Name.
To emphasize the animal’s provenance from Cave Mashan Dong in Mulun Karst.
Diagnosis:
Differs from congeners except
H. eusulcata
,
H. curtisulcata
sp. n.
and
H. yinshi
sp. n.
in the presence of only one complete transverse stria on the collum, from both
H. eusulcata
and
H. curticulcata
sp. n.
by the absence of a transverse sulcus on the second tergite, from
H. yinshi
sp. n.
by the shape of the central lobe of the telopod syncoxite and of the notch in male syncoxite 18. See also Key below.
Description:
All characters like in
H. tiani
sp. n.
, except as follows.
Length ca
7.5 mm
, width
3.7 mm
. Coloration entirely pallid.
Ocelli at least 3+1, translucid, barely visible. Antennomere 6 ca 2.2 times as long as high.
Collum with one complete transverse stria. Second tergite with eight transverse striae, three starting below, one level to, the remaining striae above schism, four striae (not last two ones from below) crossing the dorsum.
Leg 17 (
Fig. 15
A) with a low and irregularly shaped outer coxal lobe; telopodite 4-segmented, tarsus devoid of subapical spines.
Leg 18 (
Fig. 15
B) with a narrowly arch-shaped syncoxital notch; telopodite 4-segmented.
Telopods (
Fig. 15
C, D) with a rather low, linguiform, sparsely setose, central syncoxital lobe flanked by two setose horns, each latter crowned by a highly inconspicuous lobule (
Fig. 15
D). Both prefemur and, to a lesser extent, femur micropapillate laterally. Caudomedial femoral process prominent, subapically with a distinct lateral lobe on caudal face. Caudomedial process of tibia evident, membranous; tibial tubercle on caudal face distinct, papillate. Tarsus evidently sigmoid, subacuminate apically.
Remark:
Due to several troglomorphic traits, this species seems to be a troglobite.
