Abdomen elongate with sides weakly and evenly con- 
vex, length 1.9 mm., width 1.05 mm. All tergites equally 
sclerotic, not divided, surface marked by very faint net- 
like sculpturing*. Each of the first two tergites with four 
setae, more posterior tergites with six setae, the tenth and 
the eleventh with 10 setae. St emit es a little more lightly 
pigmented than the tergites and virtually unsculptured. 
Most sternites with six to 10 very fine acuminate setae ; 
sternites not divided. 
Chelicera fairly stout, 0.27 mm. long, width of base 
0.16 mm. Flagellum of three setae, anterior one stout 
and denticulate along the distal one-third ; the middle seta 
about two-thirds the length of the distal one and also sub- 
terminally denticulate ; the proximal seta inconspicuous, 
less than one-half the length of the middle one, and ap- 
parently acuminate. Fixed finger gently curved, with 
four or five small, retroconical teeth along the distal one- 
half of the inner margin; lamina exterior wide and con- 
spicuous ; distal tooth of serrula interior ligulate and with 
finely serrate margin, next three more proximal teeth 
platyform and with serrate margins, other teeth modified 
to form a velum. Movable cheliceral finger a little 
curved, fairly slender; serrula exterior of 20 ligulate 
plates ; subapical lobe stout and with two rounded cusps ; 
apical tooth no more sclerotic than the rest of the finger ; 
galeal seta inserted near the base of the subapical lobe 
and not reaching to the tip of the galea; galea (Fig. 1) 
stout, straight, and with three fairly stout and little- 
curved terminal and subterminal rami ; length of movable 
finger 0.2 mm. 
Palps (Fig. 2) moderately stout; polished reddish 
brown in color; investing setae long, acuminate, and fairly 
numerous ; surface smooth except for weakly developed 
granules on the sides of the maxillae, on the trochanteral 
protuberances, on the central portion of the flexor surface 
of the femur, and along the distal half of the flexor surface 
of the chelal hand. Maxilla 0.44 mm. long, 0.28 mm. wide ; 
trochanter 0.40 mm. long, 0.24 mm. wide; femur 0.71 mm. 
long, width 0.26 mm. ; tibia 0.71 mm. long, 0.31 mm. wide ; 
chela without pedicle 1.16 mm. long, 0.44 mm. wide ; chelal
