at the tip ; end segment lobed, with a short spine on each lobe and a 

 longer one at the apex. Total length, 2.3-2.6 mm.

 American shores. The fingerlike processes on the genital segment, 

 two in the female and one in the male, and the form of the fifth 

 legs in both sexes, furnished the best means of identification.
