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 ...

A new species of Neoantistea Gertsch, 1934 from Yintiaoling National Nature Reserve, Chongqing, China (Araneae, Hahniidae

Background

Hahniidae is a family of spiders with 239 species belonging to 29 genera, of which 45 species belong to 9 genera was recorded in China.

New information

A new species of the genus Neoantistea Gertsch, 1934 is described from Yintiaoling Nature Reserve: N. yintiaoling sp. nov. (♂). Morphological descriptions, photos and illustrations of copulatory organs are provided. Photos of N. quelpartensis Paik, 1958 are also presented in order to compare it with new species.
