  A Paradigm Shift in Snakebite Envenoming Therapy: From Conventional Antivenoms to Rationally Designed, Broadly Neutralizing Combination Therapies Abstract For over a century, polyclonal antivenom has been the cornerstone of snakebite therapy, saving countless lives. However, the current production method, based on immunizing large animals, has inherent limitations in terms of safety, stability, and supply reliability, thereby creating a pressing need for alternative technologies. This review charts the rise of next-generation antivenoms built on recombinant antibody engineering. We systematically survey the strategies for discovering and developing these molecules, from humanized monoclonal antibodies and VHHs to computationally designed proteins. Our central thesis is that achieving broad-spectrum neutralization against complex venoms requires a shift from single-agent approaches to rationally designed, oligoclonal “cocktail” therapies (defined mixtures of a few select therapeut...

Abstract
Four new genera in three spider families are reported, namely Langlibaitiao Lin & Li, gen. nov., of Dictynidae O. Pickard-Cambridge, 1871, with Lathys inaffecta Li, 2017 (♂♀, China: Guangxi) as the type species; Huoyanluo Lin & Li, gen. nov., of Macrobunidae Petrunkevitch, 1928, with Huoyanluo ruanxiaoqi Lin & Li, sp. nov. (♂, China: Yunnan) as the type species and Gushangzao Lin & Li, gen. nov. and Gyro Lin & Li, gen. nov., of Theridiidae Sundevall, 1833, with Gushangzao shiqian Lin & Li, sp. nov. (♂♀, China: Xizang) and Gyro zeppeli Lin & Li, sp. nov. (♀, China: Yunnan) as the type species, respectively. Further 31 new species in 19 spider families are reported, including Agelenidae C.L. Koch, 1837: Troglocoelotes doul Lin & Li, sp. nov. (♀, China: Guangxi) and T. ruanxiaowu Lin & Li, sp. nov. (♀, China: Guangxi); Dictynidae: Langlibaitiao zhangshun Lin & Li, sp. nov. (♂, China: Hainan); Hahniidae Bertkau, 1878: Hahnia zhuyifani Lin & Li, sp. nov. (♀, China: Yunnan); Liocranidae Simon, 1897: Platnick xintongi Lin & Li, sp. nov. (♂♀, China: Xizang); Macrobunidae: Funny yanqing Lin & Li, sp. nov. (♂♀, China: Xizang) and Huoyanluo zhangzezhongi Lin & Li, sp. nov. (♂♀, China: Yunnan); Mysmenidae Petrunkevitch, 1928: Phricotelus yangxiong Lin & Li, sp. nov. (♂♀, China: Chongqing); Nemesiidae Simon, 1889: Raveniola shixiu Lin, Wang & Li, sp. nov. (♀, China: Guangxi) and R. xiezhen Lin, Wang & Li, sp. nov. (♂♀, China: Yunnan); Nesticidae Simon,1894: Speleoticus sicet Lin & Li, sp. nov. (♂♀, China: Sichuan); Ochyroceratidae Fage, 1912: Speocera yiduoi Lin & Li, sp. nov. (♂♀, China: Guangdong); Oecobiidae Blackwall, 1862: Uroctea chenyui Lin & Li, sp. nov. (♂♀, China: Guangxi); Oonopidae Simon, 1890: Orchestina xiebao Lin & Li, sp. nov. (♀, China: Chongqing); Philodromidae Thorell, 1869: Apollophanes lujiani Lin & Li, sp. nov. (♂♀, China: Guangxi) and Psellonus dawanqu Lin & Li, sp. nov. (♂♀, China: Guangdong); Salticidae Blackwall, 1841: Coccorchestes spark Lin & Li, sp. nov. (♂♀, Indonesia, West Papua), Onomastus zhuwu Lin & Li, sp. nov. (♂♀, China: Chongqing) and Synagelides huangxin Lin & Li, sp. nov. (♂♀, China: Chongqing); Sparassidae Bertkau,1872: Thelcticopis chongzu Lin & Li, sp. nov. (♂♀, China: Yunnan); Symphytognathidae Hickman,1931: Kirinua zhengqizhangi Lin & Li, sp. nov. (♀, China: Guangxi); Synotaxidae Simon,1895: Tekellina haosiwen Lin & Li, sp. nov. (♂♀, China: Chongqing) and T. huihangi Lin & Li, sp. nov. (♂♀, China: Zhejiang); Theridiidae: Chrosiothes pengqi Lin & Li, sp. nov. (♀, China: Chongqing), Coscinida hantao Lin & Li, sp. nov. (♂♀, China: Chongqing), Gushangzao goemon Lin & Li, sp. nov. (♂♀, Japan, Iriomotejima Island), Theridion chenzhangfui Lin & Li, sp. nov. (♂♀, China: Zhenjiang) and Yaginumena xuanzan Lin & Li, sp. nov. (♂♀, China: Chongqing); 2 Lin et al. Theridiosomatidae Simon, 1881: Coddingtonia chenyufengi Lin & Li, sp. nov. (♀, Vietnam: Hai Phong) and Sennin zhangxinae Lin & Li, sp. nov. (♂♀, Vietnam: Hai Phong); Zodariidae Thorell, 1881: Mallinella zhoushengboi Lin & Li, sp. nov. (♂♀, China: Chongqing). Four new combinations in three spider families are proposed: Philodromidae: Psellonus kianganensis (Barrion & Litsinger, 1995) comb. nov.; Theridiidae: Gushangzao pelorosus (Zhu, 1998) comb. nov. and Dictynidae: Langlibaitiao chishuiensis (Zhang, Yang & Zhang, 2009) comb. nov. and Lan. inaffectus (Li, 2017) comb. nov.
