none - not entered - only general mention of Braconidae without stating species. The relationships of the about 17 families of the spider superfamily Dysderoidea (Araneae) are discussed, a key, revised diagnoses and cladograms are given. Members of at least ten families are known in Baltic and/or Dominican amber: the first fossil species of the families Plectreuridae and Telemidae are described. Questionable juvenile members of the Scytodidae - or Drymusidae? - are described which possess a low prosoma in contrast to extant Scytodidae. Diguetidae GERTSCH 1949 is downgraded to a subfamily of the Plectreuridae BANKS 1898 (n. stat.), Loxoscelidae is regarded as a family of its own and Rhodinae (Dysderidae) is regarded in a strict sense. Psilodercinae DEELEMAN-REINHOLD 1995 (Ochyroceratidae) may be a family of its own, Theotiminae DEELEMAN-REINHOLD 1995 may be regarded as a tribus of the Ochyroceratinae. Onchyroceratidae is regarded as the sister group to the Pholcidae, Periegopidae as the sister group of the Plectreuridae and Segestriidae as the sister group of Periegopidae + Plectreuridae. - Fossil taxa of 11 or 12 spider families of the superfamily Dysderoidea are dealt with, 9 or 10 families in Baltic amber: Dysderidae, Leptonetidae, Oonopidae, Pholcidae, Plectreuridae, Scytodidae, Segestriidae, Telemidae, Tetrablemmidae, and questionable Drymusidae, and 8 families in Dominican amber: Caponiidae, Ochyroceratidae, Oonopidae, Pholcidae, Scytodidae, Segestriidae, Loxoscelidae and Tetrablemmidae. - The following taxa are described from in Baltic amber: Questionable Drymusidae (within the Scytodidae): Gen. et sp. indet.; Dysderidae: Dasumiana n. gen., D. emicans n. sp., D. valga n. sp., Harpactea communis n. sp.; Eoleptoneta curvata n. sp., E. duocalcar n. sp., E. similis n. sp., Oligoleptoneta n. gen., O. altoculus n. sp.; Oonopidae: Orchestina gracilitibialis n. sp., ?Stenoonops rugosus n. sp.; Pholcidae: Paraspermophora n. gen., P. bitterfeldensis n. sp., P. perplexa n. sp., P. sp. indet., Pholcidae gen. et sp. indet.; Palaeoplectreurys n. gen. P. baltica n. sp.; Scytodidae: Gen. et sp. indet.; Segestriidae: Ariadninae n. subfam., Ariadna defuncta n. sp., Segestria flexio n. sp., S. mortalis n. sp., Vetsegestria n. gen., V. quinquespinosa n. sp.; Telemidae: ?Telema moritzi n. sp., ?T. sp. indet.; Tetrablemmidae: Balticoblemma n. gen., B. unicorniculum n. sp. Numerous taxa are revised. - A parasitic fossil mite (Acari: Microtrombidiidae or Trombidiidae) is described which is sucking at the prosoma of a female of the genus Orchestina SIMON (Oonopidae); a fossil male of Segestria sp. indet. (Segestriidae) is reported close to a parasitoitic wasp (Braconidae); a fossil ant and a Diptera are reported as prey of Dysderoidea, remains of spermatozoa and droplets of a capture web are reported from members of the family Tetrablemmidae. - Palaeoplectreurys baltica (Plectreuridae) is the first Palearctic member of this New World's family. Some special spider taxa are reported from the Bitterfeld deposit. - Some fossil members of the families Dysderidae and Segestriidae may have been aggressive ant mimics. -The following taxa are described from Dominican amber: Arachnolithulus longipes n. sp. (Ochyroceratidae), ?Coryssocnemis velteni n. sp. and Loxosceles aculicaput n. sp. (Loxoscelidae).
