Resumen:
Orb webs of the Chilean anapid genera Crassanapis Platnick and Forster, Sheranapis Platnickand Forster, and Elanapis Platnick and Forster are described for the first time. Crassanapisand Sheranapis species spin a typical anapid web, with one to several radii above the orbplane,going upward from the hub. Their webs are intraspecifically variable in size and architecturaldetails. Sheranapis villarrica Platnick and Forster often constructs smaller websclose to the water surface of streams. The web of Elanapis aisen Platnick and Forster is twodimensional, without orb-plane threads, like typical webs of Symphytognathidae. The webs ofMinanapis species are still unknown. Elanapis aisen has a protruding labrum, which supportsits placement in Anapidae. The spinnerets of Elanapis aisen and Crassanapis chilensis arefigured and described. The respiratory system of Elanapis aisen and Minanapis floris is described;all Chilean anapids examined so far have normal booklungs and four simple tracheaelimited to the abdomen.
