Tangled in a sparse spider web: single origin of orb weavers and their spinning work unravelled by denser taxonomic sampling
In order to study the tempo and the mode of spider orb web evolution and diversification, we conducted a phylogenetic analysis using six genetic markers along with a comprehensive taxon sample. The… Expand

The male of Megacormus granosus (Gervais, 1844) with comments on its hemispermatophore (Scorpiones, Euscorpiidae)
Abstract The male of Megacormus granosus is described for the first time and the female redescribed. A homology scheme proposed recently is applied to hemispermatophore structures. The specimens were… Expand
