Figure 6 in Phylogeny and coevolutionary associations of makialgine mites (Acari, Psoroptidae, Makialginae) provide insight into evolutionary history of their hosts, strepsirrhine primates
Figure 6. Preferred TreeMap reconstruction of coevolutionary associations between strepsirrhine primates (bold) and makialgine mites using morphological data (see Table 4, no. 3). Filled circles indicate cospeciation, empty circles with crosses indicate extinctions, arrows indicate host switches, empty squares indicate speciation within a host lineage (duplication). As the multihost Lemuralges intermedius was arbitrarily restricted to Lemuridae only (see Material and methods), reconstructions involving Lemuralges (shown in grey) are incomplete and those involving Gaudalges may be biased because of this.
Figure 5 in Phylogeny and coevolutionary associations of makialgine mites (Acari, Psoroptidae, Makialginae) provide insight into evolutionary history of their hosts, strepsirrhine primates
Figure 5. Exploration of cost space to evaluate different coevolutionary scenarios in the observed association between strepsirrhine primates and makiagine mites using morphological data (codivergence cost is set to 0, extinction cost is set to 1). A, probability (P-values) was estimated using 100 000 permutations of both host and parasite terminals with a cospeciation cost and extinction cost of 0 and 1, respectively; B, significant values (P <0.05) are shaded and shown in detail. Dashed lines demark the cost space that corresponds to six significant coevolutionary models (as given in Table 3).

Testing the potential contribution of Wolbachia to speciation when cytoplasmic incompatibility becomes associated with host‐related reproductive isolation
<p>Endosymbiont induced cytoplasmic incompatibility (CI) may play an important role in arthropod speciation. However, whether CI consistently becomes associated or coupled with other host-related forms of reproductive isolation (RI) to impede the transfer of endosymbionts between hybridizing populations and further the divergence process remains an open question. Here, we show varying degrees of pre- and post-mating RI exist among allopatric populations of two interbreeding cherry-infesting tephritid fruit flies (<i>Rhagoletis cingulata</i> and <i>R. indifferens</i>) across North America. These flies display allochronic and sexual isolation among populations, as well as unidirectional reductions in egg hatch in hybrid crosses involving southwestern USA males. All populations are infected by a <i>Wolbachia </i>strain, <i>w</i>Cin2, whereas a second strain, <i>w</i>Cin3, only coinfects flies from the Southwest USA and Mexico. Strain <i>w</i>Cin3 is associated with a unique mtDNA haplotype and unidirectional postmating RI, implicating the strain as the cause of CI. When coupled with non-endosymbiont RI barriers, we estimate the strength of CI associated with <i>w</i>Cin3 would not prevent the strain from introgressing from infected Southwestern to uninfected populations elsewhere in the USA if populations were to come into secondary contact and hybridize. In contrast, cytoplasmic-nuclear coupling may be sufficient to impede the transfer of <i>w</i>Cin3 if Mexican and USA populations were to come into contact. We discuss our results in the context of the general paucity of examples demonstrating stable <i>Wolbachia</i> hybrid zones and whether the spread of <i>Wolbachia</i> among taxa can be constrained in natural hybrid zones long enough for the endosymbiont to participate in speciation.</p>
