Abstract Background Wolbachia are the most widely spread endosymbiotic bacteria, present in a wide variety of insects and two families of nematodes, but as of now, 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 w Gmin and Chthonius ischnocheles harbours w Cisc, both closely related to supergroup H, while Atemnus politus harbours w Apol, a member of a novel supergroup S along with Wolbachia from the pseudoscorpion Cordylochernes scorpioides ( w Csco), 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 w Apol. Annotation of w Apol 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. Phylogenomic analysis indicates that the Wolbachia from Atemnus politus ( w Apol), forms a separate supergroup ("S") with the Wolbachia from Cordylochernes scorpioides (w Csco). Interestingly, the biotin operon, present in w Apol, appears to have been horizontally transferred multiple times along Wolbachia evolutionary history.

Cordylochernes Scorpioides

Em sete municípios do Amazonas, um de Rondônia e um de Roraima, foram examinadas 71 colônias de 24 espécies de Passalidae (Coleoptera), pertencentes aos gêneros: Passalus Fabricius, 1792 (14 espécies); Paxillus Mac Leay, 1819 (três); Popilius Kaup, 1871 (três); Spasalus Kaup, 1869 (uma); Verres Kaup, 1871 (uma); Veturius Kaup, 1871 (duas). Foram registradas doze espécies de pseudoscorpiões, incluindo nove gêneros e cinco famílias, listadas a seguir: Chernetidae - Americhernes aff. incertus Mahnert, 1979, Cordylochernes scorpioides (Linnaeus 1758), Lustrochenes similis (Balzan 1892), L. aff. reimoseri Beier, 1932, L. intermedius (Balzan 1892), Phymatochernes crassimanus Mahnert 1979; Chthoniidae - Pseudochthonius homodentatus Chamberlin, 1929; Lechytiidae - Lechytia chthoniiformis (Balzan 1887); Tridenchthoniidae - Tridenchthonius mexicanus Chamberlin & Chamberlin 1945; Withiidae - Cacodemonius sp., Dolichowithius (D.) emigrans (Tullgren 1907), D. (D.) mediofasciatus Mahnert, 1979. Dentre as espécies mais freqüentes (T. mexicanus, L. intermedius e L. aff. reimoseri), ocorreram todos os estágios de desenvolvimento. Foram coletadas de uma a três espécies de pseudoscorpiões em cada colônia individual de besouros passalídeos. T. mexicanus foi a única espécie encontrada em todos os municípios, ocorrendo em 45 colônias de dezenove espécies de passalídeos, sendo a maioria dos exemplares encontrado no subcórtex. L. intermedius foi a segunda espécie mais abundante, ocorrendo em colônias de 11 espécies de Passalidae, a maioria também no subcórtex. L. aff reimoseri ocorreu em 13 colônias de Passalidae, sob a casca, alburno e cerne. L. aff. reimoseri foi a única espécie coletada somente no cerne.

Atta Colombica

Waste heaps of Atta are host to an extraordinary diversity of myrmecophiles insects and other arthropods. In this study, the presence of four species of pseudoscorpions is recorded in two Atta colombica waste heaps in the years 2016 and 2017. Two of these species, Cordylochernes scorpioides and Lustrochernes carolinensis are new records in waste heaps and except for the deutonymphs of L.carolinensis, the others all stages of post-embryonic development were present in the studied heaps, which could indicate that these two species carry out their entire life cycle in these waste mounds and live there permanently.
