WOMERSLEY— MICROTROMBIDIINAE OF AUSTRALIA AND NEW GUINEA 335 

Fig. 25. Camerotrombidium rasum (Berl.) var. robensis nov. A, Crista and eyes (X 125); 
B, palp (X 200); ©, front tarsus and metatarsus (x 125); D, dorsal seta (x 860); E, seta 
from near apex and sides of propodosoma (X 860). 
Remarks. The above specimens are in complete agreement with Berlese’s 
description and figures (1912) of rasum from Germany, in the form of the dorsal 
setae and the size and dimensions of the front tarsi and metatarsi. They differ, 
however, in the presence of an external spine on the palpal tibia. Rather than 
make it a new species it is referred to varietal status.
