar- 

 ticle 5 ; epistome not marked ventrally with notch ; posterior lobe of 

 article 4 on pereopods 3 and 4 only half as long as article 5, this lobe 

 on pereopod 5 as long as article 5 ; coxa 5 broader than coxa 6 ; third 

 pleonal epimeron with serrate posterior edge, lacking distinct tooth at 

 posteroventral corner ; telson evenly convex apically. 



Holotype: AHF No. 5911, female, 4.5 mm. Unique. 



Type locality: Station 6091, San Clemente Basin, off Baja Cali- 

 fornia, 32° 10'30" N, 117°57'10"W, 1895 m, January 14, 1959. 



Relationship: Differing from both L. cymba and L. ctenophora in 

 the short posterior lobe of article 4 on pereopod 3, from L. cteno- 

 phora by the broad coxa 5 which in that species is narrower than coxa 



6, from L. emarginata in the convex telson and long sixth article of 

 gnathopod 1, from L. ovalis in the short rostrum and lack of a tooth 

 on the third pleonal epimeron and from L. bidens in the linear, un- 

 produced second article of pereopod 3.
