Viewed from above, posterior row strongly recurved, anterior row 
strongly procurved. Some irregularity in form and size of correspond- 
ing eyes has been noted among paratypes. Ratio of eyes, AME : 
ALE : PME : PLE = 1 : 10 : 5.5 : 8.5. AME darkened and dif- 
ficult to measure with accuracy; all others white. AME appear to 
be in contact medially; well separated from ALE. PME separated 
from one another by about one third of their width, from PLE by 
about their width. PLE separated from one another behind by slight- 
ly more than their length. Width of clypeus equal to one fourth of 
the long diameter of ALE. Long diameters of eyes used for meas- 
urements unless otherwise stated. 
Chelicerae. Paraxial, parallel, porrect as usual in the genus; 
fairly robust; clothed with a thick coat of stiff, procurved bristles. 
Fang long, slender, evenly curved; promargin of fang groove with 
eleven teeth, the last five considerably longer than others,, together 
with several long, slender hairs ; the retromargin has a well developed 
scopula of long, slender hairs. 
Lip and Sternum. Essentially as described for A. spinosa Pet. 
Legs. 4123. Tibial index of first leg 10; of fourth leg 12.

Spines. In general the legs are well supplied with ordinary spines; 
legs one and two with many fewer than legs three and four. 
Detailed statement of number and position of ordinary spines not 
regarded as necessary for adequate description of the species. Special 
spines at articulation of first tibia and metatarsus as shown in Figures 
2 and 3 should be noted. Numerous trichobothria have been noted 
but many are broken off from handling and the specific number and 
placements have not been determined. 
Palp. Essential features shown in Figure 4. Coxa with a rudi- 
mentary maxillary lobe bearing a chitinized ridge which, in one view, 
appears like a small tooth. 
Abdomen and Color in alcohol. Both essentially as described 
for A. spinosa Pet. 
Female allotype. Dr. Petrunkevitch (1929) gave a description 
of what was probably a mature female of this species and for this
