Allied to ZV. ovifer. Represented only by small specimens which differ 
from specimens of JV. ovifer of equal size. The anterior margin outside 
the orbital fissure is fur- 9 
nished with two spines 
close together, instead of 3 
one in the allied species. 
The eyes are smaller than in WV. ovifer, 
but have a prominent tubercle. The 
spine of the antennal scale extends only 
slightly beyond the blade. The hands ) "Shon séeq “a Dorsal view of cata
