Molecular evolution, functional variation, and proposed nomenclature of the gene family that includes sphingomyelinase D in sicariid spider venoms.
The venom enzyme sphingomyelinase D (SMase D) in the spider family Sicariidae (brown or fiddleback spiders [Loxosceles] and six-eyed sand spiders [Sicarius]) causes dermonecrosis in mammals. SMase DExpand

Phylogenetic relationships of Loxosceles and Sicarius spiders are consistent with Western Gondwanan vicariance.
The modern geographic distribution of the spider family Sicariidae is consistent with an evolutionary origin on Western Gondwana. Both sicariid genera, Loxosceles and Sicarius are diverse in AfricaExpand

Weaponization of a Hormone: Convergent Recruitment of Hyperglycemic Hormone into the Venom of Arthropod Predators.
Arthropod venoms consist primarily of peptide toxins that are injected into their prey with devastating consequences. Venom proteins are thought to be recruited from endogenous body proteins andExpand

Diversity of Loxosceles spiders in Northwestern Africa and molecular support for cryptic species in the Loxosceles rufescens lineage.
Until recently, Loxosceles rufescens was the only species known from a geographic range including Northern Africa, Mediterranean Europe and the Middle East. Rich Loxosceles diversity in the New WorldExpand

Gene content evolution in the arthropods
Background Arthropods comprise the largest and most diverse phylum on Earth and play vital roles in nearly every ecosystem. Their diversity stems in part from variations on a conserved body plan,Expand

The phylogenetic distribution of sphingomyelinase D activity in venoms of Haplogyne spiders.
The venoms of Loxosceles spiders cause severe dermonecrotic lesions in human tissues. The venom component sphingomyelinase D (SMD) is a contributor to lesion formation and is unknown elsewhere in theExpand

Spit and venom from scytodes spiders: a diverse and distinct cocktail.
Spiders from the family Scytodidae have a unique prey capturing technique: they spit a zig-zagged silken glue to tether prey to a surface. Effectiveness of this sticky mixture is based on aExpand

Convergent setal morphology in sand-covering spiders suggests a design principle for particle capture
Sicarius and Homalonychus are unrelated, desert-dwelling spiders that independently evolved the ability to cover themselves in fine sand particles, making them cryptic against their background.Expand
