Pacific Island Spiders, V — Marples 
lateral teeth opposite to them, the one nearest 
the fang being the largest. A sharp retrolateral 
tooth close to the base of the fang. 
Maxillae: Rounded and expanded distally, the 
median corner truncated. 
Lip: Slightly more than half the length of the 
maxillae. Concave distally. 
Sternum: Length 1.37 mm, breadth 0.94 mm. 
Convex. 
Palp: Spines: femur, one dorsal and four 
distal; patella, three dorsal; tibia, two pairs 
prolateral-dorsal. Tibia with a long slender re- 
troiateral apophysis, about half the length of the 
tarsus, with a short one ventral to its base.

Scopulae on tarsi, metatarsi and very slightly on 
tibiae I and II. Legs I and II have two pairs of 
spines on the tibiae, and three dorsal and one 
prolateral-distal spine on the femora. 
Abdomen: Length 2.94 mm, breadth 1.37 
mm. Stout bristles anterodorsally and a few 
above the spinnerets. 
Differs from C. alveolata in the large tibial 
apophysis on the palp and the absence of hairs 
on the chelicerae. The ridge on the chelicerae 
is much smaller and more oblique than that of 
C. samoensis, whose chelicerae are also hairy. 
SALTICIDAE 
Flacilla kraussi n. sp. 
MALE: Aitutaki. Collected by N. L. H. Krauss 
in I960. Length 4.79 mm. Carapace brown, 
darker round the edge and especially in the

lateral views of male palp. 
ocular area where the eyes are surrounded by 
black. Chelicerae, maxillae, lip, and legs I, dark 
brown. Palps, remaining legs, sternum, and ab- 
domen pale brown. The dorsal surface of the 
abdomen with a darker ill-defined pattern con- 
sisting of a dark mark over the heart, anterior 
dorsolateral patches and posteriorly three trans- 
verse bands somewhat interrupted and irregular 
near the middle line. 
Carapace: Length 1.95 mm, breadth 1.37 mm. 
Flat and rectangular in appearance. Anteriorly 
directed hairs around the eyes and flattened 
pale ones within the ocular quadrangle. 
Eyes: Anterior row recurved. Ratios of the 
diameters of the eyes and of their distances 
apart: AM, 157; AL, 62; PM, 40; PL, 74; AM- 
AM, 18; AM-AL, 39; AL-PM, 126; PM-PL, 
102; PL-PL, 445. AM in contact with the mar- 
gin of the carapace. Ratios of the dimensions 
of the ocular quadrangle, including the eyes: 
AL-AL, 517; AL-PL, 388; PL-PL, 545. 
Chelicerae: Small, with oblique groove. On 
the ventral promargin are two teeth, the one 
nearer to the fang being the larger. One retro- 
marginal tooth opposite to this and of equal 
size. 
Maxillae: Long. 
Lip: More than half the length of the maxil- 
lae, narrow, rounded anteriorly. 
Sternum: Length 0.95 mm, breadth 0.55 mm. 
Convex, narrow anteriorly between the large 
coxae I and with a slender posterior point be- 
tween coxae IV. 
Palp: Well-developed tibial apophysis. As in 
Figure 5.
