  • The Short-Range Endemic Invertebrate Fauna of the Ravensthorpe Range
    THE SHORT-RANGE ENDEMIC INVERTEBRATE FAUNA OF THE RAVENSTHORPE RANGE MARK S. HARVEY MEI CHEN LENG Department of Terrestrial Zoology Western Australian Museum June 2008 2 Executive Summary An intensive survey of short-range endemic invertebrates in the Ravensthorpe Range at 79 sites revealed a small but significant fauna of myriapods and arachnids. Four species of short-range endemic invertebrates were found: • The millipede Antichiropus sp. R • The millipede Atelomastix sp. C • The millipede Atelomastix sp. P • The pseudoscorpion Amblyolpium sp. “WA1” Atelomastix sp. C is the only species found to be endemic to the Ravensthorpe Range and was found at 14 sites. Antichiropus sp. R, Atelomastix sp. P and Amblyolpium sp. “WA1” are also found at nearby locations. Sites of high importance include: site 40 with 7 species; sites 7 and 48 each with 5 species; and sites 18 and 44 each with 4 species. WA Museum - Ravensthorpe Range Survey 3 Introduction Australia contains a multitude of terrestrial invertebrate fauna species, with many yet to be discovered and described. Arthropods alone were recently estimated to consist of approximately more than 250,000 species (Yeates et al. 2004). The majority of these belong to the arthropod classes Insecta and Arachnida, and although many have relatively wide distributions across the landscape, some are highly restricted in range with special ecological requirements. These taxa, termed short-range endemics (Harvey 2002b), are taxa categorised as having poor dispersal abilities and/or requiring very specific habitats, usually with naturally small distributional ranges of less than 10,000 km2 and the following ecological and life-history traits: • poor powers of dispersal; • confinement to discontinuous habitats; • usually highly seasonal, only active during cooler, wetter periods; and • low levels of fecundity.

Pseudoscorpions are among the most diverse of the smaller arachnid orders, but there is relatively little information about the distribution of these tiny animals, especially in Neotropical caves. Here, we map the distribution of the pseudoscorpions in Brazilian caves and record 12 families and 22 genera based on collections analyzed over several years, totaling 239 caves from 13 states in Brazil. Among them, two families (Atemnidae and Geogarypidae) with three genera (Brazilatemnus Muchmore, 1975, Paratemnoides Harvey, 1991 and Geogarypus Chamberlin, 1930) are recorded for the first time in cave habitats as, well as seven other genera previously unknown for Brazilian caves (Olpiolum Beier, 1931, Pachyolpium Beier 1931, Tyrannochthonius Chamberlin, 1929, Lagynochthonius Beier, 1951, Neocheiridium Beier 1932, Ideoblothrus Balzan, 1892 and Heterolophus To¨mo¨sva´ry, 1884). These genera are from families already recorded in this habitat, which have their distributional ranges expanded for all other previously recorded genera. Additionally, we summarize records of Pseudoscorpiones based on previously published literature and our data for 314 caves.

We studied the natural history and social behavior of Paratemnoides nidi®cator (Balzan 1888) in a tropical savanna system. Females were responsible for all nymphal care. We observed, for the ®rst time in pseudoscorpions, the occurrence of matriphagy behavior by the offspring. During conditions of food deprivation, the mother went out of the nest and passively awaited the protonymphs' attack, not reacting to the capture nor to the nymphs feeding on her body. We suggest that this extreme form of parental care, matriphagy, can reduce cannibalism among protonymphs and facilitate the evolution of social behavior in pseudoscorpions. RESUMO.

  • Pseudoscorpion Wolbachia Symbionts: Diversity and Evidence for a New
    Lefoulon et al. BMC Microbiology (2020) 20:188 https://doi.org/10.1186/s12866-020-01863-y RESEARCH ARTICLE Open Access Pseudoscorpion Wolbachia symbionts: diversity and evidence for a new supergroup S Emilie Lefoulon1,2†, Travis Clark1, Fanni Borveto3, Marco Perriat-Sanguinet3, Catherine Moulia3, Barton E. Slatko1*† and Laurent Gavotte3† Abstract Background: Wolbachia are the most widely spread endosymbiotic bacteria, present in a wide variety of insects and two families of nematodes. As of now, however, relatively little genomic data has been available. The Wolbachia symbiont can be parasitic, as described for many arthropod systems, an obligate mutualist, as in filarial nematodes or a combination of both in some organisms. They are currently classified into 16 monophyletic lineage groups (“supergroups”). Although the nature of these symbioses remains largely unknown, expanded Wolbachia genomic data will contribute to understanding their diverse symbiotic mechanisms and evolution. Results: This report focuses on Wolbachia infections in three pseudoscorpion species infected by two distinct groups of Wolbachia strains, based upon multi-locus phylogenies. Geogarypus minor harbours wGmin and Chthonius ischnocheles harbours wCisc, both closely related to supergroup H, while Atemnus politus harbours wApol, a member of a novel supergroup S along with Wolbachia from the pseudoscorpion Cordylochernes scorpioides (wCsco). Wolbachia supergroup S is most closely related to Wolbachia supergroups C and F. Using target enrichment by hybridization with Wolbachia-specific biotinylated probes to capture large fragments of Wolbachia DNA, we produced two draft genomes of wApol. Annotation of wApol highlights presence of a biotin operon, which is incomplete in many sequenced Wolbachia genomes. Conclusions: The present study highlights at least two symbiont acquisition events among pseudoscorpion species.

