semilunar in form. Caudal rami about twice as long as they are broad, and slightly 

 divergent, outer edge with a slender bristle near the tip, middle apical seta of 

 moderate length, with the proximal part somewhat thickened and sharply marked 

 off from the thin setiform terminal part, dorsal seta issuing near the inner edge 

 of the ramus, which here forms a slight bulging. Eye inconspicuous. Anterior 

 antennae nearly as long as the cephalic segment, and clothed in their outer part 

 with slender bristles, 1st joint scarcely more than half as long as the 2nd, both 

 together exceeding in length the remaining part of the antenna, sensory filament, 

 as usual, issuing from the 4th joint. Posterior antennae with the distal joint much 

 shorter than the proximal one, outer ramus very small, issuing near the base of 

 the proximal joint, and tipped with a single slender seta. 1st pair of legs with 

 the inner ramus nearly as long as the outer, proximal joint with a slender seta 

 inside, distal joint a little longer, linear in form, and carrying on the tip 2 un- 

 equal geniculate setae accompanied inside by a small bristle, outer ramus with 

 its 3 joints of about equal size, the terminal one armed at the end with 2 spines 

 and 2 geniculate setae. The 2 succeeding pairs of essentially the same structure 

 and size, both with the inner ramus scarcely more than half the length of the 

 outer. 4th pair of legs conspicuously larger than the preceding ones, the outer 

 ramus being almost twice as long, with its first 2 joints considerably produced, 

 terminal joint somewhat incurved and armed at the end with 4 coarsely spinulose 

 setae of unequal length; inner ramus shorter than the 1st joint of the outer, and 

 tipped with a single spiniform seta finely ciliated in its outermost part. Last 

 pair of legs extremely small, each forming a subtriangular lamella edged with 8 

 unequal setae. Ovisacs narrow oblong in form, each containing only 3 large ova 

 arranged in a single row. 



Male somewhat smaller than female, and having the genital segment 

 distinctly subdivided. Anterior antennae more strongly built and slightly hinged, 

 4th joint a little dilated and subdivided near the end. Outer ramus of 2nd pair 

 of legs carrying at the tip a very large, incurved, falciform claw, exceeding in 

 length the whole ramus, and clothed inside with slender spinules. Inner ramus 

 of 3rd pair of legs peculiarly transformed, exhibiting 2 unequal appendages issu- 

 ing from a short basal part, the outer one forming a thin plate exserted into 2 

 finely ciliated setae, the inner one a straight spine with 2 hook-like ledges inside 

 near the end. Last pair of legs still smaller than in female, with the marginal 

 setae less developed. 



Colour yellowish grey. 



Length of adult female 1.20 mm.
