Posterior eyes in a straight line, the median eyes slightly larger than 

 the lateral, separated from each other by two-thirds their diameter 

 and from the lateral by one-third their diameter; anterior eyes in a 

 straight line, the median eyes smaller than the lateral and subcontigu- 

 ous while distinctly separated from the lateral. Median ocular area 

 longer than wide. Clypeus narrower than the ocular area and slightly 

 projecting. Chelicerse a little darker than the cephalothorax and some-
