This diversity, together with absence of a common coevolving symbiont (such as &lt;jats italic=&quot;&quot;&gt;Buchnera&lt;/jats&gt;, in aphids), indicates that sucking lice underwent a series of symbiont acquisitions, losses, and replacements. To better understand evolution and significance of louse symbionts, genomic and phylogenetic data are needed from a broader taxonomic diversity of lice and their symbiotic bacteria. In this study, we extend the known spectrum of the louse symbionts with a new lineage associated with &lt;jats italic=&quot;&quot;&gt;Neohaematopinus pacificus&lt;/jats&gt;, a louse species that commonly parasitizes North American chipmunks. The recent coevolutionary analysis showed that rather than a single species, these lice form a cluster of unique phylogenetic lineages specific to separate chipmunk species (or group of closely related species). Using metagenomic assemblies, we show that the lice harbor a bacterium which mirrors their phylogeny and displays traits typical for obligate mutualists. Phylogenetic analyses place this bacterium within Enterobacteriaceae on a long branch related to another louse symbiont, &amp;ldquo;&lt;jats italic=&quot;&quot;&gt;Candidatus&lt;/jats&gt; Puchtella pedicinophila.&amp;rdquo; We propose for this symbiotic lineage the name &amp;ldquo;&lt;jats italic=&quot;&quot;&gt;Candidatus&lt;/jats&gt; Lightella neohaematopini.&amp;rdquo; Based on the reconstruction of metabolic pathways, we suggest that like other louse symbionts, &lt;jats italic=&quot;&quot;&gt;L. neohaematopini&lt;/jats&gt; provides its host with at least some B vitamins. In addition, several samples harbored another symbiotic bacterium phylogenetically affiliated with the Neisseriales-related symbionts described previously from the lice &lt;jats italic=&quot;&quot;&gt;Polyplax serrata&lt;/jats&gt; and &lt;jats italic=&quot;&quot;&gt;Hoplopleura acanthopus&lt;/jats&gt;. Characterizing these bacteria further extend the known diversity of the symbiotic associations in lice and show unique complexity and dynamics of the system.&lt;/jats&gt;&lt;/p&gt;
