Description of the male of Erromyrma Bolton & Fisher, 2016 (Hymenoptera, Aculeata, Formicidae, Myrmicinae)

The male of myrmicine genus Erromyrma is described for the first time on the basis of two male specimens of Erromyrma latinodis collected in northern Madagascar. Moreover, CO1 barcoding confirmed the identification of the male specimens as conspecific with Erromyrma latinodis . We provide a 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.
