What is "apomyrma"

Apomyrma stygia is a species of ant found in West Africa, first described in 1970 (1970). It is the only species in the genus Apomyrma. A newly described species, Opamyrma hungvuong, is apparently related to Apomyrma. It has been suggested the ant primarily lives in tropical forests, and apparently belongs to a guild of centipede feeding ants.
