Description
Hyleoglomeris youhao sp. n.
Fig. 3.
Material examined: Holotype male (IZAS), China, Hunan Prov., Linwu County, Sanhe Town, near Changshali Village, Cave 2, 19.06.2009, leg. Tian Mingyi & Xue Zhihong (8,12♀ CHIhn09–LWX03). Paratypes. 1 male, 2 females (IZAS), 2 males, 2 females (SCAU), 2 males, 4 females (MNHN CC 170), 1 male, 2 females (ZMUM), 1 male, 2 females (GNUG), same locality, together with holotype.
Name: To emphasize the type series being large enough to share with all of the relevant repositories, “ youhao ” in Chinese meaning “friendly”; a noun in apposition.
Diagnosis: Differs by the residual coloration on the head, by the presence of a lobe on the caudomedial process of the telopod femur, coupled with a subquadrate, slightly concave, central lobe of the telopod syncoxite. See also Key below.
Description: All characters like in H. tiani sp. n., except as follows.
Length ca 6.0–8.0 mm, width 2.8–3.7 mm in both sexes. Holotype 7.0 mm long and 3.2 mm wide. Coloration nearly entirely pallid, but parts of head (especially near ocelli and Tömösváry’s organ) and antennae often slightly infuscate, very light brownish. Ocelli at least 5+1, translucid, mostly rather convex. Antennomere 6 ca 2.0–2.1 times as long as high.
Second tergite with 7–9 transverse striae (usually 8), 3 or 4 starting below, one level to, the remaining striae above schism, usually 3 or 4 (2nd to 4th or 5th from below) crossing the dorsum.
Male leg 17 (Fig. 3 A) with a rather high and irregularly shaped outer coxal lobe; telopodite 4-segmented, tarsus with two subapical spines.
Male leg 18 (Fig. 3 B) with a rather broadly arch-shaped syncoxital notch; telopodite 4-segmented.
Telopods (Fig. 3 C, D) with a rather high, apically very faintly concave, subquadrate, sparsely setose, central syncoxital lobe flanked by two setose horns with simple apices. Prefemur and, to a lesser extent, femur micropapillate laterally. Caudomedial femoral process prominent, subapically with a rounded lobe on caudal face. Caudomedial process of tibia evident, membranous; tibial tubercle on caudal face distinct, papillate. Tarsus rather strongly sigmoid, narrowly rounded apically.
Remarks: This species shows such troglomorphic traits as a nearly unpigmented body and entirely unpigmented ocelli, so it can well prove to be a troglobite. Residual coloration of the antennae and head is noteworthy.
