Aphorura lutea n. sp. 
In general appearance this species is the same as the 
Aphorura montis except that it is yellow in color. The size 
and shape of the body are about the same. The claws, and 
number of anal horns and ocelliform punctures are the same. 
The most important differences are in the color and in the 
postantennal organ. It contains only nine tubercles, five on the 
antennal side and four on the other, instead of eleven as in 
montis. Although the antenne varied in the different speci- 
mens, two rows of blunt spines were found on the third seg- 
ment. One row was found on those of the white species.
