jointed, scarcely reaching to the middle of the first joint 

 of the inner branches. The middle joint of the onter 

 branches is considerably longer than either the first or 

 third joints. The outer branches of the second, third, and 

 fourth pairs of feet are three- jointed. The inner branches 

 are short and two-jointed. The fifth pair of feet resemble 

 those of L. curticauda in shape, but the basal joint is much 

 larger, and the outer joint is wider at the apex than at the 

 base. The inner margin of the basal joint is furnished 

 with three plumose setae. There is also one apical seta. 

 The apex of the outer branch is furnished with five setae 

 of unequal lengths. Caudal furca robust, and longer than 

 the last abdominal segment.
