The Hon Chong‒Kâmpôt hills form a group of tiny karstic outcrops scattered in the alluvial plain across the southwestern border between Vietnam and Cambodia. This group hosts an exceptional concentration of endemic taxa that have been progressively discovered during the past two decades. Remarkable endemic genera of millipedes, mites, woodlice and...
Article
Duplex trichobothria (dx) are paired trichobothria situated near the tip of the fixed finger of the chela in pseudoscorpions of the Devonian plesion Dracochelidae and the extant superfamilies Chthonioidea and Feaelloidea. The paired condition, which is unique within Arthropoda, is here interpreted as the result of a coupling of two previously separ...

This paper summarizes the main results from taxonomic inventories drawn up as part of the ATBI of the Mercantour/Alpi Marittime parks in the French and Italian Alps. It compares the data on different groups of the invertebrate fauna published in the Zoosystema issues devoted to the ATBI with those recorded in the EDIT (European Distributed Institut...
Article
We present here the objectives, organization and preliminary results of the invertebrate inventory of the Mercantour National Park (“Terrestrial Invertebrates Module” of the ATBI Mercantour/Alpi Marittime), carried out by 68 scientists and field-collectors from 2009 to 2012. The conceptual framework of an ATBI and the interactions between inventory...

Les Arachnides du Mas de Gonon (commune de Fos-sur-Mer, Plan du Bourg, Bouches-du-Rhône) ont fait l’objet de prélèvements à l’aspirateur thermique. Parmi les 17 espèces identifiées, plusieurs sont rarement observées en France, et 5 n’ont jamais été signalées des Bouches-du-Rhône (Maso sundevalli, Agyneta mollis, Micrargus subaequalis, Trichoncus sa...
Article
The purpose of this application, under Articles 65.2.1 and 65.2.2 of the Code, is to conserve the usage of the widely used generic name Neobisium Chamberlin, 1930 and of the family-group names neobisiinae Chamberlin, 1930, neobisiidae Chamberlin, 1930 and neobisioidea Chamberlin, 1930. These names are threatened by an overlooked fixation (by monoty...

The manuscript name Chelifer longimanus Kollar, 1848, most often cited as Obisium longimanum Kollar, was first introduced in a note by Kollar (1848) that has been overlooked in the taxonomic literature on pseudoscorpions. No description or indication has been associated with this name, which is therefore a nomen nudum. It corre-sponds to the valid...
Article
Obisium Illiger, 1798 (type species Acarus cancroides Linnaeus, 1758) and Obisium Leach, 1814 (type species Chelifer trombidioides Latreille, 1804) are shown to be different nominal taxa and hence homonyms, rather than synonyms. The synonymy between Cheliferidae Westwood, 1838 (type genus Chelifer Geoffroy, 1762) and Obisiidae Sundevall, 1833 (type...

Article
: The middle Devonian (Givetian–Eifelian) pseudoscorpion Dracochela deprehendor Schawaller, Shear and Bonamo is redescribed from the type material and an additional palpal fragment. Dracochela differs from extant pseudoscorpions in having numerous spinules on the leg tarsi, the femur at least as long as the patella on the posterior legs, the stem o...

Here we study the evolution of nucleotide composition in third codon-positions of CO1 sequences of Chelicerata, using a phylogenetic framework, based on 180 taxa and three markers (CO1, 18S, and 28S rRNA; 5,218 nt). The analyses of nucleotide composition were also extended to all CO1 sequences of Chelicerata found in GenBank (1,701 taxa). The resul...
Article
Records of mites parasitizing pseudoscorpions are summarized and new host-parasite associations are reported. Trombidium brevimanum (Berlese 1910) (Trombidiidae) has been found on Neobisium bernardi bernardi Vachon 1937 in France (new country record for T. brevimanum), and T. mediterraneum on N. carcinoides (Hermann 1804) in Norway (new country rec...

