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 ...

Taxonomic revision of the genus Ceropales Latreille, (Hymenoptera: Pompilidae, Ceropalinae) from Saudi Arabia, with the description of two new species

ABSTRACT

The genus Ceropales Latreille, (Hymenoptera: Pompilidae, Ceropalinae) from Saudi Arabia is reviewed. Specimens were primarily collected from the south-western region of the country (Jazan Province). Five species are recognised, of them C. (Ceropales) pseudoaustralensis Gadallah & Malash, sp. n. and C. (Hemiceropales) subcribrata Malash & Gadallah, sp. n. are described and illustrated. An illustrated key and a list of all Ceropales species recorded in Saudi Arabia are also provided.
