Etymology. The species name comes from the Latin word ‘semiorbiculatus’, in reference to hemispherical apex of the distal part of the scape.

Diagnosis. The female A. semiorbiculatus n. sp. can be distinguished from A. arcuatulus and A. cruciatus n. sp., by the epigynum triangular in ventral view ( Fig. 3G View FIGURE 3 ) and bulged in lateral view ( Fig. 3H View FIGURE 3 ), the U-shaped scape more expanded than the other two species, and by the distal part of scape having the two lateral lobes fused into a hemisphere shape ( Fig. 3I View FIGURE 3 ). Male unknown.

Description. Female (AMNH-158): Total length 1.59. Carapace 0.76 long, 0.55 wide. Abdomen 0.92 long, 0.63 wide. Leg lengths: I 2.95 (0.82+1.02+0.69+0.42); II 3.01 (0.83+1.03+0.71+0.44); III 2.63 (0.66+0.98+0.61+0.38); IV 3.38 (0.98+1.11+0.85+0.44). Tm I 0.23. Male unknown.
