TL;DR: All new species described here were collected in spider webs either from the family Dipluridae (Linothele) or Lycosidae (Aglaoctenus) and therefore are assumed to be kleptoparasitic.
Abstract: The spider family Mysmenidae includes two genera in which kleptoparasitic species are known to occur, Isela and Mysmenopsis. Mysmenopsis is the most speciose with 31 species described so far. Herein, we describe twenty-one new species from Ecuador: M. alvaroi n. sp., M. amazonica n. sp., M. angamarca n. sp., M. awa n. sp., M. baerti n. sp., M. bartolozzii n. sp., M. choco n. sp., M. cube n. sp., M. corazon n. sp., M. guanza n. sp., M. guayaca n. sp., M. hunachi n. sp., M. junin n. sp., M. lasrocas n. sp., M. lloa n. sp., M. otokiki n. sp., M. pululahua n. sp., M. salazarae n. sp., M. shushufindi n. sp., M. tepuy n. sp. and M. tungurahua n. sp. We report for the first time the presence of four species of Mysmenopsis in the web of a Lycosidae, namely M. salazarae n. sp., M. shushufindi n. sp., M. bartolozzii n. sp. and M. amazonica n. sp. All new species described here were collected in spider webs either from the family Dipluridae (Linothele) or Lycosidae (Aglaoctenus) and therefore are assumed to be kleptoparasitic. New locality records are presented for M. otonga, M. fernandoi, M. atahualpa and M. penai, the female of M. penai is described for the first time. Maps of all Ecuadorian species are presented, kleptoparasitism, morphological characters and distribution of Mysmenopsis species are discussed.

TL;DR: One significant outcome of this comparative review is the entelegyne internal genitalic conformation for the family Anapidae (as opposed to haplogyne): all anapid representatives examined possess fertilization ducts.

TL;DR: The presence of Mysmenopsis in amber is further evidence of kleptoparasitic/commensal spiders in the Miocene, extending the known range from the Rupelian (Oligocene) to the Valanginian (Lower Cretaceous).
Abstract: Oonops seldeni sp. nov. and Mysmenopsis lissycoleyae sp. nov. are described from male specimens preserved in Miocene amber from the Dominican Republic and are the first fossil records of these extant genera. Gamasomorpha incerta Wunderlich, 1988 is transferred to Stenoonops. Two females previously described as Orchestina dominicana? Wunderlich, 1981 are transferred to Orchestina sp. indet., and one new specimen of a male of Orchestina dominicana Wunderlich, 1988 is identified. Oonopidae is reported for the first time from Cretaceous ambers of Burma, Lebanon and New Jersey. These are the oldest records of this family, extending the known range from the Rupelian (Oligocene) to the Valanginian (Lower Cretaceous). Recent StenoonopsMysmenopsis are unknown from Hispaniola. The presence of these genera in amber suggests that they will be found. The presence of Mysmenopsis in amber is further evidence of kleptoparasitic/commensal spiders in the Miocene.

TL;DR: Mysmenopsis furtiva, a tiny spider which lives in the funnelwebs of the Ja?
Abstract: Mysmenopsis furtiva, a tiny spider which lives in the funnelwebs of the Ja? maican diplurid spider, Ischnothele xera, behaves both as a kleptoparasite and as a com? mensal; it pilfers portions of its host's prey and also captures and consumes minute insects which are trapped in the host web and unnoticed or ignored by the host. Mysmenopsis furtiva is able to ingest hemolymph from its host's prey at a much faster rate than it can ingest material from the insects it captures. Two of its stealth strategies are to move not at all or slowly when the host is motionless and to synchronize its rapid movements with host movements. The host's anti-kleptoparasite behaviors suggest that the kleptoparasite has a significant negative impact on the host. Kleptoparasitic spiders (those which regularly steal food from other species of spiders) are known to occur in five families (Vollrath 1987; Griswold
