Etymology.
The species name is derived from the
type
locality; adjective.
Diagnosis.
The new species is similar to
A. proxima
(O.
Pickard-Cambridge, 1871
)
, but the male can be distinguished by: 1) the membranous, narrow base of the median apophysis (
vs
sclerotized and wide); 2) the long RTA (
vs
short); and 3) the downward bending conductor (
vs
upward). The female can be distinguished from
A. proxima
by: 1) the wide septum (
vs
narrow); 2) the presence of two hoods on anterior septum (
vs
without hoods); and 3) the direction of the large copulatory openings, which are directed obliquely upwards.

Sternum yellow, margin fuscous, longer than wide. Legs fuscous; tibia I with 3 pairs of ventral spines, tibia II ventral with one prolateral spine and three retrolateral spines. Metatarsi I and II with two pairs of ventral spines. Measurements of legs: leg I 3.74 (1.03+0.54+0.91+0.73+0.53), leg II 3.43 (0.94+0.52+0.78+0.68+0.51), leg III 3.28 (0.88+0.49+0.63+0.78+0. 50), leg IV 4.73 (1.19+0.56+1.04+1.30+0.64).
Palp (
