Among them, Pseudohampsonella bayizhena Wu & Pan, sp. nov. and Squamosa monosa Wu & Pan, sp. nov. are described as new, Pseudocaissa Solovyev & Witt and P. marvelosa (Yoshimoto) are newly recorded in China, and Miresa urga Hering and Scopelodes kwangtun- gensis Hering are reported for the first time in Xizang. The female genitalia are described for the first time in the genus Squamosa Bethune-Baker. Photographs of moths and the genitalia of new species and newly recorded species are given. A list of the Limacodidae known from Xizang, China is also included. Key words: Lepidoptera, Limacodidae, new species, Xizang, China Introduction The works of Cai (1982, 1988) reported 16 species under 15 genera of Limacodidae from Xizang, which were the results of the Comprehensive Scientific Expedition to the Qinghai-Xizang Plateau and the Mountaineering & Scientific Expedition, Chinese Academy of sciences in 1973–1976 and 1982–1984. Wu & Fang (2009a-d), Wu (2011), Wu & Solovyev (2011) and Pan, Zhu & Wu (2013) described three new species and newly recorded six more from Xizang, China based on the material collected by the Expedition Team of the Institute of Zoology, CAS in 2006. Up to date, 25 species are reported in Xizang, China. In this paper, we report another five new and little known species from Xizang, China. Among them, two species are described as new, one species is newly recorded in China, and two species are reported for the first time in Xizang. Material and methods Material examined for this study was based on the insect collections of the Institute of Zoology, Chinese Academy of Sciences (IZCAS). The photographs of moths and their genitalia are given. Methods of dissection, morphometric characters, and terminology follow Cock et al. (1987) and Holloway (1986). The type specimens of the new species are deposited in the Institute of Zoology, Chinese Academy of Sciences (IZCAS), Beijing, P. R. China.

Externally the new species is similar to P. argenta Solovyev & Saldaitis, but differs from the latter by the absence of silver scales and dark base on forewings. It is related to P. hoenei Solovyev & Saldaitis in male genitalia, but can be distinguished by the shorter length of the lobes of the uncus and the base of valva with an acute tornal corner. In the female genitalia, this new species is characterized by the longer ductus bursae and with the bisignate signum in the corpus bursae. In P. argenta Solovyev & Saldaitis and P. erlanga Solovyev & Saldaitis, the signa are composed of several small stellate sclerites. FIGURES 1–5. Adults. 1.

Pterothorax white, with scattering of brown scales. Forewing with R2 separated, R3-5 stalked. Hindwing with M1 and Rs stalked; Sc + R1 anastomosed with anterior edge of cell near base. Forewing blackish brown; antemedial fascia indistinct; postmedial fascia consisting of series of white rounded spots and a discal spot; terminal area grayish white, with proximal border running from 3/4 costa almost to the tornus, with dark brown streak on costa; fringe brown, with rare tufts of white scales. Male genitalia (Figure 6). Uncus bilobed, horn-shaped, less than valva in length, each lobe same as distal part of valva in size and slightly curved; gnathos reduced to sclerotized band connecting both lobes of the uncus; valva square-shaped proximally, with acute tornal corner and with long sickle-shaped distal part; saccus short; aedeagus almost straight, with longitudinal incision running from aedeagus apex to basal third.

WU0330 (IZCAS). Distribution. Xizang (Nyingchi). Etymology. The name is named from the locality of the type specimens. Remarks. The genus Pseudohampsonella Solovyev & Saldaitis includes three known species from China (Yunnan and Sichuan). This new species is the fourth member in the genus. Pseudocaissa Solovyev & Witt, 2009 New record for China Pseudocaissa Solovyev & Witt, 2009, Entomofauna, Supl.16: 87.Type species: Pseudocaissa apiata Solovyev & Witt, 2009. The genus is very similar to Caissa Hering externally and only the spotted white pattern is diagnostic. However, it can be easily distinguished from the latter by the reduced gnathos and a single large cornutus in the aedeagus in the male genitalia. The genus includes two species, P. marvelosa (Yoshimoto) and P. apiata Solovyev & Witt, known from Nepal and northern Vietnam. It is recorded from China for the first time. Pseudocaissa marvelosa (Yoshimoto, 1994) (Figs. 2, 8, 11) New record for China Hampsoniella [sic!] marvelosa Yoshimoto, 1994, Tinea, 14(suppl. 1): 88. Type locality: Jiri, Nepal. Pseudocaissa marvelosa (Yoshimoto): Solovyev & Witt, 2009, Entomofauna, Supl.16: 87. The species differs from P. apiata Solovyev & Witt externally by the black costal margin in the basic half of forewing and the location of the spot of the postmedial fascia near costa, which is closer to the apical spot. In male genitalia (Figure 8), the elongate valva with a large saccular process is diagnostic (Yoshimoto, 1994; Solovyev & Witt, 2009). Specimens examined.

This species is reported for the first time in China. 396 · Zootaxa 3999 (3) © 2015 Magnolia Press PAN & WU Squamosa monosa Wu & Pan, sp. nov. (Figs. 3, 9, 10, 11) Diagnosis. This new species is related to S. brevisunca Wu & Fang, but differs from the latter by the forewing with a deeper dent at R4 towards the base in the subterminal fascia and the black dot at middle of 1A being indistinct or absent. The gnathos of this new species is much shorter than that of the latter. The juxta of the new species has a single lateral process. The new species differs from S. chalcites Orhant and S. ocellata Moore by the short forks of the uncus and the shape of the juxta in the male genitalia. Forewing length 18.0–21.0mm. Body pale yellowish brown. Head yellowish brown. Antenna and labial palpus yellowish brown. Thorax and anterior 2 segments of abdomen with a longitudinal row of hair tufts. Anal hair tuft black. Forewing pale yellowish brown mixed with fine black dots, lighter towards outer margin; on outside of cell, a lustrous rounded patch bluish black inside and reddish brown outside, crossed by a light transverse line; black dot at middle of 1A indistinct or absent; subterminal fascia fine, black, bearing a deep dent at R4 towards base. Hindwing yellowish brown to dark brown. Male genitalia (Figure 9). Uncus relatively longer than S. brevisunca Wu & Fang, apically with a pair of shorter forks; gnathos thick, much shorter than uncus, apex blunt; valva relatively narrow and long, tapering to a rounded apex; juxta large, only with a single lateral process, narrow and long; aedeagus thin and straight, with a small spine at end. Female genitalia (Figure 10). Ovipositor lobes flattened, foot-shaped; anterior apophysis short, about half length of posterior apophysis; posterior apophysis long and slender; vaginal plate large, densely with minute hairs; antrum broadly funnel-shaped; ductus bursae long, slightly spiraled; corpus bursae large, rounded; signum bisignate, with minute spines.

WU0333 (IZCAS). Distribution. Xizang (Medog). Etymology. The name is derived from Greek “monos” (= single), corresponding to a single lateral process on the juxta.
