Cryptothele species have a particular conformation of the spinning field of the anterior lateral spigots that is typical of zodariids and close relatives: the field of major ampullate gland spigots, together with their strain sensilla, are invaginated within the field of piriform gland spigots. The implantation of the teeth on the inner side of the leg tarsal claws is also consistent with its placement among zodariids. We added Cryptothele to a morphological dataset of zodariid genera, together with the outgroups Homalonychus (Homalonychidae) and Penestomus (Penestomidae). The phylogenetic analysis concludes that the genus Cryptothele is a member of the subfamily Cydrelinae, which by priority is here considered a junior synonym of Cryptothelinae. Cryptothele specimens cover most of their body with soil particles which become consolidated as mud, and the debris is probably held in place by curved setae covered by long barbs. The spinnerets, which can be retracted and hidden, as well as the booklungs, are surrounded by a crown of thick setae that are densely covered by short barbs, protecting those areas against soil particles. Cryptothele are probably specialized to prey on termites, and their phylogenetic placement indicates that this diet specificity evolved two times independently in zodariids.} }
