Stigmatomma emeryi

Stigmatomma emeryi is found near Algeciras and in Ceuta (Tinaut, Ruano, and Martinez, 2011c). This species ecology and natural history is regarded to be very similar to A. ghilianii’s (Tinaut et al., 2011b; Tinaut et al., 2011c, Jowers 2015). S emeryi has a similar distribution pattern as Technomyrmex vexatus and Anochetus ghilianii, occurring on both sides of the Strait of Gibraltar and having a very restricted range on at least one side of the Strait. A genetic study (Jowers et al. 2015) suggested the distribution of A. ghilianii is not explained by this species having been present prior to the closing of a land connection between these two areas, i.e., > 5 MYA. It was more likely moved across the strait by humans. They speculated the distribution of Stigmatomma emeryi has a similar explanation.
