Remarks on taxonomic status:

The mono-typic genus Aulonocranus with the type-species A. dewindti stands out from all other species in the tribe Ectodini, by the presence of sensory pores in the head region. The molecular analyses of Koblmüller et al. (2004) showed that Aulonocranus form a subclade within the Ophthalmotilapia-clade, together with the genera Cunningtonia, Ectodus and Lestradea, and that Aulonocranus dewindti may form a species-pair together with Cunningtonia longiventralis.
