Rarahu nitida Berland 
This genus and species were described by 
Berland (1929) from a single male from Ma- 
lololelei, Upolu, Samoa. In the Otago Museum 
collection are four females and one male col- 
lected from moss in the rain forest at Afiamalu, 
very close to Malololelei. The male is smaller 
than Berland’s specimen and differs in color and 
in slight details, but it seems to belong to the 
same species. Its measurements and brief de- 
scription are given here for comparison with 
those of the female. 
MALE: Length 1.90 mm. General color pale 
brown, the margin of the carapace dark, the 
ocular area almost black, the abdomen with a 
broad anterior transverse band followed by four 
narrow ones. This differs from Berland’s speci- 
men, which was dark brown with lighter parts 
on the legs. 
Carapace: Length 1.02 mm, breadth 0.63 mm. 
Eyes: Ratios of the diameters of the eyes and 
of their distances apart: AM, 118; AL, 61; PM, 
27; PL, 71; AL-PM, 100; PM-PL, 92; PM-PL, 
273. Anterior eyes in contact, row strongly 
recurved. This is essentially as described by 
Berland. 
Palp: As in Figure 7 and as figured by 
Berland.
