“…This tree was highly congruent with the other 21 maximum likelihood trees we inferred, as 56 of 67 internal branches were identical among the 22 trees, with ultrafast bootstrap support >95% (Figure 1). Our trees were also largely congruent with previously published phylogenies based on mitogenomes [6,26,27,30,31]. Congruent placement of lineages among all our trees and previously obtained mitogenome trees include Mastotermitidae as the earliest branching termite lineage; the sister group relationship between Kalotermitidae and Neoisoptera; the sister-group relationship between Stylotermitidae and other Neoisoptera; and the polyphyletic nature of Rhinotermitidae, within which the monophyletic Serritermitidae and Termitidae are nested (Figure 1).…”

Termites play a major role in a variety of ecological processes in tropical and subtropical biomes worldwide, such as decomposition, soil formation and aeration, and nutrient cycling. These important ecosystem services were achieved through their highly complex societies and remarkable adaptations, including the evolution of sterile worker castes, the acquisition of endosymbionts, and the capacity for extensive environmental engineering, yet the causes and consequences of their ecological success are still poorly understood. The goals of our study were (1) to provide the first complete, species-level phylogeny of all currently recognized termite species by integrating the available genetic and taxonomic data, as well as methods of phylogenetic imputation and divergence time estimation; and (2) to explore variation in speciation rates among termite lineages. We provide the inferred relationships as a set of 1,000 pseudo-posterior trees, which can be used in future comparative analyses. We demonstrate that speciation rates have been relatively constant throughout the history of termites, with two positive shifts in speciation rates: one at their origin of Euisoptera and the other concordant with evolution of Termitidae. On the other hand, there was no obvious trend towards deceleration in speciation rates for termites as a whole, nor within the most species-rich families. The provided trees might represent a valuable resource for termite comparative studies by summarizing the available phylogenetic information, while accounting for uncertainty in the inferred topologies.

“…3Records of frequent occurrences of thelytokous parthenogenesis in natural populations of termites, mapped on a schematic and simplified phylogenetic tree ( a ), including a detailed view on phylogenetic relationships within the Termes group, studied here ( b ). These trees are compiled from phylogenetic reconstructions using full mitochondrial genomes [21, 41–43]. Current knowledge suggests that AQS evolved at least six times independently —three times in the genus Reticulitermes , twice in the Syntermitinae and at least once in the Termes group.…”

Widespread occurrence of asexual reproduction in higher termites of the Termes group (Termitidae: Termitinae)

Background A decade ago, the mixed reproductive strategy Asexual Queen Succession (AQS) was first described in termites. In AQS species, the workers, soldiers and dispersing reproductives are produced through sexual reproduction, while non-dispersing (neotenic) queens arise through automictic thelytokous parthenogenesis, replace the founding queen and mate with the founding king. As yet, AQS has been documented in six species from three lineages of lower (Rhinotermitidae) and higher (Termitinae: Termes group and Syntermitinae) termites. Independent evolution of the capacity of thelytoky as a preadaptation to AQS is supported by different mechanisms of automixis in each of the three clades. These pioneering discoveries prompt the question on the extent of thelytoky and AQS in the diversified family of higher termites. Results Here, we investigated the capacity of thelytoky and occurrence of AQS in three species from the phylogenetic proximity of the neotropical AQS species Cavitermes tuberosus (Termitinae: Termes group): Palmitermes impostor , Spinitermes trispinosus , and Inquilinitermes inquilinus . We show that queens of all three species are able to lay unfertilized eggs, which undergo thelytokous parthenogenesis (via gamete duplication as in C. tuberosus ) and develop through the transitional stage of aspirants into replacement neotenic queens. Conclusions The breeding system in P. impostor is very reminiscent of that described in C. tuberosus and can be characterized as AQS. In the remaining two species, our limited data do not allow classifying the breeding system as AQS; yet, also in these species the thelytokous production of neotenic females appears to be a systematic element of reproductive strategies. It appears likely that the capacity of thelytokous parthenogenesis evolved once in the Termes group, and may ultimately be found more widely, well beyond these Neotropical species.
