Can we resolve the taxonomic bias in spider venom research?
Toxicon: X, 2019 The rate of discovery of new spider species greatly exceeds the rate of spider venom characterisation, leading to an increasing number of species with unstudied venoms.

Venom of the Brazilian spider Sicarius ornatus (Araneae, Sicariidae) contains active sphingomyelinase D: potential for toxicity after envenomation. [PDF]
PLoS Neglected Tropical Diseases, 2013 BACKGROUND:The spider family Sicariidae includes two genera, Sicarius and Loxosceles. Bites by Sicarius are uncommon in humans and, in Brazil, a single report is known of a 17-year old man bitten by a Sicarius species that developed a necrotic lesion ...

Transcriptomic Analysis of the Spider Venom Gland Reveals Venom Diversity and Species Consanguinity
Toxins, 2019 Selenocosmia jiafu (S. jiafu) has been recently identified as a new species of spider in China. It lives in the same habitat as various other venomous spiders, including Chilobrachys jingzhao (C. jingzhao), Selenocosmia huwena (S. huwena), and Macrothele

Peptide Toxins in Solitary Wasp Venoms
Toxins, 2016 Solitary wasps paralyze insects or spiders with stinging venom and feed the paralyzed preys to their larva. Accordingly, the venoms should contain a variety of constituents acting on nervous systems.

A novel neurotoxin from venom of the spider, Brachypelma albopilosum. [PDF]
PLoS ONE, 2014 Spiders have evolved highly selective toxins for insects. There are many insecticidal neurotoxins in spider venoms. Although a large amount of work has been done to focus on neurotoxicity of spider components, little information, which is related with ...

Main Components of Spider Venoms
, 2013 Venom glands are alreadypresent in theoldes t spider group, the Mesothelae. Theglands lie in the anterior portion of the cheliceral basal segment but are very small, and it is doubtful how much the venom contributes to the predatory success.

Brown Spider (Loxosceles genus) Venom Toxins: Tools for Biological Purposes
Toxins, 2011 Venomous animals use their venoms as tools for defense or predation. These venoms are complex mixtures, mainly enriched of proteic toxins or peptides with several, and different, biological activities.