Pseudoscorpions Cheliferoidea (Arachnida, Chelonethi) du Crétacé inférieur de France. Trois fossiles de pseudoscorpions sont signalés de l'ambre du Crétacé inférieur (Albien terminal) provenant d'Archingeay (Charente-Maritime, France). Ce sont les plus anciens représentants décrits de la superfamille des Cheliferoidea Risso, 1826 et les premiers ps...
Article
Chelifer eucarpus Dalman, 1826, which was previously considered a nomen dubium, is redescribed from the holotype tritonymph and transferred to the genus Withius Kew, 1911 (Withiidae). The provenance of the fossil is unknown, but it is most likely to be of East African origin (Zanzibar copal). Eucarpus Hagen, 1870 is a generic nomen nudum, based on...

Attention is drawn to the pseudoscorpion taxa published by Kyukichi Kishida (1927, 1929, 1940, 1947), which have been largely ignored in the literature outside Japan. Kishida (1929) was the first author to employ the names Chthonioidea Daday, 1888, Cheliferoidea Risso, 1826, Feaelloidea Ellingsen, 1906, Garypoidea Simon, 1879 and Olpioidea Banks, 1...
Article
Lagynochthonius fragilis n. sp. is described from a limestone cave in the Hong Chong karst of Kien Giang Province, southern Vietnam, which is currently threatened by quarrying activities. This is the first record of a troglomorphic species of Lagynochthonius Beier, 1951 from continental Asia. The presence of chemosensory setae on the dorsum of the...

Article
The holotype of Cecoditha parva Mello-Leitão 1939, from Chubut Province, Argentina, is redescribed and shown to be a typical member of the genus Austrochthonius Chamberlin 1929. The monotypic genus Cecoditha Mello-Leitão 1939 is therefore a junior subjective synonym of Austrochthonius, while the subfamily Cecodithinae Chamberlin & Chamberlin 1945 (...

Electrobisium acutum Cockerell is redescribed from a specimen cut from the block of Burmese amber containing the holotype. The presence of strong spines on the carapace and tergites indicates that E. acutum may be closely related to extant South African or Taiwanese species of the genus Clyptocheiridium Chamberlin. Electrobisium and Cryptocheiridiu...

The first known fossil of the pseudoscorpion family Sternophoridae is described from Dominican amber. The specimen, an adult female, is tentatively assigned to the extant species Idiogaryops pumilus (Hoff), known from Florida and Little Cayman Island. The incomplete state of the fossil is probably the result of scavenging while the animal was trapp...
Article
The genus Austroteneriffia Womersley is removed from synonymy with Parateneriffia Thor and redefined. Austroteneriffia hirsti Womersley, the type species, is redescribed and a second South Australian species, A. leei, sp. nov., is described. Three species are transferred to Austroteneriffia from Neoteneriffiola Hirst: A. hojoensis (Shiba & Furukawa...

Neoteneriffiola Hirst is removed from synonymy with the poorly known genus Parateneriffia Thor. A new species, Neoteneriffiola coineaui, is described from Namibia. This species can be readily distinguished from N. luxoriensis Hirst (rev. comb.), by its large size; strong, linear neotrichy of the pedal solenidia; and the relatively large dorsal plat...
Article
Ellingsenius fulleri (Hewitt and Godfrey), a bee-associated pseudoscorpion, is redescribed. New records are given for Mozambique, Oman, Iran, Cyprus and Spain. Ellingsenius somalicus Beier, from Somalia, is regarded as a junior subjective synonym. The presence of E. fulleri in Europe is probably due to human introduction. It is suggested that Hanse...
Article
The holotype male of the pseudoscorpion Pedalocreagris tethys Ćurčić, 1985 has been re-examined and found to be parasitized by an unidentified nematode. The supposed absence of the tactile seta of the telotarsus of leg IV in this species is shown to be a teratology, affecting only right leg IV of the holotype. Pedalocreagris Ćurčić, 1985 is synonym...
