Etymology.
The specific epithet refers to the Kingdom of
Abkhazia
, which was also known as Abasgia or Egrisi-Abkhazia. It was a medieval feudal state established in the Caucasus in the 780s.
Diagnosis.
The new species is most similar to the species that has been identified and illustrated as
H
.
caucasia
by
Dunin (1992b)
in the shape of the copulatory organs. The male can be distinguished by thinner bulb (ca. 1.3 times longer than wide,
vs
. about as long as wide), shape of embolus base (presence of a kind of a heel (
EH
),
vs
. absent), and shorter and heavily sclerotized ‘conductor’ (
Co
) directed posteriorly (
vs
. membranous ‘conductor’ directed laterally) (cf.
Fig. 15A 15J
). The female differs by the widened and abrupt tip of receptacle (
vs
. rounded and slightly tapering), and by the claw-like lateral margins (
LMA
) of anterior arch (
vs
. rounded) (cf.
Fig. 16
and
Dunin 1992b
: fig.
14г
). From the
holotype
of
H
.
caucasia
, the new species differs by having an embolic base heel (
vs
. absent) and shorter proximal outgrowth of the conductor (cf.
Fig. 15A, B and D, E, H, I
). The two species also differ by the relative length of legs (leg I/carapace length ratio: 2.5
vs
. 3.53).

Bulb as in
Fig. 15A–C
; ca. 1.3 times longer than wide, ‘conductor’ (
Co
) with subtriangular membranous base and well sclerotized digitiform extension directed anteriorly; embolus bent at base at ca. right angle, terminal part bent on acute angle, proximal part of embolus with kind of heel (
EH
).
Female. Habitus as in
Fig. 14B
. Total length 4.20. Carapace 1.83 long, 1.45 wide. Eye sizes: AE 0.10, PME 0.09, PLE 0.10. Coloration as in male. Measurements of legs: I: 4.94 (1.36, 0.94, 1.15, 1.06, 0.43), II: 4.54 (1.21, 0.80, 1.11, 1.00, 0.42), III: 3.85 (1.04, 0.57, 0.81, 1.00, 0.43), IV: 5.60 (1.57, 0.80, 1.30, 1.45, 0.48). Spination: I: Fe: 2pl. II: Fe: 2pl. III: Fe: 1d, 2pl; Pa: 1pl; Ti: 1d, 3pl, 2rl, 4v; Mt: 3pl, 2rl, 2v. IV: Fe: 3d; Ti: 1d, 3pl, 3rl, 5v; Mt: 2d, 3pl, 3rl, 3v.
Endogyne as in
Fig. 16
; with long receptacle (
Re
) slightly longer than anterior arch (
AA
), tip slightly widened and abrupt at the top edge, lacking bulbous widening; anterior arch with claw-like lateral margins (
LMA
) directed meso-anteriorly.

Comments.
We had the opportunity to examine photographs of the
holotype
male of
H
.
caucasia
and compare them with our new species. Although
Brignoli (1980)
mentioned that he had studied this material, his figures of the male palp are similar to those in
Dunin (1992b)
and yet different from the
holotype
(cf.
Fig. 15J and D, H, I
). It is not clear what specimens were erroneously illustrated as
H
.
caucasia
by these authors, but they seem to represent an undescribed species. Most likely, all records of
H
.
caucasia
from
Abkhazia
and probably Northern Caucasus are based on misidentified specimens of
H
.
abasgiana
sp. n.
