TL;DR: A new pseudoscorpion classification is proposed with two new suborders, Epiocheirata and IocheIRata, based upon a cladistic analysis of relationships within the order, and the systematic position of the Devonian family Dracochelidae is discussed.
Abstract: A new pseudoscorpion classification is proposed with two new suborders, Epiocheirata and Iocheirata, based upon a cladistic analysis of relationships within the order. The Epiocheirata contains two super- families: Chthonioidea for Chthoniidae, Tridenchthoniidae and Lechytiidae, stat. nov. (for Lechytia), and Feaelloidea for Feaellidae and Pseudogarypidae. The Iocheirata is divided into two infraorders: Hemictenata Balzan and Panctenata Balzan. The Hemictenata contains a single superfamily, Neobisioidea for Bochicidae, Gymnobisiidae, Hyidae, Ideoroncidae, Neobisiidae, Parahyidae, fam. nov. (for Parahya) and Syarinidae. The Panctenata contains two microorders: Mestommatina, nov, with Garypoidea for Cheiridiidae, Garypidae, Geogarypidae, Larcidae, fam. nov. (for Archeolarca and Larca) and Pseudochiridiidae, and Olpioidea for Menthidae and Olpiidae; and Elassommatina, nov. with Sternophoroidea, stat. nov, for Sternophoridae, and Cheliferoidea for Atemnidae, Cheliferidae, Chernetidae and Withiidae. The Vachoniidae is synonymised with the Bochicidae, and the Cheiridioidea is treated as a synonym of Garypoidea. Philomaoria Chamberlin and Philomaoriini are transferred from the Withiidae to the Cheliferidae. The chthoniid tribe Pseudotyrannochthoniini is elevated to subfamily rank, and the systematic position of the Devonian family Dracochelidae is discussed.
TL;DR: A new pseudoscorpion, Lagynochthonius bailongtanensis sp.
Abstract: A new pseudoscorpion, Lagynochthonius bailongtanensis sp. nov., is described and illustrated from specimens collected in a cave in Luoping County, Yunnan Province, China. This species is notable in being strongly troglomorphic. A new identification key is provided to all known Chinese representatives of the genus Lagynochthonius.
TL;DR: The Australian pseudoscorpionid fauna, as now known, includes representatives of 7 families and 24 genera, of which Austrohorus (Olpiidae, type species exsul mihi, Western Australia) and Paraustrochernes (Chernetidae) are described as new.
Abstract: The Australian pseudoscorpionid fauna, as now known, includes representatives of 7 families and 24 genera, of which Austrohorus (Olpiidae, type species exsul mihi, Western Australia) and Paraustrochernes (Chernetidae, type species victorianus mihi, Victoria) are described as new. Tubbichthonius Hoff (Chthoniidae) is considered to be a synonym of Pseudotyrannochthonius Beier. Of the 53 Australian species, to which a key is given, 12 are described as new, namely-Chthoniidae : Sathrochthonius crassidens, Tyrannochthonius (Tyrannochthonius) laevis, T. (Lagynochthonius) australicus, Pseudotyrannochthonius bornemisszai, P. australiensis; Olpiidae: Austrohorus exsul, Xenolpium squalidum, X. bornemisszai; Garypidae: Synsphyronus (Maorigarypus) fallaciosus; Chernetidae: Nesidiochernes australicus, Paraustrochernes victorianus; Cheliferidae: Protochelifer victorianus. No new specific synonymy is recorded.
TL;DR: Two new troglomorphic pseudoscorpion species are described from the dark zone of caves in the tower karst of the Guizhou Province in China, likely to have very restricted distribution ranges.
Abstract: Two new troglomorphic pseudoscorpion species, Tyrannochthonius harveyi, sp. nov. and Tyrannochthonius zhai, sp. nov., are described from the dark zone of caves in the tower karst of the Guizhou Province in China. Both species are presently known only from single caves and are likely to have very restricted distribution ranges.
