Fig. 3. Clubiona upoluensis. Ventral and retrolateral 
"views of the male palp. 
and metatarsi with a single dorsal row of tricho- 
bothria increasing in length distally. 
Abdomen: Length 1.78 mm, breadth 1.19 mm. 
Colulus a broad lobe. Anterior spinnerets narrow 
and cylindrical, posterior spinnerets conspicu- 
ously long and slender, twice the length of the 
anterior ones. 
CLUBIONIDAE 
Clubiona upoluensis n. sp. 
MALE: Collected by E. C. Zimmerman at 
Afiamalu, Upolu, Samoa, vii-3-40. Length 8.04 
mm. Pale brown all over, carapace slightly 
darker. 
Carapace: Length 333 mm, breadth 2.40 mm. 
Smooth oval. 
Eyes: Eight, posterior row straight, anterior 
row slightly recurved. Ratios of the diameters 
of the eyes and of their distances apart: AM, 
161; AL, 221; PM, 173; PL, 200; AM-AM, 222; 
AM-AL, 178; AM-PM, 218; PM-PM, 435; 
PM-PL, 342; L-L, 160; clypeus, 95. Breadth of 
eye-group, 1.15 mm. 
Chelicerae: Promargin of the groove with 
three teeth, the smallest nearest the fang, the 
largest in the middle, the third prolonged proxi- 
mally as a ridge. Retromargin with two small 
teeth, one opposite the small promarginal one, 
the other nearer to the fang. 
Maxillae: Long, constricted in the middle, 
wide and rounded distally. 
Lip: Little more than half the length of the 
maxillae. 
Sternum: Length 1.59 mm, breadth 1.08 mm. 
Smoothly oval with a broad concavity anteriorly. 
Palp: As in Figure 3.

Metatarsi I and II with one proximal pair of 
spines, tibiae I and II with two pairs of spines 
and one prolateral-distal spine. Metatarsi and 
tibiae III and IV with numerous spines, and all 
femora with spines. Tarsi and metatarsi I and II 
with scopulae, also a very slight one on tibia I. 
Abdomen: Length 4.51 mm, breadth 1.96 
mm. Spinnerets long, anterior pair much the 
stoutest. 
A larger and more slender spider than C. 
alveolata, considerably larger than C. samoensis, 
as well as differing in details. 
Clubiona zimmermani n. sp. 
MALE: Collected by E. C. Zimmerman at 
Fagatogo, Tutuila, Samoa, at 900', viii— 2 5—40. 
Length 5.49 mm. Pale brown, carapace and 
mouthparts slightly darker. 
Carapace: Length 2.60 mm, breadth 1.86 mm. 
Smoothly oval. One spine above PME and ALE, 
two above PLE. 
Eyes : Posterior row straight, anterior row 
very slightly recurved. Ratios of the diameters 
of the eyes and of their distances apart: AM, 
192; AL, 188; PM, 167; PL, 187; AM-AM, 173; 
AM-AL, 119; AM-PM, 139; PM-PM, 400; 
PM-PL, 277; L-L, 108; clypeus, 80. Breadth of 
eye-group 1.01 mm. 
Chelicerae: Smooth and tapering. A low but 
distinct ridge runs proximally from the pro- 
lateral side of the base of the fang. Groove 
oblique, three prolateral teeth at the ventral 
end, the middle one the largest. Three retro-
