ARANEA. O15 
with a dull pale central band. Eyes subsimilar in the two sexes, the characteristic features being more 
emphasized in the male; central quadrangle narrower behind, posterior centrals being in contact, the 
anteriors one diameter apart; both rows recurved, the anterior slightly but distinctly. Legs clothed 
with long, pale, oblique or almost erect hairs in both sexes. 
3. Coxa i. with a hook, femur ii. with a groove; coxa and femur of pedipalp with a ridge and groove 
respectively. Coxa i. with a small tubercle above. Patella of pedipalp with a single, long, curved, apical 
bristle. Femora of legs without spines beneath; i. with a pair of conspicuous, long, adjacent spines about 
the middle in front, besides other dorsal spines. Tibia ii. not incrassate, similar to tibia i., without any 
specialization of spines. Patellee with a long apical spine. Legs otherwise also numerously spined. 
Palpus. The bulb bears a long, broad, thin, curved, conspicuous conductor, apically broadened, but not 
abruptly dilate as in A. dilatata; an elongate dilate lamina, not concave on the outer side, its apex 
forming a short slightly curved point; and a short, stout, curved, serrate or cuspulate stylum. 
2. Legs spinose, with long hairs as in the ¢; femora without spines beneath. Patella with an apical bristle. 
Lower margin of fang-groove with three teeth. Sternum slightly longer than broad. 
Vulva consisting of a convex base, concave above in the middle, bearing a small elongate scapus, attenuate 
when viewed from above, but seen in profile the apex is dilate, forming a circular, oval, thin, flat plate.

The male of this spider may be distinguished from that of A. dilatata by the lamina 
of the palpal bulb being convex (not concave) and the conductor not abruptly dilate 
on the outer side at the apex. It appears to be an abundant species in Central 
America.

Very like the male of A. incerta, but with the lamina of the palpal bulb concave 
(not convex), while the conductor is abruptly dilate on the outer side near its apex.
