Eusocial Species

Eusocial insects can express surprisingly complex cooperative defence of the colony. Brood and reproductive castes typically remain in the nest and are protected by workers' various antipredator tactics against intruders. In Madagascar, a myrmicine ant, Aphaenogaster swammerdami , occurs sympatrically with a large blindsnake, Madatyphlops decorsei . As blindsnakes generally specialize on feeding on termites and ants brood by intruding into the nest, these snakes are presumably a serious predator on the ant. Conversely, a lamprophiid snake, Madagascarophis colubrinus , is considered to occur often in active A . swammerdami nests without being attacked. By presenting M . colubrinus , M . decorsei and a control snake, Thamnosophis lateralis , at the entrance of the nest, we observed two highly specialized interactions between ants and snakes: the acceptance of M . colubrinus into the nest and the cooperative evacuation of the brood from the nest for protection against the ant-eating M . decorsei . Given that M . colubrinus is one of the few known predators of blindsnakes in this area, A . swammerdami may protect their colonies against this blindsnake by two antipredator tactics, symbiosis with M . colubrinus and evacuation in response to intrusion by blindsnakes. These findings demonstrate that specialized predators can drive evolution of complex cooperative defence in eusocial species.

The new zodariid genus Suffascar, gen. nov. is described from Madagascar. It is apparently endemic to the island, common and speciose. Twelve new species were discovered and are here described: Suffascar albolineatus, sp. nov., S. fianara, sp. nov., S. fisheri, sp. nov., S. fitzpatrickae, sp. nov., S. gigas, sp. nov., S. griswoldi, sp. nov., S. macromma, sp. nov., S. micromma, sp. nov., S. nonus, sp. nov., S. scutatus, sp. nov., S. sufficiens, sp. nov. and S. tofti, sp. nov. It is well known that Zodariidae with femoral organs are specialised consumers of ants or termites, although the exact role of these glands still remains obscure. Suffascar is part of the ‘dual femoral organ clade’ (DF), which also includes Asceua Thorell, 1887, Suffasia Jocqué, 1991, and Suffrica Henrard & Jocqué, 2015. Using a morphology-based phylogenetic analysis, we test whether zodariids sharing the dual femoral organ are part of the same group as the ‘single femoral organ clade’ (SF) or form a separate monophyletic group. It appears that SF and DF constitute clearly monophyletic entities with a sister-group relation. These groups may be considered as distinct subfamilies and, together, they may turn out to be sister to the Storeninae (which then could be re-established). An analysis that focuses on these questions is underway. http://zoobank.org/urn:lsid:zoobank.org:pub:281E1357-FAEE-4300-B1BB-F0D43E724E91
