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.","PeriodicalId":38197,"journal":{"name":"Arachnology","volume":" 37","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135241190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
