The tengellid spiders (family Tengellidae) include only eight genera and a little over 30 species worldwide. The family is confined to the New World and Madagascar (one species and genus). The characters defining the family are technical and there are still some disagreements as to its size and placement within spider classification.
Some of these strange spiders look like a cross between a crab spider and a sac spider, as in the American genus Lauricius. This is another of the families carved of the catchall family Clubionidae over the last 20 or so years.
