The type material of Pamphobeteus ultramarinus Schmidt, 1995 and P. vespertinus (Simon, 1889) are redescribed. The male of P. lapola Sherwood, Gabriel, Brescovit & Lucas, 2022 is described for the first time. Six new species are described: P. amazonas Sherwood, Gabriel, Peñaherrera-R., Cisneros-Heredia., León-E., Brescovit & Lucas sp. nov. from Brazil, and P. gangotenai Cisneros-Heredia, Peñaherrera-R., León-E., Sherwood, Gabriel, Brescovit & Lucas, sp. nov., P. jamacoaque Peñaherrera-R., Cisneros-Heredia., León-E., Sherwood, Gabriel, Brescovit & Lucas sp. nov., P. lasjuntas Peñaherrera-R., Cisneros-Heredia., León-E., Sherwood, Gabriel, Brescovit & Lucas sp. nov., P. matildeae Sherwood, Gabriel, Peñaherrera-R., Cisneros-Heredia., León-E., Brescovit & Lucas sp. nov., and P. skis León-E., Peñaherrera-R., Cisneros-Heredia, Sherwood, Gabriel, Brescovit & Lucas sp. nov. from Ecuador. We report, for the first time, the presence of Type III urticating setae in Pamphobeteus Pocock, 1901. New interpretations of tibial apophysis morphology are presented, alongside a comparison of the palpal bulb morphology of all known male congeners. New distribution and/or museum records are made for P. antinous Pocock, 1903, P. crassifemur Bertani, Fukushima & Silva, 2008, P. lapola, and P. urvinae Sherwood, Gabriel, Brescovit & Lucas, 2022. Pamphobeteus petersi Schmidt, 2002 is illustrated and transferred to the genus Megaphobema Ausserer, 1875, based on palpal bulb morphology, and proposed as a junior synonym of Megaphobema velvetosoma Schmidt, 1995 syn. nov. Two Costa Rican species currently housed in Megaphobema are found to be misplaced, based on genital, femoral, and stridulation organ morphology, and are transferred to Abdomegaphobema gen. nov., Thus creating the new combinations Abdomegaphobema mesomelas (O. Pickard-Cambridge, 1892) comb. nov. and Abdomegaphobema peterklaasi (Schmidt, 1994) comb. nov.

A new species of the poorly known mygalomorph genus Strophaeus Ausserer, 1875 is described. The new species, Strophaeus quillacinga sp. nov., is described from Nariño, Colombia. It represents the first record of Strophaeus from Colombia, with the genus previously only known from Peru, Brazil, and Panama. This species can be distinguished from other known female congeners by the presence of a higher number of spines on the rastellum and the abdomen dorsally mottled.

Abstract A newly discovered species of Masteria L. Koch, 1873 collected at two Danish tropical hothouses, Masteria boggildi sp. n., is described. It is the first member of Dipluridae (curtain-web spiders) known to have established breeding populations in Europe. The new species belong to a subgroup of Masteria species characterized by six eyes, piriform bulb, and short, unevenly sized inner and outer spermathecal lobes. Masteria boggildi sp. n. appears most closely related to Neotropical species, particularly to species found in Ecuador. Possible paths to its introduction are suggested.
