The latin species name polyctena is from Greek and literally means 'many cattle', referring to the species' habit of farming aphids for honeydew food. [2]
Beginning in the 1990s, molecular (DNA sequence) data have come to play a central role in attempts to reconstruct the ant "tree of life".Molecular phylogenetic analyses based on multiple nuclear genes have yielded robust results that reinforce some preexisting views but overturn others – and suggest that there has been considerable morphological convergence among some ant lineages.
The family Formicidae belongs to the order Hymenoptera, which also includes sawflies, bees, and wasps. Ants evolved from a lineage within the stinging wasps, and a 2013 study suggests that they are a sister group of the Apoidea. [9] However, since Apoidea is a superfamily, ants must be upgraded to the same rank. [10]

Head of a blind worker. Adetomyrma venatrix was described on the basis of specimens belonging to the worker caste collected from Zombitse Forest, in western Madagascar. The key characteristics of the species was the absence of a clear petiole when viewed from above due to the third abdominal tergite (the sclerite on the dorsal side) lacking a differentiated pretergite.
