males, 4 males. Vava'u. 1 Female. Ononua, 
Ha'apai. This species was described from 
Samoa, where it is very variable in colour, be- 
ing frequently without the dark markings. 
The very similar D. septempunctata was de- 
scribed by Koch from Tonga. The present 
specimens are pale, or sometimes with three 
pairs of small spots, but their reproductive 
organs resemble those of specimens from 
Samoa and they seem to belong to this species. 
SALTICIDAE 
Ascyltus pterygodes (L. Koch) 
3 Females, 3 males, 14 imm. Tongatabu. 
1 Male, 2 imm. Eua Island, Ha'apai. 7 Fe- 
males, 5 males, 24 imm. Vava'u. Widespread 
species, not previously recorded from Vava'u. 
Claws: Two, pectinated about 12. Tenent 
hairs in dense tufts on the feet and extending 
along the ventral surface of each tarsus and 
metatarsus, and sparsely on tibiae I and II. 
Spines: I. One pair at the proximal end of 
the tibia. 11. None. III. One retrolateral- distal 
on the tibia; 2 median and 4 distal on the 
metatarsus. IV. One retrolateral- distal on the 
tibia; 1 ventral-proximal, 2 median and 4 
distal on the metatarsus. 
Abdomen: Length 4.33 mm., breadth 2.48 
mm. Epigynum as in figure. 
Clubiona alveolata L. Koch 
1 Female. Nuku'alofa, Tongatabu. 1 Male. 
Neiafu, Vava'u. Several immature specimens 
which may belong to this species, which is 
widespread in the Pacific but not previously 
recorded from Tonga. 
SPARASSIDAE 
Heteropoda venatoria (Linn.) 
1 Female. Tongatabu. 1 Female, 2 males. 
Vava'u. 
THOMISIDAE 
Diaea praetexta L. Koch 
4 Eemales. Nuku'alofa, Tongatabu. 17 Fe- 
Bavia aericeps Simon 
1 Male, 3 imm. Tongatabu. 1 imm. Vava'u. 
First records for the Tonga group. A wide- 
spread species. 
Erasmia nigrovittata Keyserling 
1 Female. Vava'u. This species was described 
from a single female from Tonga. Keyserling 
does not mention the cheliceral teeth, but 
Berland (1934) places the species amongst the 
Fissidentati. Petrunkevitch (1928) lists it as a 
synonym of Iona Peckham, one of the uni- 
dentate species. The present specimen agrees 
well with Keyserling’s description, and has 
four distinct teeth on each of the margins of 
the cheliceral groove. 
Menemerus bivittatus Dufour 
1 Female. Nuku'alofa, Tongatabu. 
Mollicia microphthalma L. Koch 
1 Female, 2 imm. Tongatabu. 1 Female. 
Panga, Ha'apai. 1 Male. Holonga, Vava'u. 
A widespread species, first records for the 
Tonga group. 
Plexippus payculli Auduin 
1 Female. Vava'u. A widespread species, first 
record for Tonga.
