“…Sakagami et al (2009) Two behavioral phenotypes of S. miscanthi, the low-aggression (LW) and high-aggression (HG) phenotypes based on male aggressiveness, were previously reported (Saito & Sahara 1999;Sato et al 2008Sato et al , 2013. The two phenotypes were basically shown to be two separate clades based on their nuclear 28S gene (Sakagami et al 2009) and COI gene of mtDNA (Ito & Fukuda 2009). In our study, these two phenotypes also formed different clades and the Sm_(Cn) strain of S. miscanthi formed a third clade (Figs.…”

“…Hypotheses about the evolutional relationship of Stigmaeopsis species have been based on molecular analysis, morphology and host plants (Sakagami et al 2009;Ito & Fukuda 2009;Ito et al 2011). In this study, we were unable to determine a comprehensive phylogeny of Stigmaeopsis.…”

“…These five Japanese species were reported to belong to five distinct groups based on the COI gene of mtDNA (Ito & Fukuda 2009;Ito et al 2011). Based on the 28S rRNA gene, these five species were clearly divided into two groups, which well corresponded to the host plants (bamboo species and Miscanthus grass species, respectively) (Sakagami et al 2009).…”

Some intraspecific groups were reported from two species, S. miscanthi and S. longus, based on phylogenetic analyses (Sakagami et al 2009;Ito & Fukuda 2009;Ito et al 2011).

“…S. miscanthi has two behavioral phenotypes based on differences in male pugnacity against conspecific males. The two phenotypes have been called the low-aggression (LW) phenotype and the high-aggression (HG) phenotype (Saito & Sahara 1999;Sato et al 2008Sato et al , 2013, and these phenotypes formed distinct groups in phylogenetic trees of the 28S rRNA gene (Sakagami et al 2009) and COI gene (Ito & Fukuda 2009;Ito et al 2011). S. longus also forms two distinct groups in a phylogenetic tree based on the COI gene; one is distributed in the northern part of Japan (from Hokkaido Prefecture to Yamagata Prefecture) and the other is distributed in the southern part of Japan (from Yamagata Prefecture to the Kyushu district), suggesting that there were two routes of expansion of this species (Ito et al 2011).…”

Similar nest-weaving habits and sociality characterize all the species belonging to the recently reinstated spider mite genus Stigmaeopsis. Molecular phylogenetic analysis using 28S rDNA shows that Stigmaeopsis forms a distinct clade and that there is another unrecognized clade involving Schizotetranychus species with comparable nest-weaving habits distributing in tropical regions. Furthermore, the phylogenic hypothesis suggests that Stigmaeopsis miscanthi (Saito) inhabiting Miscanthus sinensis Anderss. shared a common ancestor with Stigmaeopsis longus (Saito) inhabiting Sasa senanensis (Franch. et Sav.), both mite species having very similar social systems. We confirmed reproductive isolation between them and tested the suitability of the two plant species as hosts for these two mite species. The result that S. miscanthi immatures could survive on Sasa bamboo for a long period, but S. longus immatures could not survive on Miscanthus grass suggested that the former has evolved from a common ancestor living on Sasa bamboo. This is also supported by a third piece of indirect evidence obtained from observing mite responses to the plant-originated chemical cues involving feces used for waste management in these species. Therefore, we conclude that the host plant shift of S. miscanthi from Sasa bamboo to M. sinensis played a key role in speciation.

When males fight for access to females, such conflict rarely escalates into lethal fight because the risks and costs involved, that is, severe injury or death, are too high. The social spider mite, Stigmaeopsis miscanthi, does exhibit lethal male fights, and this male–male aggressiveness varies among populations. To understand the evolution of lethal fighting, we investigated aggressiveness in 42 populations and phylogenetic relationships in 47 populations along the Japanese archipelago. By analysis of the male weapon morph, a proxy for aggressiveness, we confirmed the existence of a mildly aggressive (ML) form, besides the low aggression (LW) and high aggression (HG) forms reported earlier. To evaluate demographic history of these three forms, we employed the approximate Bayesian computation approach using mtCOI sequences and taking into consideration the postlast glacial expansion history of the host plant, Miscanthus sinensis . As results, hierarchical split models are more likely to explain the observed genetic pattern than admixture models, and the ML form in the subtropical region was considered the ancestral group. The inferred demographic history was consistent with the one reconstructed for the host plant in a previous study. The LW form was split from the ML form during the last glacial period (20,000–40,000 years BP), and subsequently, the HG form was split from the ML form at the end of or after the last glacial period (5,494–10,988 years BP). The results also suggest that the mite invaded Japan more than once, resulting in the present parapatric distribution of LW and HG forms in eastern Japan.

Male–male aggression peaks at intermediate relatedness in a social spider mite

Theory predicts that when individuals live in groups or colonies, male-male aggression peaks at intermediate levels of local average relatedness. Assuming that aggression is costly and directed toward nonrelatives and that competition for reproduction acts within the colony, benefits of aggressive behavior are maximized in colonies with a mix of related and unrelated competitors because aggression hurts nonkin often, thereby favoring reproduction of kin. This leads to a dome-shaped relation between male-male aggression and average relatedness. This prediction has been tested with bacteria in the laboratory, but not with organisms in the field. We study how male-male aggression varies with relatedness in the social spider mite Stigmaeopsis miscanthi. We sampled 25 populations across a wide geographic range between Taiwan and Japan, representing a gradient of high to low within-population relatedness. For each population the weaponry of males was measured as the length of the first pair of legs, and male-male aggression was tested by placing pairs of nonsibling males together and scoring the frequency of male death over a given period. As these two morphological and behavioral variables correlate strongly, they both reflect the intensity of male-male conflict. Our data on the social spider mite show that male-male aggression as well as weapon size strongly peak at intermediate, average relatedness, thereby confirming theoretical predictions.
