RESUMO
Background: Lysiteles Simon, 1895 contains 64 nominal species distributed in East, South and South Asia. It possesses very high species diversity in China (with 46 and 32 endemics), Bhutan (with 9 and 1 endemic) and Nepal (with 8 and 4 endemics).In June 2023, a spider survey of Cibagou National Nature Reserve, Xizang, China was carried out. After examination and morphological comparison, two Lysiteles species were recognised as new to science. New information: Two new species of Lysiteles Simon, 1895 collected from Cibagou National Nature Reserve, Xizang, China are described: L.cibagou sp. nov. (ââ) and L.tangi sp. nov. (ââ). Diagnostic photos of habitus and copulatory organs and a distributional map are provided.

RESUMO
The orb-weaver spider genus Gea C.L. Koch, 1843 from China is revised, and three species including one new species, are recognized: Geajingdong Mi, Wang & Gan, sp. nov. (ââ) from Yunnan; Geaspinipes C.L. Koch, 1843 (ââ) from Guangdong, Guangxi, Guizhou, Hainan, Taiwan, and Yunnan; and Geasubarmata Thorell, 1890 (ââ) from Guangxi and Hainan. Geasubarmata is newly recorded in China.
RESUMO
Lycodongammiei (Blanford, 1878), a rarely encountered species of Asian snake, is characterized by ambiguous systematics and biology. Based on a sole specimen of L.gammiei rediscovered in southeastern Xizang, China, we conduct a detailed morphological examination and description, and investigate the systematic position of this species. Morphologically, the newly collected specimen is closely aligned with specimens previously described. Mitochondrial DNA-based phylogenetic analyses reveal that L.gammiei constitutes an independent evolutionary lineage, forming a clade with L.fasciatus (Anderson, 1879), L.gongshan Vogel & Luo, 2011, L.butleri Boulenger, 1900, and L.cavernicolus Grismer, Quah, Anuar, Muin, Wood & Nor, 2014. The closest genetic distance between L.gammiei and its congeners was 10.2%. The discovery of L.gammiei in Medog County, China, signifies an eastward expansion of its known geographical distribution.

RESUMO
Based on morphological and molecular evidence, Argiope macrochoera Thorell, 1891 from China is found to be the unknown female of A. cameloides Zhu & Song, 1994, the known male of A. perforata Schenkel, 1963 is mismatched and provisionally suggested to be the male of A. boesenbergi Levi, 1983, and the true male of A. perforata Schenkel, 1963 is described for the first time.

Two new species of the orb-weaver genus Chorizopes from Yunnan Province, China are described: Chorizopes albussp. n. (male and female) from the Gaoligong Mountains and Ailao Mountains, and Chorizopes longussp. n. (male and female) from the Gaoligong Mountains. Chorizopes albussp. n. can be distinguished from the related species Chorizopes shimenensis by: 1) median apophysis widest at the middle part versus widest at the base in the latter; 2) median apophysis without the dorsal spur found in that of the latter; 3) spermathecae spherical versus ovoid in the latter; 4) having one pair of large white spots on posterior lateral area of abdomen versus having two pairs of crescent white patches with dark edges on dorsal abdomen in the latter. Chorizopes longussp. n. can be separated from the similar species Chorizopes tumens by: 1) the median apophysis having a knob on the distal half versus having a knob on the basic half in the latter; 2) male palp having a spur versus absent in the latter; 3) the width of the groove between the paracymbium and cymbium as thick as the paracymbium versus two times as thick as the paracymbium in the latter; 4) copulatory duct attached on anterior ventral of the spermatheca versus on anterior dorsal in the latter. Photos of body and copulatory organs, line drawings of copulatory organs, as well as the distribution data are provided. The type specimens are deposited in the College of Life Sciences, at the Hunan Normal University (HNU) and the Museum of Tongren University (MTU).
