mm., width 0.27 (0.28) mm. ; length of chela without pedicle 
1.38 (1.43) mm., width 0.39 (0.375) mm. ; chelal hand with- 
out pedicle 0.68 (0.7) mm. long, 0.33 mm. deep; movable 
huger 0.7 (0.75) mm. in length. Chelal teeth retroconical 
and cuspid at the distal end of the row of each finger, coni- 
cal to rounded and acuspid at the proximal end of the row ; 
fixed huger with 45 to 50 teeth, movable finger with about 
35 teeth. Movable huger with one tactile seta, hxed huger 
with seven ; setae distributed as indicated in hgure 14. 
Legs as in the subgenus Synsphyronus except that the 
tarsus of one or more legs may have a suture dividing the 
tarsus into two parts, which, however, are never articu- 
late; incompletely fused metatarsus and telotarsus may 
occur on the same animal as has some of the tarsal podo- 
meres completely fused; tarsal claws stout; pedal chaeto- 
taxy much as in S. niger described above. First leg fairly 
stout; trochanter 0.235 mm. long, 0.16 mm. deep; pars 
basalis with extensor margin nearly straight, flexor mar- 
gin weakly convex, length 0.26 mm., depth 0.135 mm. ; pars 
tibialis with extensor margin nearly straight except near 
the proximal end in the holotype but somewhat evenly 
convex in the paratype, flexor margin moderately convex, 
length 0.25 mm., depth 0.16 mm. ; tibia with extensor mar- 
gin nearly straight, length 0.31 mm., depth 0.105 mm. ; 
miotarsus (fused metatarsus and telotarsus) 0.285 (0.305) 
mm. long, 0.08 mm. deep. Fourth leg relatively slender; 
trochanter about 0.34 mm. long (broken in holotype and 
length not determined), 0.16 (0.17) mm. deep ; pars basalis 
with a slight protuberance at the distal end of the nearly 
straight flexor margin, 0.275 mm. long, 0.16 mm. deep; 
pars tibialis with extensor margin a little flatly convex 
except at the ends, flexor margin nearly straight, length 
0.55 (0.54) nun., depth 0.19 (0.185) mm. ; entire femur 0.75 
(0.74) mm. long; tibia weakly S-shaped, length 0.52 mm., 
depth 0.115 (0.11) mm.; miotarsus subcvlindrical or a 
little fusiform, 0.38 (0.39) mm. long, 0.095 (0.09) mm. 
deep. 
Genital complex simple, anterior operculum with six 
setae, posterior operculum with six (paratype) or eight 
(holotype) setae; two median cribiform plates, arranged
