Coxae of pedipalps with numerous cuspules along the inner or 

 anteromesal side as usual. 



Posterior claw of all legs armed with a tooth at base, but that on 

 claw of leg IV sometimes almost obliterated, that on other legs moder- 

 ately large. Anterior claw unarmed or with a very small tooth near 

 base. Leg I with 7 or 8 spines on anterior side of tibia and a band of 

 numerous, mostly larger, spines on the posterior side, no spines on 

 ventral surface of this joint; tarsus and metatarsus armed as usual. 

 Leg II with tibia unarmed on the anterior side or ventrally, but with 

 numerous short spines over entire posterior side as usual; metatarsus 

 and tarsus as usual. Leg III with patella bearing 8 stout tooth-like 

 spines in a series along distal margin dorsocaudally and a few proxi- 

 mad of this series, and on the anterior side a similar series also of about 

 eight spines with proximad of it a rather irregular patch of about 

 as many more; tibia with a similar series of spines on the distal margin 

 on the caudal side, while on the anterior side the spines are more 

 numerous than on the patella and the spinous area extends from the 

 distal end proximad of middle of length; metatarsus dorsally with a 

 longitudinal series of spines toward anterior side and with two or 

 three series on the caudal side, some of the latter being strictly lateral, 

 ventrally unarmed excepting for the pair of spines at distal end; 

 tarsus with many spines over lateral surface and also ventrally; 

 patella of third legs much longer than the tibia and the tibia wider 

 than long. Leg IV with patella bearing many spines on anterior 

 side over entire length, but with none at all on posterior side; tibia 

 wholly unarmed; metatarsus unarmed ventrally excepting at distal 

 end, on anterior side with about 8 spines in an irregularly double 

 series extending from a point part way between base and middle to 

 the distal end; tarsus with many spines beneath and especially on 

 the anterior side.

This species agrees with A. caraiba Simon in having the first row of 

 eyes longer than the second, but the difference is more decided; from 

 the latter species it also differs in having the posterior median eyes
