Pacific Island Spiders — MARPLES 
75 
tooth at the ventral end. This has four serra- 
tions on its ventral side and a high, slightly 
bifurcate tip. The basal half of the fang is 
stout, the distal part more slender and taper- 
ing. At the point of transition there is some- 
thing of a flange which bites into the concavity 
on the retromargin of the groove, and a blunt 
elevation on the prolateral side. 
Maxillae: Parallel and elongate. On the 
ventral surface the central third is a longitu- 
dinal elevation with distinct margins. On the 
median side of the elevation there is a shelf 
overlapped by the lip and distal to this occu- 
pied by a scopola; on the lateral side there is 
a large hemispherical pit with dark walls and 
margin. 
Lip: Longer than broad, truncated distally. 
Sternum: Length 1.55 mm., breadth 0.98 
mm. Convex, not indented opposite the coxae. 
Palp: Unusually long and leg-like with 
small bulb. At the centre of the ventral side 
of the femur is a stout hook curved distally, 
two distal spines on dorsal side (Fig. 2).

Spines: Metatarsus; I and II, two pairs ven-

tral and one proximal prolateral, IV, three 
distal. Tibia; I, three ventral pairs, II, two

and one each pro and retro, IV, two distal 
and one proximal ventral, one pro- and two 
retrolateral. Femur; I and II, one pair distal

three distal and dorsal and two single dorsal. 
Abdomen: Length 4.18 mm., breadth 2.41

The generic allocation of this species is 
doubtful, but it seems to resemble T. gracili- 
palpis Berland (1929) in many ways. It differs 
in the palps and the teeth on the chelicerae. 
LYCOSIDAE 
Lycosa tongatabuensis Strand 
1 $ , 1 cf • Pukapuka. Though smaller and paler 
than specimens from Samoa, they seem to 
belong to this species. According to Berland, 
it is widespread, occurring also in Tonga, 
Tahiti, and the Tuamotus. 
Lycosa sp. 
1 $ . Tongatabu. This seems to be a different 
species with pale carapace, abdomen without 
pattern and legs not ringed. Legs long, espe- 
cially IV. Epigynum very small. It does not 
seem desirable to describe this as a new spe- 
cies without comparative material, as many 
of the Lycosidae are not adequately described. 
THERIDIIDAE 
Conopistha samoensis (L. Koch) 
2 $ and 1 imm., 2c ? and 1 imm. Tongatabu. 
on webs of Nephila. The species was described 
from Samoa and has been recorded also from 
New Caledonia, New Hebrides, and Tahiti. 
As in some of the Samoan specimens the dark 
band up the side of the abdomen is absent. 
The male is smaller than that from Samoa 
and the profile is slightly different, the eye- 
bearing projection being closer to the anterior 
one, but the palp is the same in each. 
Conopistha unimaculata Marples 
2$ imm., Id. Tongatabu. The species was 
described from Samoa. A single incomplete 
female from Niue is much larger, but resem- 
bles this species and may belong to it.
