with 1 short and 2 long terminal spinous bristles and a long stout 

 process with annulations and a rough surface of small pustules distally. 



Fifth limb (figs. 5e-i): First joint with 2 large teeth: proximal 

 tooth trident with 3 bristles (fig. 5/); distal tooth bifid (fig. 5h). 

 Second joint prolonged distally forming long fangiike tooth followed 

 along the inner margin by a single tooth and 2 trident teeth (fig. 5e) ; 

 posterior siu-face with 2 stout spinous bristles and a minute bristle 

 (fig. 5i) ; inner edge of joint with spinous bristle (fig. 6i). (It was not 

 possible to discern mth certainty that this bristle was not in fact on a 

 proximal margin of the distal tooth of the first joint.) Third joint 

 with 2 short hirsute bristles (fig. 5i). Fourth joint hirsute with 1 

 short and 2 long terminal bristles and 1 short subterminal bristle 

 (figs. 5g,i). Epipodial appendage with 42-46 bristles. Single endite 

 with 2 short bristles. 



Sixth limb (fig. 6a): First endite with 1 to 2 bristles; 2nd endite 

 with 2 bristles; 3d and 4th endites each with 5 to 6 bristles; end joint 

 with 9 to 10 bristles (end joint of late instar with only 7 bristles) ; single 

 bare bristle in place of epipodial appendage. Surface with clusters 

 of hairs; end joint fringed with hair. 



Seventh limb (figs. Qb-d) : Symmetrical terminus with opposing 

 combs of 5 or 6 teeth (all teeth not shown in figs. 6 b,c) . Adult with 

 6 terminal and 6 to 8 lateral bristles (instars mth fewer bristles) , each 

 bristle with 1 to 5 bells (fig. Qd) and short marginal spines distally.

Furca (figs. 6e, J-h) : Each lamella with 8 to 10 claws; 3rd claw thinner 

 than 4th but about the same length ; each claw separated from lamella 

 by suture with exception of 9th and 10th claws which, when present, 

 appear as nodes. Claw 1 with stout spines in row proximally on 

 lateral margin, slender spines distally on lateral and medial margins, 

 1 large spine near middle of medial margin, and groups of slender
