52, see text Mysmenopsis is a kleptoparasitic genus of tiny tropical and subtropical American spiders in the family Mysmenidae.
One reason why diplurid webs are preferred seems to be that they are persistent in time and space, sometimes spanning several years.
Mysmenopsis furtiva from Jamaica lives as a kleptoparasite and commensal in webs of Ischnothele xera.
When feeding, its legs and pedipalps remain motionless, but its abdomen sways slowly and slightly.
The host shows anti-kleptoparasite behavior, amongst others by adding silk between the kleptoparasite and the feeding site.
