This is a low, flat, slender spider. The quadrangle of the 

 eyes is one-third wider than long, slightly wider behind than 

 in front, and occupies about two-fifths of the cephalothorax. 

 The eyes of the first row are close together, in a straight line, 

 the middle being nearly twice as large as the lateral. The 

 second row is half-way between the first and third rows. The 

 third row is nearly as wide as the cephalothorax at that place. 

 The sides of the cephalothorax are nearly parallel. The cepha- 

 lic and thoracic parts are on the same plane and are very flat 

 above. The first legs are short, with the femur and tibia 

 heavily thickened, giving a short, stubby look. 



The cephalothorax and abdomen are black, nearly covered 

 with white hairs. In the posterior half of the abdomen are 

 first, a pair of round spots, next a pair of spots somewhat 

 lengthened out, and finally, in front of the spinnerets, a pair of 

 curved bands, all in bright yellow. The male has the legs and 

 palpi brown, with white hairs, the first pair darker than the 

 others. The female has the legs and palpi light reddish-yel- 

 low, the palpi being covered with white hairs. The clypeus is 

 covered with white hairs. The falces are dark brown. 



Central America (exact locality unknown).
