The male and female Habronattus pretiosus have sev- 
eral characters in common as do several other species of 
the genus. Both have the eye area covered with scales, 
white in the male and golden in the female ; the legs 
have the same dark ventral spots on the femora but only 
the male has the prolateral surface of the first femur flat- 
tened and covered with white scales. The lateral stripes 
of iridescent scales on the cephalothorax that end 
abruptly on the posterior slope are very conspicuous and 
are common to both male and female. The flattened area 
on the first femur of the male has not been seen before 
in the genus and is very conspicuous.
