VARIABILITY: This species shows some variability in certain genital structures, such as size of the rounded swelling on the paracymbium, and shape and density of the fringed margin of the embolus (see
Tanasevitch & Saaristo, 2006
). Nevertheless the shape of the distal part of the lamella characteristica is consistent enough and is a good, well-visible character to distinguish this species.
REMARKS:
A. nepalensis
was previously known from numerous localities in
Nepal
(
Tanasevitch, 1987
;
Tanasevitch & Saaristo, 2006
). The species is here recorded from
Pakistan
and
India
for the first time.
RANGE: Himalayan.

ETYMOLOGY: The species name, an adjective, points out the similarity of the new species and
A. nepalensis
(
Tanasevitch, 1987
)
.
DIAGNOSIS: The new species is characterized by the peculiar shape of the lamella characteristica.
DESCRIPTION: Male. Total length 2.20. Carapace 0.98 long, 0.83 wide, pale brown, almost yellow, with a greyish margin. Chelicerae 0.43 long. Legs yellow. Legs or its distal segments mostly lost, FeI & II 1.23 long. Chaetotaxy unclear, but probably equal to that of
A. nepalensis
, i.e. Fe I: 0-1-0-0: Ti I: 2-1-1-0, II: 2-0-1-0, III-IV: 2-0-0-0; Mt I-III: 1-0-0-0. TmII 0.11. Metatarsus IV without trichobothrium. Palp (Figs 26-31): Tibia flattened distally. Cymbium with a small posterodorsal conical tubercle. Paracymbium with a rounded swelling in mesal part. Distal part of lamella characteristica fork-shaped, upper branch twice longer than lower one, with a small tooth between both branches. Upper edge of lamella characteristica carrying a spear-shaped outgrowth directed backward. Embolus fringed at margin. Abdomen 1.18 long, 0.88 wide, pale grey.
Female unknown.
TAXONOMIC REMARKS: The new species is very similar to
A. nepalensis
, but can be easily distinguished by the shape of the distal part of the lamella characteristica. See also above, under Remarks to
A. nepalensis
.
DISTRIBUTION: Known from the
type
locality only.
