''Mysmenopsis'' is a
kleptoparasitic genus of tiny tropical and subtropical American spiders in the family
Mysmenidae. Most live in the funnelwebs of spiders in the family
Dipluridae
The family Dipluridae, known as curtain-web spiders (or confusingly with other distantly related ones as funnel-web tarantulas) are a group of spiders in the infraorder Mygalomorphae, that have two pairs of booklungs, and chelicerae (fangs) that ...
. ''M. archeri'' lives on webs of a species in the family
Pholcidae, ''M. capac'' and ''M. cienaga'' have been observed living in ''
Cyrtophora'' (

Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name ...
) webs. One reason why diplurid webs are preferred seems to be that they are persistent in time and space, sometimes spanning several years.
The monotypic genus ''
Isela'' is closely related.
''Mysmenopsis furtiva'' from
Jamaica lives as a kleptoparasite and
commensal in webs of ''
Ischnothele xera''. It steals portions of its host's prey, but also consumes minute trapped insects that are not sought after by the host. In order not to be recognized, it moves only slowly when the host does not move; else it synchronizes its rapid movements with the movements of the host. ''M. furtiva'' has been observed to feed on one end of a prey animal, while the host feeds on the other. When feeding, its legs and pedipalps remain motionless, but its abdomen sways slowly and slightly. One feeding bout can double its abdominal volume. The host shows anti-kleptoparasite behavior, amongst others by adding silk between the kleptoparasite and the feeding site.
The closely related ''M. furtiva'' and ''M. monticola'' parasitize two spider species that are also closely related, and it is believed that the two groups
coevolved.
