“…Immature predators, especially larvae, that attempt to enter nests of a species of Stigmaeopsis ( Schizotetranychus in older literature) on bamboo are attacked and often killed by thrusts of the chelicerae. Male and female spider mites appear to cooperate in defence, with females fi nding and pursuing the predator and males catching and killing them (Saito 1986a(Saito , b , 2010Saito et al 2011 ).…”

“…); however, some predators, such as the phytoseiid mite Typhlodromus bambusae, can intrude into the woven nests. To protect nestmates and their offspring against predatory intruders, adult males and females counterattack the intruders cooperatively and sometimes kill the intruders if they are immature (Saitō, 1986a(Saitō, , 1986bYano et al, 2011;Saito et al, 2011). Males are aggressive not only against predatory intruders but also against conspeci c males.…”

How frequently hybridisation and gene flow occur in the contact zones of diverging taxa is important for understanding the speciation process.Stigmaeopsis sabelisi and Stigmaeopsis miscanthi HG form are haplodiploid, social spider mites that infest the Chinese silver grass, Miscanthus sinensis. These two species are closely related and parapatrically distributed in Japan. In mountainous areas, S. sabelisi and S. miscanthi HG form are often found in the highlands and lowlands, respectively, suggesting that they are in contact at intermediate altitudes. It is estimated that they diverged from their common ancestors distributed in subtropical regions (south of Japan) during the last glacial period, expanded their distribution into the Japanese Archipelago, and came to have such a parapatric distribution (secondary contact). As their reproductive isolation is strong but incomplete, hybridisation and genetic introgression are expected at their distributional boundaries. In this study, we investigated their spatial distribution patterns along the elevation on Mt. Amagi using male morphological differences and investigated their hybridisation status using single-nucleotide polymorphisms by MIG-seq. We found their contact zone at altitudes of 150–430 m, suggesting that their contact zone is prevalent in the parapatric area, which is in line with a previous study. Interspecific mating was predicted based on the sex ratio in the contact zone. However, no obvious hybrids were found, and genetic introgression was estimated to be extremely low. Here, we discuss why gene flow is extremely restricted to the contact zone.

“…However, information about the counterattack efficiency of S. nanjingensis is still incomplete, although its behaviour has been tentatively described (Zhang, 2002;Saito et al, 2016). (Saito, 1986a(Saito, ,1986bMori & Saito, 2005;Saito et al, 2011;Yano et al, 2011). (Saito, 1986a(Saito, ,1986bMori & Saito, 2005;Saito et al, 2011;Yano et al, 2011).…”

“…Thus we observed the effects of S. nanjingensis counterattack behaviour against T. bambusae, a common predator of Stigmaeopsis species in Japan and China, using the same method adopted for similar studies on other Stigmaeopsis spp. (Saito, 1986a(Saito, ,1986bMori & Saito, 2005;Saito et al, 2011;Yano et al, 2011).…”

1. A type of arms race that includes predation, counterattacks and cross-counterattacks occurs between the phytophagous mite Stigmaeopsis nanjingensis (Ma et Yuan), which lives in self-woven nests and exhibits cooperative sociality, and its specialised phytoseiid mite predator, Typhlodromus bambusae Ehara.2. First, the efficiency of the S. nanjingensis (prey) counterattacking T. bambusae (predator) was observed. The prey females frequently locked the immature predators out of their nests using silk web, and the predators subsequently died of starvation. Furthermore, the prey males often killed immature T. bambusae mites after they invaded the nests.3. This reversal of roles in the predator-prey system was then re-reversed (returned to a normal state) by the behaviour of T. bambusae females. Immature predators could maintain their predacious natures due to the presence of attending adult females, which are able to cope with the prey counterattack behaviours.
