description: Lordiphosa tibetica Katoh & Gao, sp. nov.
(Pls 2A, 3I, 4I, 6A, 7I; Fig. 11)
Diagnosis. Cercus ventrally tapered, with a fringe of ca. 9 spines on apicoventral margin (Fig. 11C,F). Paramere long, distally slender and slightly sinuated, apically obliquely truncated and with minute serration, proximally Ushaped, basally broad (Fig. 11K,L).
Description (characters commonly seen in L. yangi sp. nov. not repeated) (♂, ♀). Head (Pls 2A, 3I, 4I, 6A, 7I): Frontal vitta yellowish brown. Fronto-orbital plate darker at bases of orbital setae. Ocellar triangle dark brown, marginally paler. Antennal pedicel brown; arista with 4 dorsal and 1 ventral branches. Supracervical setulae ca. 11 per side; postocular setae 17–20 per side. Cibarium with 20–22 medial and 14–16 posterior sensilla per side. Prementum with 5 (1 proximal, 1 central, 2 lateral, and 1 distal) pairs of setae.
Thorax (Pl. 2A): Postpronotal lobe yellowish brown. Scutellum brown to dark brown, laterally paler. Thoracic pleura yellowish brown.
Legs (Pl. 2A, Fig. 11A,B): Male foreleg with 4–6, 4, and 2 transverse sex-combs on 1st, 2nd, and 3rd tarsomeres, respectively; each row consisting of 2–4 teeth. Midleg 1 st tarsomere slightly longer than or as long as total length of 4 succeeding tarsomeres.
Abdomen (Pl. 2A): Tergites sometimes with dark brown, medially anteriad extended, caudal bands ca. 1/2 as wide as tergite.
Male terminalia (Fig. 11C–L): Epandrium with ca. 25 setae per side. Cercus with ca. 17 long setae. Surstylus with a row of ca. 9 prensisetae on caudodorsal margin and ca. 35 recurved setae on ventral portion of inner surface. Parameres nearly parallel with each other. Hypandrial caudolateral plates large, heavily pubescent.
Female terminalia (Fig. 11M–O): Tergite VIII caudodorsally with ca. 4 setae. Oviscapt valve apically somewhat rounded in lateral view, with ca. 16 marginal and ca. 44 minute, lateral ovisensilla. Spermathecal capsule slightly broader than long.

Holotype. ♂ (06043), Mt. Duoxiongla, Linzhi, Xizang, China, 3,500–3,800 m a.s.l., 24.ix.2010, J.J. Gao (KIZ).
Paratypes. CHINA: 4♂, 4♀ (#06024, #06026, #06028–32, #06038), same data as holotype (KIZ).
Distribution. China (Xizang).
Etymology. Pertaining to the type locality, Tibet (Xizang).
Remarks. This species resembles L. yangi sp. nov. and L. curva, but can be distinguished from L. yangi by the apically not bifurcated paramere (bifurcated into unequal branches in L. yangi) and from L. curva by the paramere sinuated distally and lacking a subapical spinule and the apically not indented spermathecal capsule (in curva: paramere distally gently curved ventrad and outward, subapically with spinule; spermathecal capsule apically indented).
