In a review from 2005 on ballooning in spiders and other animals, Pholcidae are marked as a “family in which ballooning has been observed”. Here I review the evidence for this, and conclude that there is no reliable data showing that Pholcidae have a behaviour that evolved to function specifically for getting airborne. Ballooning may in fact be absent in a large clade of spiders including Pholcidae (i.e. Haplogynae, or Synspermiata). Other behaviours that share certain characteristics with ballooning and that may accidentally result in airborne specimens occur in Pholcidae: bridging and dropping on a line.

Two new genera, Bermejoa gen. nov. and Isiboroa gen. nov. are described to house the species Bermejoa zoeae sp. nov. and Isiboroa hamelae sp. nov., respectively. Two new species of existing genera are also described: Plesiopelma manni sp. nov. and Reversopelma herzogi sp. nov. Homoeomma peruvianum (Chamberlin, 1916) and Acanthoscurria sacsayhuaman Ferretti, Ochoa & Chaparro, 2016 from Peru are transferred to Isiboroa gen. nov., based on palpal bulb morphology and the absence of a stridulation organ. Consequently, the new combinations Isiboroa peruviana comb. nov. and Isiboroa sacsayhuaman comb. nov. are proposed.

We present a taxonomic study with the description of three new species of Chira Peckham & Peckham, 1896: C. stolari sp. nov. (♂♀) from Pernambuco, Brazil; C. ivyatenea sp. nov. (♂♀) from Misiones, Argentina and Santa Catarina, Brazil; and C. hanagarthi sp. nov. (♀) from La Paz, Bolivia; and a tentative identification key for 12 (of 14 known) species of this Central and South American genus. Some misidentifications of C. lanei Soares & Camargo, 1948 and C. lucina Simon, 1902 are resolved.

Castianeira monai sp. nov. is described based on specimens from south- western Paraguay and southern Bolivia, the new species has a distribution in Humid Chaco and the Beni Savanna ecoregion. The new species is distinct in embolic morphology with two thicker basal coils and four thinner tapering coils to apex, also the proportions of anterior eyes, the presence of distinct anterior abdominal spines, tibia I ventral spination 3-2 and a bright red abdomen and orange carapace separate this species from Neotropical congeners.

Palaeophonus arctus Matthew, 1895, from the late Carboniferous Fern Ledges of Nova Scotia, Canada, and Palaeophonus lightbodyi Kjellesvig-Waering, 1954, from the Silurian of Ludford Lane in England, are problematic names proposed for fossil scorpions (Arachnida: Scorpiones). Matthew's name has been widely overlooked in the literature, but features in online resources such as the Paleobiology Database, where it currently extends the stratigraphic range of the genus Palaeophonus Thorell & Lindström, 1884 from the Silurian into the Carboniferous. The fossil on which it is based cannot be interpreted with confidence as a scorpion. Kjellesvig-Waering's name is based on an isolated pedipalp chela, which lacks characters justifying its placement in Palaeophonus or any other Palaeozoic scorpion genus. Both names are treated here as nomina dubia. We also take the opportunity to synonymize Allopalaeophonus Kjellesvig-Waering, 1986 with Palaeophonus. These two mid-Silurian genera are currently placed in separate infraorders, but the holotype of Allopalaeophonus caledonicus (Hunter, 1886) is very similar in habitus to the type species of Palaeophonus: Palaeophonus nuncius Thorell & Lindström, 1884. The single character currently separating the genera, mesosomal sternite shape, is unconvincing.

Abstract The type material of three species of the endemic genus Tecution Benoit, 1977 on Saint Helena are re-examined. Tecution helenicola Benoit, 1977 syn. nov. and Tecution mellissi (O. Pickard-Cambridge, 1873) syn. nov. are synonymized with Tecution planum (O. Pickard-Cambridge, 1873), based on identical palpal morphology and the discovery of a gradient of cheliceral size variation in a large amount of non-type material from Saint Helena Island. A brief discussion on the habitat and ecology of T. planum is provided.

Abstract The Serra de Piquiatuba is situated in the area of the 8th Battalion of Engineering and Construction—8° BEC, located at km 8 of the Santarém–Cuiabá highway, in the municipality of Santarém, Pará, Brazil. This region is characterized by a hot and humid climate with rainfall exceeding 1900 mm p.a. In this study, we present a species list of scorpions from the Serra de Piquiatuba, based on data collected from September to November 2010. Five species were recorded, all common in the Amazon, belonging to the families Buthidae and Chactidae. The observed diversity patterns are discussed considering other scorpion inventories carried out in Brazil and possible sampling biases. The present study raises methodological questions to be further addressed in scorpion community ecology studies.
