 right. Inner caudal seta reduced; left terminal seta se- 

 cond from inner somewhat longer than right; small 

 outer (sixth) seta present.

 segments; segment 1 without cluster of spines or 

 setules; segments 8 and 9 (fused) relatively long; seg- 

 ment 25 not reduced. IV-2s, le; VIII-2s, le; XV-
