“…They found that the endosymbiont of Pedicinus obtusus represented a primary endosymbiont independent of C. Riesia , and proposed the name Candidatus Puchtella . Interestingly, phylogenetic reconstruction placed C. Puchtella close to Wigglesworthia , the primary endosymbiont of tsetse flies [35]. Like C. Riesia , C. Puchtella is another louse primary endosymbiont that is closely related to an endosymbiont of a non‐louse blood‐feeding insect.…”

“…A sister clade to the hominid lice is the Pedicinidae, comprising the lice of cercopithecid primates [6]. Fukatsu et al [35] were the first to investigate the phylogenetic placement of primary endosymbionts in the Pedicinidae. They found that the endosymbiont of Pedicinus obtusus represented a primary endosymbiont independent of C. Riesia, and proposed the name Candidatus Puchtella.…”

Recent studies of molecular and genomic data from the parasitic lice of birds and mammals, as well as their mutualistic endosymbiotic bacteria, are changing the phylogenetic relationships and taxonomy of these organisms. Phylogenetic studies of lice suggest that vertebrate parasitism arose multiple times from free-living book and bark lice. Molecular clocks show that the major families of lice arose in the late Mesozoic and radiated in the early Cenozoic, following the radiation of mammals and birds. The recent release of the human louse genome has provided new opportunities for research. The genome is being used to find new genetic markers for phylogenetics and population genetics, to understand the complex evolutionary relationships of mitochondrial genes, and to study genome evolution. Genomes are informing us not only about lice, but also about their obligate endosymbiotic bacteria. In contrast to lice and their hosts, lice and their endosymbionts do not share common evolutionary histories, suggesting that endosymbionts are either replaced over time or that there are multiple independent origins of symbiosis in lice. Molecular phylogenetics and whole genome sequencing have recently provided the first insights into the phylogenetic placement and metabolic characteristics of these distantly related bacteria. Comparative genomics between distantly related louse symbionts can provide insights into conserved metabolic functions and can help to explain how distantly related species are fulfilling their role as mutualistic symbionts. In lice and their endosymbionts, molecular data and genome sequencing are driving our understanding of evolutionary relationships and classification, and will for the foreseeable future.

“…However, the proposed alternatives are long and somewhat awkward Procabacter [83] Procaibacter Based on Appendix 9, the connecting vowel -i-is needed Procabacter acanthamoebae [83] Procaibacter acanthamoebae Based on Appendix 9, the connecting vowel -i-is needed Profftia virida [45] Profftia adelgidis According to Appendix 9, the genitive case of the generic name of the associated organism (Adelges) must be used. Moreover, the epithet virida is malformed Protistobacter heckmanni [84] Protistobacter heckmannii According to Appendix 9, the correct way to form a specific epithet as a genitive noun for a male person whose name ends on -n is to add -ii Puchtella pedicinophila [85] Puchtella pediciniphila Based on Appendix 9, the connecting vowel -i-is needed Rhizobium massiliae [14] Rhizobium massiliense The Latin Massilia with the neuter ending for 'geographical' adjectives -ense gives massiliense Rickettsia amblyommii [86] Rickettsia amblyommatis The genitive of Amblyomma is not amblyommii but (as based on Greek o ' a, genitive o ' ato&) amblyommatis Rickettsia andeanae [87] Rickettsia andeana The authors made an adjective in the genitive case, for which there is no precedent Candidatus name Reference Suggested corrected name Comments in the nomenclature. Possible is andesensis, but the adjective andeanus, -a, -um is widely used Rickettsia asemboensis [88] Rickettsia asembonensis According to Appendix 9, asemboensis must be corrected to asembonensis Rickettsia barbariae [89] Rickettsia barbarica I found no confirmation for the statement by the authors that the name Barbaria was given by the Romans to the mountains of Sardina; it was a general term for the foreign, the uncultivated world.…”

A plea for linguistic accuracy – also for Candidatus taxa

While all names of new taxa submitted to the International Journal of Systematic and Evolutionary Microbiology, either in direct submissions or in validation requests for names effectively published elsewhere, are subject to nomenclatural review to ensure that they are acceptable based on the rules of the International Code of Nomenclature of Prokaryotes, the names of Candidatus taxa have not been subjected to such a review. Formally, this was not necessary because the rank of Candidatus is not covered by the Code, and the names lack the priority afforded validly published names. However, many Candidatus taxa of different ranks are widely discussed in the scientific literature, and a proposal to incorporate the nomenclature of uncultured prokaryotes under the provisions of the Code is currently pending. Therefore, an evaluation of the names of Candidatus taxa published thus far is very timely. Out of the~400 Candidatus names found in the literature, 120 contradict the current rules of the Code or are otherwise problematic. A list of those names of Candidatus taxa that need correction is presented here and alternative names that agree with the provisions of the Code are proposed.

“…If the most similar sequence from a BLAST search (Altschul et al, 1990) of the non-redundant nucleotide database in GenBank was from an endosymbiont, we identified the sequences as endosymbionts We also downloaded from GenBank 12 endosymbiont sequences from sucking lice and Rhynchophthirina chewing lice (Accessions: DQ076661, DQ076662, DQ076665, DQ076664, EU827263, AB478979, EF110571, EF110573, DQ076667, DQ076666, EF110571, DQ076663; Hypsa & Kirizek 2007;Allen et al, 2009;Fukatsu et al, 2009). Rhynchophthirina is a suborder of blood-feeding chewing lice that is the sister group to Anoplura (Cruickshank et al, 2001;Barker et al, 2003;Johnson, Yoshizawa, & Smith, 2004;Yoshizawa & Johnson, 2010).…”

We estimated the number of louse endosymbiont lineages using both newly obtained and previously sequenced 16S rDNA bacterial sequences and more than 42,000 16S rDNA sequences from other Gammaproteobacteria. We also performed parametric and nonparametric bootstrapping experiments to examine the effects of phylogenetic error and uncertainty on these estimates. We found that sampling of 16S rDNA sequences affected the estimates of endosymbiont diversity in sucking lice until we reached a threshold of genetic diversity. Sampling by maximizing the diversity of 16S rDNA sequences was more efficient than simply randomly sampling available 16S rDNA Phthirapatera: Anoplura).

Sampling by maximizing the diversity of 16S rDNA sequences was more efficient than simply randomly sampling available 16S rDNA sequences. Although simulation results support the finding of multiple endosymbiont lineages in sucking lice, the bootstrap results suggest that there is still uncertainty in estimates of the number of endosymbiont origins inferred from 16S rDNA alone.
