The male of the myrmicine genus Erromyrma is described for the first time on the basis of two specimens of Erromyrmalatinodis (Mayr, 1872) collected in northern Madagascar. We used COI barcoding to confirm the identification of the male specimens as conspecific with Erromyrmalatinodis. We provide an illustrated male-based key to the four Myrmicinae tribes (Attini, Crematogastrini, Solenopsidini, Stenammini) and to the Solenopsidini genera (Adelomyrmex, Erromyrma, Solenopsis, Syllophopsis and Monomorium) for the Malagasy region.
Keywords: Erromyrma; Madagascar; Myrmicinae; Solenopsidini; male ants; morphology.
