Speciation history of the North American funnel web spiders, Agelenopsis (Araneae: Agelenidae): phylogenetic inferences at the population-species interface.
Intra- and interspecific relationships of 12 out of 13 described species as well as a potential new species in the spider genus Agelenopsis (Araneae: Agelenidae) were analyzed using sequence data from two mitochondrial genes, cytochrome oxidase I (COI) and 16S ribosomal RNA. Approximately half of the species examined formed well-supported monophyletic groups, whereas the rest of the species wer...
متن کاملPurification and characterization of two classes of neurotoxins from the funnel web spider, Agelenopsis aperta.
Two classes of paralytic toxins were isolated from the venom of Agelenopsis aperta and their chemical and larvicidal properties characterized. Five acylpolyamine toxins (alpha-agatoxins) of molecular masses 452, 488, 489, 504, and 505 Da produce immediate but reversible paralysis in Manduca sexta following injection. Six insecticidal peptides (mu-agatoxins) produce a gradual but irreversible pa...

Rothilena (Araneae: Agelenidae: Ageleninae), a new genus of funnel-web spiders endemic to the Baja California Peninsula in Mexico, and six new species (Rothilena griswoldi sp. nov., Rothilena cochimi sp. nov., Rothilenapilar sp. nov., Rothilena golondrina sp. nov., Rothilena sudcaliforniensis sp. nov., and Rothilena naranjensis sp. nov.) are described and illustrated. Males are diagnosed by hav...
متن کاملComparative analysis of tissue-specific transcriptomes in the funnel-web spider Macrothele calpeiana (Araneae, Hexathelidae)
The funnel-web spider Macrothele calpeiana is a charismatic Mygalomorph with a great interest in basic, applied and translational research. Nevertheless, current scarcity of genomic and transcriptomic data of this species clearly limits the research in this non-model organism. To overcome this limitation, we launched the first tissue-specific enriched RNA-seq analysis in this species using a su...
متن کاملo-Agatoxins: Novel Calcium Channel Antagonists of Two Subtypes from Funnel Web Spider (Agelenopsis uperta) Venom*
A new series of polypeptide presynaptic antagonists (((w-agatoxins”) was purified from venom of the funnel web spider Agelenopsis aperta. Physiological data indicate that all of these peptides are antagonists of voltage-sensitive calcium channels. Although all three w-agatoxins (Aga) described here (w-Aga-IA, w-AgaIB, and w-Aga-IIA) block insect neuromuscular transmission presynaptically, bioch...
