Qualitative and Quantitative Proteomic Analysis of Venoms from Mexican Rattlesnakes

  Qualitative and Quantitative Proteomic Analysis of Venoms from Mexican Rattlesnakes Abstract Despite the vast biodiversity of Mexican vipers, venom of endemic species has been barely studied. Here we analyzed the venom composition of three endemic species of rattlesnakes: Crotalus aquilus , C. triseriatus , and C. ravus . We used quantitative chromato-mass-spectrometry and compared venoms with C. molossus , a species commonly found in North America, in a comparative and phylogenetic framework. In total, we identified 165 proteins grouped in 19 main protein families, consistent with previous reports for viperid venoms. In C. aquilus and C. triseriatus , the most predominant protein-family type was Serine Proteases, and in C. triseriatus and C. molossus it was Snake Venom Metalloproteases. The Label-free quantification revealed a high proportion of Snake Venom Metalloproteases in C. aquilus , C. triseriatus , and C. molossus , reaching 28–47% of the total venom. In contrast, in ...

Four species of Zoica Simon, 1898 from Asia (Araneae, Lycosidae)

Abstract

Three new species of the wolf spider genus Zoica Simon, 1898 are described from eastern and southeastern parts of Asia: Zoica dulong Lu, Zhang & Wang, sp. nov. (Yunnan, ♂♀) and Z. medogensis Lu, Zhang & Wang, sp. nov. (Xizang, ♂♀) from China and Z. thailandica Lu, Zhang & Wang, sp. nov. (Ratchaburi, ♂♀) from Thailand. The male of Z. oculata Buchar, 1997 (Xizang) is described here for the first time, and the first record of the species from China is reported. Descriptions and photographs of all the species are provided.