Abstract A new pseudoscorpion species, Anatemnus reni sp. nov., belonging to the family Atemnidae Kishida, 1929, is reported from Yunnan Province, Southwest China. The detailed diagnosis, description and illustrations of important morphological characters are presented in this paper. Key words: taxonomy, pseudoscorpion, morphology. Introduction The pseudoscorpion family Atemnidae Kishida, 1929 contains two subfamilies: Atemninae and Miratemninae. The genus Anatemnus Beier, 1932 belongs to the subfamily Atemninae. It was erected by Beier (1932b) for the species Chelifer javanus Thorell, 1883, and currently includes 21 known species which are widespread in Africa, North America, South America, Australia and Asia (Hu and Zhang 2012; Harvey 2013; Alexander et al. 2014). More than half of the species (12) are distributed in Southeast Asia, and only two, A. chaozhouensis Hu and Zhang, 2012 and A. orites (Thorell, 1889), have been recorded in China (Hu and Zhang 2012; Harvey 2013). While examining pseudoscorpion samples collected under bark from Yunnan Province, China, we found one atemnid specimen which conforms to the following generic characters of Anatemnus: distance between trichobothrium it and fingertip equals that between ist and isb; distance between est and esb longer than that between ist and isb; pedipalpal patella not evidently expanded and nearly oval (Beier 1932a; Hu and Zhang 2012).

  • Exploring Species Diversity and Molecular Evolution of Arachnida Through Dna Barcodes
    Exploring Species Diversity and Molecular Evolution of Arachnida through DNA Barcodes by Monica R. Young A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Master of Science in Integrative Biology Guelph, Ontario, Canada ©Monica R. Young, February, 2013 ABSTRACT EXPLORING SPECIES DIVERSITY AND MOLECULAR EVOLUTION OF ARACHNIDA THROUGH DNA BARCODES Monica Rose Young Advisor: University of Guelph, 2012 Professor P.D.N. Hebert This thesis investigates species diversity and patterns of molecular evolution in Arachnida through DNA barcoding. The first chapter assesses mite species richness through comprehensive sampling at a subarctic location in Canada. Barcode analysis of 6279 specimens revealed nearly 900 presumptive species with high rates of turnover between major habitat types, demonstrating the utility of DNA barcoding for biodiversity surveys of understudied taxa. The second chapter explores nucleotide composition, indel occurrence, and rates of amino acid evolution in Arachnida. The results suggest a significant shift in nucleotide composition in the arachnid subclasses of Pulmonata (GC = 37.0%) and Apulmonata (GC = 34.2%). Indels were detected in five apulmonate orders, with deletions being much more common than insertions. Finally, rates of amino acid evolution were detected among the orders, and were negatively correlated with generation length, suggesting that generation time is a significant contributor to variation in molecular rates of evolution in arachnids. ACKNOWLEGEMENTS I would like to thank the members of my advisory committee (Alex Smith, Valerie Behan- Pelletier, and Paul Hebert). In particular, I would like to thank Alex for his insights and assistance with molecular analyses, and Valerie for her enormous effort to identify my oribatids.

  • Redescription of Chelifer Eucarpus DALMAN (Arachnida, Chelonethi, Withiidae) and fi Rst Records of Pseudoscorpions in Copal from Madagascar and Colombia
    Palaeodiversity 3: 33–42; Stuttgart 30 December 2010. 33 Redescription of Chelifer eucarpus DALMAN (Arachnida, Chelonethi, Withiidae) and fi rst records of pseudoscorpions in copal from Madagascar and Colombia MARK L. I. JUDSON Abstract 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 un- known, but it is most likely to be of East African origin (Zanzibar copal). Eucarpus HAGEN, 1870 is a generic nomen nudum, based on a misinterpretation of the binomen Chelifer eucarpus. The fi rst pseudoscorpions from Madagas- can copal are recorded: a male and female of the genus Tyrannochthonius CHAMBERLIN, 1929 (Chthoniidae), and the deutonymphal exuviae of an unidentifi ed genus of Atemninae (Atemnidae). The fi rst pseudoscorpions from Colom- bian copal are recorded: a female of Paratemnoides nidifi cator (BALZAN, 1888) (Atemnidae) and an adult of Pach- ychernes aff. subrobustus (BALZAN, 1892) (Chernetidae) (fi rst record of the genus Pachychernes from Colombia). K e y w o r d s : Pseudoscorpions, copal, East Africa, Madagascar, Colombia, taxonomy. Zusammenfassung Chelifer eucarpus DALMAN, 1826, bisher als ein nomen dubium betrachte, wird anhand des Holotypus, einer Tritonymphe, neu beschrieben und der Gattung Withius KEW, 1911 (Withiidae) zugeordnet. Die Herkunft des Fos- sils ist unbekannt, aber sehr wahrscheinlich stammt es aus Ostafrika (Sansibar-Kopal). Die Gattung Eucarpus HA- GEN, 1870 ist ein nomen nudum, basierend auf einer Fehlinterpretation des Binomens Chelifer eucarpus. Die ersten Pseudoskorpione aus dem Madagaskar-Kopal werden beschrieben: ein Männchen und ein Weibchen der Gattung Tyrannochthonius CHAMBERLIN, 1929 (Chthoniidae) und die Exuvie einer Deuteronymhe einer unbestimmten Gat- tung aus der Unterfamilie Atemninae (Atemnidae).
