[Mar- 
hand without pedicle 0.60 mm. long, 0.42 mm. deep. From 
the side, chelal hand (Fig. 3) stout, depth little less than 
the width ; hand not much narrowed towards the fingers ; 
length of movable finger 0.62 mm. Many marginal teeth 
of chelal fingers broken hut apparently about 45 conical 
and cuspid teeth distributed along nearly the entire mar- 
gin of each finger. 
Legs moderately stout, yellow in color; setae fine and 
acuminate, sparse on the proximal podomeres but longer 
and more numerous on the distal podomeres ; surfaces of 
pedal podomeres apparently unsculptured ; tarsal claws 
stout. First leg with pars basalis deepest across the dis- 
tal end, length measured along the extensor margin 0.264 
mm., depth 0.13 mm. ; pars tibialis stout, extensor margin 
flatly convex, flexor margin more convex, length measured 
along the extensor margin 0.22 mm., depth 0.143 mm. ; 
tibia subcylindrical except in the proximal portion, length 
0.30 mm., depth 0.103 mm. ; metatarsus subcylindrical, 
length 0.135 mm., depth 0.07 mm. ; telotarsus a little deeper 
proximally than distally, length 0.133 mm., depth 0.067 
mm. Fourth leg with extensor margin of femur a little 
flatly convex in the center, more convex near the ends; 
flexor margin of femur more weakly and evenly convex 
than the extensor margin; length of pars basalis 0.23 
mm. ; length of pars tibialis measured along the extensor 
margin 0.55 mm., depth 0.265 mm. ; length of entire femur 
0.67 mm.; tibia with extensor margin nearly straight 
except at the proximal end, flexor margin weakly convex, 
length 0.50 mm., depth 0.14 mm. ; metatarsus subcylindri- 
cal, with a long tactile seta inserted very close to the 
proximal margin, length 0.20 mm., depth 0.095 mm. ; telo- 
tarsus subcylindrical, length 0.17 mm., depth 0.078 mm. 
Genital complex very simple ; posterior operculum or 
third sternite with four setae. One median and two lateral 
cribiform plates, all small and subequal in size. 
Type locality. The female holotype collected by Mr. 
G. Archey on Tera Kihi Island, Hauraki Gulf, New Zea- 
land, on October 25, 1924.
