title: Rothilena (Araneae: Agelenidae), a new genus of funnel-web spiders endemic to the Baja California Peninsula, Mexico.
abstract: Rothilena (Araneae: Agelenidae: Ageleninae), a new genus of funnel-web spiders endemic to the Baja California Peninsula in Mexico, and six new species (Rothilena griswoldi sp. nov., Rothilena cochimi sp. nov., Rothilenapilar sp. nov., Rothilena golondrina sp. nov., Rothilena sudcaliforniensis sp. nov., and Rothilena naranjensis sp. nov.) are described and illustrated. Males are diagnosed by having pedipalps with a conductor with three projections and a retrolateral tibial apophysis divided in two parts, one distal and dorsally excavated and the other retrolateral and ventrally excavated. The epigynum of females has a pair of hoods that covers part of the atrium, and the copulatory ducts resemble a "duck head".
