Lordiphosa spatulata Katoh & Gao, sp. nov.

(Pls 2E, 3M, 4M, 6E, 7M; Fig. 15)

Diagnosis. Cercus ventrally elongated, with a tuft of 6–7 spines around ventral apex (Fig. 15C,D,F). Hypandrial caudolateral lobes unpubescent (Fig. 15I –K). Paramere nearly straight but slightly sinuate subapically, apically pointed (Fig. 15I –L). Gonopods dorsomedially roundly concaved in lateral view, sharply angled at caudoventral corners (Fig. 15K,L). Aedeagus apically somewhat dilated in ventral view (Fig. 15I); apodeme directed at acute angle to aedeagus (Fig. 15K).

Description (characters commonly seen in L. yangi sp. nov. not repeated) (♂). Head (Pls 2E, 3M, 4M, 6E, 7M): Frontal vitta, fronto-orbital plate, and ocellar triangle yellowish brown. Occiput medially paler. Postgena dark brown, laterally somewhat paler. Antennal 1 st flagellomere pale yellow; arista with 4 dorsal and 2 ventral branches. Supracervical setulae 13¯15 per side; postocular setae 16–19 per side. Clypeus brown, dorsally darker. Cibarium with ca. 24 medial and ca. 17 posterior sensilla per side. Prementum with 5 (1 proximal, 2 lateral, and 2 distal) pairs of setae.

Thorax (Pl. 2E) yellowish brown. Mesonotum caudomedially darker, without stripe. Acrostichal setulae in ca. 6 irregular rows. Mid katepisternal seta distinctly longer than those below it.

Legs (Pl. 2E, Fig. 15A,B): Male foreleg with 2, 2, and 1 transverse sex-combs on 1st, 2nd, and 3rd tarsomeres, respectively; each row consisting of 2–4 teeth. Fore- and midleg 1 st tarsomeres nearly as long as total length of 4 succeeding tarsomeres.

Abdomen (Pl. 2E): Tergites grayish brown, caudally with dark grayish brown, narrow, marginal bands.

Male terminalia (Fig. 15C–L): Epandrium dorsomedially pale yellowish brown, with ca. 16 long setae per side; ventral lobe apically narrowly extended. Cercus pubescent except for lateral margin, with ca. 21 long setae; lateral margin sclerotized. Surstylus with a row of 1 3–15 prensisetae on caudodorsal margin and ca. 22 recurved setae on ventral portion of inner surface. Aedeagus membranous except for apical portion, subapically to medially sheathed with gonopods; apodeme rod-shaped, not dilated apically, much shorter than aedeagus.

Holotype. ♂ (#06034), Mt. Duoxiongla, Linzhi, Xizang, China, 3,500–3,800 m a.s.l., 24.ix.2010, J.J. Gao (KIZ).

Distribution. China (Xizang).

Etymology. From Latin word “ spatulata ” (meaning “like spatula”), referring to the apical shape of paramere somewhat likes painting-knife.

Remarks. This species resembles L. tripartita, L. paradenticeps, L. vittata, L. gruicollara, and L. eminens in sharing the following characters: cercus ventrally elongated (except for L. paradenticeps), with a tuft of spines around ventral apex; paramere basally not so strongly curved; aedeagal apodeme rod-shaped, apically not dilated, much shorter than aedeagus; hypandrial caudolateral lobes unpubescent. However, this species can easily be distinguished from them by the paramere nearly straight but slightly sinuate subapically and the gonopods sharply angled at caudoventral corners.
