Material examined:
Holotype

Paratypes
.
1 female
(
IZAS
),
1 male
,
1 female
(
MNHN
CC 180), same locality, together with
holotype
.
Name:
To emphasize the presence of a rather short transverse sulcus on the second tergite.
Diagnosis:
Differs from congeners except
H. eusulcata
and
H. speophila
Golovatch, Geoffroy & Mauriès, 2006
, from
Laos
(
Golovatch et al. 2006
), by the presence of a transverse sulcus above the schism on the second tergite (yet shorter, reaching only ca 1/5 height of the second tergite), from
H. speophila
by the presence of only one complete stria on the collum and of a lobe on the caudomedial process of the telopod femur, from
H. eusulcata
by the absence of a setoid filament at the tip of the syncoxital horns. See also Key below.
Description:
All characters like in
H. tiani
sp. n.
, except as follows.
Length ca 6.0 (
paratype
) to
7.5 mm
(
holotype
) in male, 7.5–8.0 mm in female; width 3.7 (
holotype
) or
3.8 mm
(
paratype
) in male, 3.9 or
4.5 mm
in female. Coloration entirely pallid.
Ocelli at least 3+1, translucid, barely visible. Antennomere 6 ca 2.1 times as long as high.
Collum with one transverse stria. Second tergite with six transverse striae, two starting below, one level to, the remaining striae above schism, 3 or 4 striae (not last two ones from below, both forming a rather short, but evident transverse sulcus above schism) crossing the dorsum.
Male leg 17 (
Fig. 16
A) with a rather low and irregularly shaped outer coxal lobe; telopodite 3-segmented, tarsus with two subapical spines.
Male leg 18 (
Fig. 16
B) with an arch-shaped syncoxital notch; telopodite 4-segmented.
Telopods (
Fig. 16
C–E) with a linguiform, sparsely setose, central syncoxital lobe flanked by two setose horns, each latter crowned by an inconspicuous lobule (
Fig. 16
E). Both prefemur and, to a lesser extent, femur micropapillate laterally. Caudomedial femoral process prominent, subapically with a distinct lateral lobe on caudal face (
Fig. 16
D). Caudomedial process of tibia evident, membranous; tibial tubercle on caudal face distinct, non-papillate. Tarsus rather evidently sigmoid, narrowly rounded apically.
Remark:
Due to its troglomorphic traits, this species is likely to represent a troglobite.
