Ibotyporanga: pholcids in arid Brazilian habitats
Published in Insect Syst. Evol., 2003; http://dx.doi.org/10.1163/187631203788964926, PDF

The genus Ibotyporanga previously contained only a single species since its creation in 1944. This paper added three new species. Surprisingly, these spiders (and apparently most of their ninetine relatives) are unusual within pholcids in that they are restricted and adapted to very arid environments rather than humid forests.
