Hyleoglomeris heshang
sp. n.
, male paratype. A: leg 17, front view. B: leg 18, front view. C & D: left half of telopods, caudal and front views, respectively. E: tip of syncoxital horn, front view. Scale bar: 0.2 mm (E drawn not to scale).
Diagnosis:
Differs in its residual coloration of a few ocelli, as well as by the roundly subtriangular central lobe of the telopod syncoxite, the presence of a distinct chitinized lobe from the telopod caudomedial femoral process, and the absence of a setoid filament at the tip of the telopod syncoxital horns. See also Key below.
Description:
All characters like in
H. tiani
sp. n.
, except as follows.
Length ca 5.5–6.0 mm, width 2.5–3.0 mm in both sexes.
Holotype
6.0 mm long, 3.0 mm wide. Coloration entirely pallid to sometimes very faintly yellowish, 2 or 3 uppermost ocelli sometimes faintly brownish.
Ocelli 5+1 or 6+1, translucid, often barely visible. Antennomere 6 ca 1.7–1.8 times as long as high.
Second tergite with 8 or 9 transverse striae, three starting below, 1 or 2 level to, the remaining striae above schism, 5 or 6 striae (neither 1st nor last from below) crossing the dorsum.
Male leg 17 (
Fig. 12
A) with a high and rather regularly rounded outer coxal lobe; telopodite 4-segmented, tarsus with two subapical spines.
Male leg 18 (
Fig. 12
B) with a narrowly arch-shaped syncoxital notch; telopodite 4-segmented.
Telopods (
Fig. 12
C–E) with a rather low, roundly subtriangular, sparsely setose, central syncoxital lobe flanked by two setose horns, each latter crowned by a minute lobule (
Fig. 12
E). Caudomedial femoral process prominent, subapically with a distinct lateral lobe on caudal face. A caudomedial process of tibia absent; tibial tubercle on caudal face evident, papillate. Tarsus rather strongly sigmoid, subacuminate apically.
Remark:
Due to its troglomorphic traits, this species might well prove to be a troglobite.
