Frmate.— Body (fig. 1) with moderately broad prosome. Length 
0.83 mm (0.77—0.90 mm) and greatest width (near middle of cephalo- 
some) 0.47 mm (0.43-0.49 mm), based on 10 specimens. Ratio of 
length to width of prosome 1.24:1. Segment of first leg separated 
dorsally and laterally from head by a transverse furrow; lateral 
areas of this segment rounded posteriorly and not expanded. Lateral 
areas of segment bearing leg 2 expanded, those of segment of leg 3 
expanded and slightly truncated, and those of segment of leg 4 small 
and rounded. 
Segment of leg 5 (fig. 2) about twice as wide as long, 654 x 120u. 
Ventrally between this segment and genital segment a slight inter- 
segmental sclerite. Genital segment (fig. 2) a little longer than wide, 
1384 x 118z, in dorsal view expanded in its midregion, anterior and 
posterior to which the segment is constricted (anterior constricted 
area, set off ventrally from rest of segment by a weak transverse 
line). Areas of attachment of egg sacs situated dorsolaterally on 
posterior part of expanded area. Each area (fig. 3) with 2 naked spini- 
form setae, both about 114 in length, and a prominent unguiform 
process. Three postgenital segments 36y x 68y, 26 x 63y, and 50y x 
62u, from anterior to posterior. 
Caudal ramus (fig. 4) about as long as wide, its greatest dimensions 
being 25y x 28u when measured dorsally and 294 x 28u when measured 
ventrally. Of the usual 6 setae, outer lateral seta 48y long, pedicellate 
dorsal seta 26, outermost distal seta 734, innermost distal seta 
122u, and the 2 long median terminal setae 208» (outer) and 290p 
(inner) and both inserted between dorsal (unornamented) and ventral 
(with marginal rows of spinules) flaps. All these setae naked except
