ABSTRACT
Falklandia Forster Platnick, 1985 was established for a genus of spider (Dysderoidea, Orsolobidae) in a paper published in July 1985. The homonymy with Falklandia De Broyer, 1985 (Lysianassoidea, Tryphosidae) published in October 1985 has been recognised only recently and requires a replacement name for the latter concept. An additional junior homonym, Falklandia Whatley, Chadwick, Coxhill Toy, 1987, is discussed by Brandão (in press).

Arachnida , Spiders , AnimalsABSTRACT
The family Lepechinellidae has had a complex history; described under two names, subsumed into the Dexaminidae, resurrected, and most recently treated as a subfamily within the Atylidae (Lowry Myers 2017). Lepechinellidae, based on Lepechinella Stebbing, 1908 was raised by Schellenberg (1926) to replace Dorbanellidae Schellenberg, 1925 based on Dorbanella Chevreux, 1914. The family name Lepechinellidae was used in at least ten publications until Barnard (1970) transferred the two included genera, Lepechinella and Paralepechinella Pirlot, 1933, to the Dexamininae. This arrangement was accepted tacitly or overtly by subsequent authors until Bousfield and Kendall (1994) recognized the unique nature of Lepechinella and allied genera and grouped them as Lepechinellinae within the Atylidae. Andres Brandt (2001) provided evidence to justify recognition at the family level but Lowry Myers (2017) reverted to the Bousfield Kendall (1994) position. Jim Lowry (pers. comm.) recognises that the Andres Brandt (2001) paper was not consulted by Lowry Myers (2017) and that recognition of the family Lepechinellidae is justified.

Amphipoda , AnimalsABSTRACT
The genus Paracallisoma (Crustacea: Amphipoda) is revised and the type species, Paracallisoma alberti is redescribed based on holotype material supplemented with new material from the region of the type locality. This revision results in the establishment of two new genera, Pseudocallisoma gen. nov. and Haptocallisoma gen. nov., and the description of a new species of Haptocallisoma and a new species of Paracallisoma from the North Atlantic Ocean. An account of all known species within the three genera is given and updated keys to the genera and species are provided.

Two new species of the deep-sea scavenging genus Cyclocaris (Crustacea: Amphipoda) are described from bathyal and abyssal depths in the North and tropical Atlantic Ocean, bringing the total number of species in the genus to four. An account of all four species is given and an updated key to the genus Cyclocaris is provided.
