Distribution: Pacific Ocean (coast of Peru, the Solomon Sea; 40° 21' 

 S 158° W); Indian Ocean north of madagascar and in the central part 

 (10° S, 86° 30' E). Found in through catches from depths greater than 

 1,000 m to the surface. 



3. Mimonecteola mixta Vinogradov, 1964 (Fig. 39) 



Vinogradov, 1964: 122. 



Length of sexually mature specimens 9,5-1 1 mm. 



Pereopods III and IV are identical in structure but pereopods IV 

 longer; the distally almost not broadened 4th segment of pereopods IV 

 is 2/3 the length of the 5th segment; the 6th segment is equal to or 

 somewhat shorter than the 5th. 



Pereopods V: the 4th segment is slightly shorter than the 5th; the 

 narrower 6th segment has parallel margins, does not narrow distally, and 

 is nearly equal in length to the 5th segment. In females the 6th segment 

 is armed in the distal part of the posterior margin with a short row of 

 strong paired setae forming an almost palmate margin, much shorter than 

 the length of the claw. In males the row of setae on the palmate margin 

 is longer but the setae themselves are thinner; the claw is longer and 

 stronger in females. Pereopods VI: the thin 6th segment is 1.5 times 

 longer than the 5th while the 4th segment is somewhat shorter than it. 

 Pereopods VII: the 5th segment is equal to the 4th and 2/3 the length of 

 the 6th; the latter almost does not narrow distally, its posterior margin 

 extending beyond the base of the claw and forming the spoon-shaped 

 depression so characteristic of the Lanceolidae; the anterior margin of 

 the segment has a depression in the distal part into which the short curved 

 claw may be retracted, forming a shape similar to the subchela. 



The triangular telson reaches half the length of the basipodite of 

 uropods III. 



Distribution: Pacific Ocean in the region of the deepwater Philippine 

 Trench, and 13°35' N 101°45' W; eastern part of the equatorial region 

 of the Indian Ocean (0°, 83° E). It is found in through catches from 

 depths of several thousand meters to the surface. 



4. Mimonecteola subchelata Vinogradov, 1964 (Fig. 40) 



Vinogradov, 1964: 124. 



One sexually immature female 8 mm long is known. 



The general shape, structure of antennae, mouthparts and pereopods 

 I-II are the same as in other species of the genus. 



Pereopods IV; the distally slightly narrowing 6th segment is slightly 

 shorter than the 5th, which also narrows only slightly distally; the claw 

 is long, about 1/3 the length of the 6th segment. Pereopods V: the 6th 

 segment is oblong ovate, slightly longer than the 5th and 2/3 the length 

 of the 2nd segment; its convex posterior margin is armed with long setae,
