FIGURE 5.
Hyleoglomeris wuse
sp. n.
, male paratype. A: leg 17, front view. B: leg 18, front view. C: right half of telopods, caudal view. D: apex of telopod syncoxital horn, caudal view. Scale bar: 0.2 mm (D drawn not to scale).
Diagnosis:
Differs from all congeners in the absence of a lobe on the caudomedial process of the telopod femur, of a setoid filament at the tip of the telopod syncoxital horns, coupled with a narrow, rather high, linguiform, central lobe of the telopod syncoxite, as well as a 3-segmented male telopodite 17. See also Key below.
Description:
All characters like in
H. tiani
sp. n.
, except as follows.
Length ca 6.0–
7.5 mm
(male) or 6.5–8.0 mm (female), width 3.2–4.0 mm in both sexes.
Holotype
6.0 mm long and
3.6 mm
wide. Coloration entirely pallid. Ocelli at least 4+1, translucid, mostly barely visible. Antennomere 6 ca 2.2 times as long as high.
Second tergite with 9 or 10 (usually 10) transverse striae, four starting below, one level to, the remaining striae above schism, normally seven striae (usually 1st to 3rd and 5th to 8th) from below crossing the dorsum.
Male leg 17 (
Fig. 5
A) with a rather high and regularly rounded outer coxal lobe; telopodite 3-segmented, tarsus devoid of subapical spines.
Male leg 18 (
Fig. 5
B) with a rather narrowly arch-shaped syncoxital notch; telopodite 4-segmented.
Telopods (
Fig. 5
C, D) with a high, linguiform, rather narrow, sparsely setose, central syncoxital lobe flanked by two setose horns, each latter crowned by a minute lobule (
Fig. 5
D). Prefemur and femur sparsely micropapillate laterally. Caudomedial femoral process prominent. Caudomedial process of tibia evident, membranous; tibial tubercle on caudal face distinct, papillate. Tarsus rather moderately sigmoid, rounded apically.
Remark:
Only one species of
Hyleoglomeris
,
H. eusulcata
, has hitherto been known from Guizhou Province, also a presumed troglobite from Libo County (
Golovatch et al. 2006
).
